Buttery Apple Streusel Oat Squares

by Angela (Oh She Glows) on October 26, 2010


Luckily my mother-in-law warned me of an impending storm today (we might get a tornado tonight!), so that was inspiration to get in the run I was procrastinating all morning. I had a great 4.5 mile run in about 38 mins and a balmy 18C temperature. We are having a heat wave this week and it was so nice to run in the warm weather, even if it was raining.

As for the tornado warning, I’m hoping it doesn’t get that ugly! Right now, it is quite windy and rainy and seems to be picking up…

In other news, I’m madly in love with these Healthy Strawberry Oat Squares.


Crazy, in that I had to put them in the freezer immediately so I didn’t eat them all and I should probably be committed or better yet, in a straitjacket.

Eric and I have been enjoying a square after dinner each night and we arm wrestled over the last square.


It wasn’t pretty, but in the end he split it with me. ;)

As soon as I made the strawberry jam squares, my mind was flooded with ways that I could adapt them…

  • Apple
  • Pear
  • Pumpkin butter
  • Figs
  • Sweet Potato or butternut squash
  • Chocolate banana
  • Blueberry jam


Up second: Apple Streusel.



Ashley made the oat squares into a lovely apple variety, so I decided to follow suit and used her topping as a guide. I decided to make an apple streusel topping as well, adapting the topping from one of my favourite muffin recipes of all time.


Buttery Apple Streusel Oat Squares

Adapted from Strawberry Oat Squares and pumpkin apple streusel muffins.


For Oat Base:

  • 1.5 cups regular oats
  • 1 cup whole-grain Kamut flour (or whole wheat pastry flour or white/whole wheat)
  • 1/2 tsp baking soda
  • 1/2 tsp sea salt
  • 1/2 cup Sucanat sugar (or brown sugar)
  • 1 chia egg (1 tbsp chia seeds+ 4 tbsp warm water, mixed well and set aside for 5 mins)
  • 1/2 cup + 2 tbsp Earth Balance, melted
  • 1/4 cup pure maple syrup
  • 1 tsp pure vanilla extract
  • 2 tbsp almond milk


For Buttery Apple Mixture:


  • 3 granny Smith Apples, peeled, thinly sliced, chopped (makes approx 3 cups, chopped)
  • 2 tbsp Earth balance or butter
  • 1 tbsp maple syrup or brown rice syrup
  • 1 tbsp Sucanat (or brown sugar)
  • 3/4 tsp cinnamon
  • 1/2 tsp ginger
  • 1/4 tsp nutmeg
  • Pinch sea salt


Apple Streusel Topping:


  • 2 tbsp Sucanat (or brown sugar)
  • 1 tbsp Earth Balance or butter
  • 2 tbsp flour
  • 1/2 tsp ground cinnamon


Directions: Preheat oven to 350F. Line a square pan (I used a 9×9) with parchment paper and oil the sides of the pan and base. In a medium sized pot, add the apple mixture ingredients (chopped apples, Earth Balance, brown rice or maple syrup, spices). Heat over low, stirring frequently for about 10 minutes, until the apples soften and mixture thickens up.

In a small bowl, mix the chia or flax egg and set aside. In a large bowl, mix the oat base dry ingredients: oats, flour, Sucanat/brown sugar, baking soda, salt. In a small bowl, mix the melted earth balance, maple syrup, almond milk, vanilla, and chia egg. Stir well.

Add the wet mixture to the dry and mix well, using hands if necessary. Set aside 1/2 cup of the oat base mixture if desired. Pour the oat mixture onto the square pan and press down with fingers. Use a pastry roller to smooth out if desired. Pour on cooked apple mixture and smooth out. Make the apple streusel topping by mixing all ingredients together with a fork or fingers. Now sprinkle on the reserved 1/2 cup oat mixture and apple streusel topping and sprinkle over top.

Bake at 350F for approximately 30 minutes. Allow to fully cool for at least 30-40 minutes before gently removing from pan. You can firm them up in the fridge before slicing into squares or bars. The bars also freeze very well (I place them into a container in the freezer).


I ended up using three large Grannies when I decided that two wasn’t enough for the topping!


Peel the apples and slice, slice, slice and chop, chop, chop.


and eat the peel with some cinnamon sprinkled on with a bit of maple syrup. Keep that doc away! ;)


Make the apple mixture on the stove top.


Mix dry ingredients.


By mistake, I added the chia egg to the dry ingredients without thinking, but it technically should have been in the wet ingredients below. Rest assured if you do this too, it will still turn out! :)

Add wet to dry.


Mix it up!

20101026-IMG_8832 20101026-IMG_8838

Spread and roll.


Add on Apple Mixture.


Admire the beauty before you.


Make the cinnamon streusel topping.

20101026-IMG_8857 20101026-IMG_8860

And cover the top.

20101026-IMG_8866 20101026-IMG_8872

Freshly grated cinnamon on top, if desired.


Bake for 30 minutes at 350F and then allow to cool for at least 30 minutes. You can also firm them up in the fridge before slicing as they will be crumbly.

You can make them into squares….triangles…

20101026-IMG_8897 20101026-IMG_8901

and even bars!


The verdict?

Delicious. Seasonal. Rustic. Not too sweet.

I forgot to reserve 1/2 cup of the oat mixture to sprinkle on top and I missed it. Next time, I would definitely do that again as it added a fun texture on top. They would also be delicious served with some vanilla ice cream or banana soft serve!


I think I still prefer the strawberry jam variety, but it is a tough call. Other votes shall be placed tonight during Hockey Night in Canada.

If you don’t hear from me tomorrow, the tornado came for my baked goods. You will come looking for me, right?

I was totally drooling over my keyboard when Ash posted these. Now I’m just drooling more.


grocery goddess jen October 26, 2010 at 5:08 pm

I’ll come looking for you AND your baked goods! We had tornado warnings here today, too, but so far so good :)


lindsay (goodiesgalore) October 26, 2010 at 5:11 pm

I’d swallow that whole pan. YUM!


[email protected] knackfornutrition October 26, 2010 at 5:12 pm

I wish I could move into your kitchen. Everything you post lately makes my stomach growl. :) I love pretty much any combination of apples and oats, so I am sure that today’s dessert tastes divine.

I’m glad you got your run in early! I had to do the same because the weatherman is calling for serious storms the rest of the week. It was unseasonably warm today in upstate NY, so I was able to run in shorts! Glorious! :)


Angela (Oh She Glows) October 26, 2010 at 5:17 pm

sounds like our weather too!
I guess with the strange heat wave comes the low pressure systems…


Lisa (bakebikeblog) October 26, 2010 at 5:17 pm

i need to get one of those little rollers!


Angela (Oh She Glows) October 26, 2010 at 5:18 pm

I will warn you though, for a couple weeks you will be rolling everything in sight.


kaila October 26, 2010 at 5:20 pm

ahhhh these look to die for! recently i have been eating the “nutrigrain like” bars from barbaras bakery (they are whole grain with no sugar added) an have been lobing how great they taste….but a homemade version would be soooo much better! thanks for the new recipe inspiration!


Camille October 26, 2010 at 5:25 pm

Oh my gosh. Dare I say that the new version looks even better than the original? Blasphemy.


stacey-healthylife October 26, 2010 at 5:28 pm

Those looks awesome. I would love them with pears next time. :)


Valerie @ City|Life|Eats October 26, 2010 at 5:28 pm

These look phenomenal :) Hope the bad weather is not too awful.


briana October 26, 2010 at 5:28 pm


I am just in love with them all :) However, I do have one question…what do you do with all of them?


Angela (Oh She Glows) October 26, 2010 at 5:30 pm

Thank you :)

Leftovers go to the freezer, gifts to friends and family, Hockey Night In Canada, Eric’s coworkers.


Charlie October 26, 2010 at 5:28 pm

I’ll come looking for your baked goods :P. I’ll have to be looking for you too if I want more ;).


Angela (Oh She Glows) October 26, 2010 at 5:32 pm

bahah I know where I stand.


Michelle (The Runner's Plate) October 26, 2010 at 5:28 pm

Wow! Tornadoes this time of year! I always have to eat the apple peelings too because I feel bad throwing them away!


Angela (Oh She Glows) October 26, 2010 at 5:32 pm

Same here!


Charlie October 26, 2010 at 5:40 pm

I eat them because I think they’re tasty!


Emma (Sweet Tooth Runner) October 26, 2010 at 5:40 pm

A tornado! That sounds exciting! I live in England and we just get strong winds-tornados are far more exciting!
Mmm those apple squares look so good! I’m adding them to my (mile long) To-Bake list, which actually consists mainly of your recipes, including the jam ones! You definitely need to publish a recipe book-it would be such a hit! :)


Heather (Heather's Dish) October 26, 2010 at 5:43 pm

YOM! these are so adaptable and so BEAUTIFUL!


Ashley October 26, 2010 at 5:43 pm

They look lovely! Your photos are out of control lately..amazing :) Favorite photos are the vertical apple photo w/the blue background and the bars cooling on the wire rack. YUM.


Trish @IamSucceeding October 26, 2010 at 5:47 pm

Those look amazing…and I love the little roller!! =)


Holly @ couchpotatoathlete October 26, 2010 at 5:49 pm

It is super windy here too — the whole house shakes when the wind blows! No tornado warnings here though — and I hope they stay away from you too!

Once again I am blown away by this dessert — these look delicious! And I am so jealous of your pastry roller :)


Raylene October 26, 2010 at 5:49 pm

I made them with Raspberry jam the other night…I’m glad I freeze EVERYTHING because they’re still getting eaten super fast with only me around.


Allie (Live Laugh Eat) October 26, 2010 at 5:51 pm

Yay no more arm wrestling needed….for now :)

Ice cream would be fantaaaaastic with this, I bet. [American] Thanksgiving dessert perhaps?


Erin (Travel, Eat, Repeat) October 26, 2010 at 5:53 pm

I was totally in a baking mood last week when it was chilly and grey but today it was warm and super humid. I’m not sure when it became July again…


Meaghen October 26, 2010 at 5:56 pm

I don’t know about where you are, but here in Niagara we just got a bit of rain and some wind, nothing crazy by any means!

Those strawberry bars look so good! I never really like nutri-grain bars, but yours look amazing!


chelsey @ clean eating chelsey October 26, 2010 at 6:01 pm

Those look so good! When I saw Ashley’s yesterday, I just about drooled on the computer screen. We had really bad storms in Chicago this morning – no tornado and I’m still here!!


Lauren October 26, 2010 at 6:12 pm

How can you control yourself with such amazing things like these oat squares always in the house? Oh my, these look out of this world!!


Maddie October 26, 2010 at 6:16 pm

Yum! I want to make these soon. They look fabulous :D
I hope the tornado doesn’t hit too hard.


Janae Jacobs October 26, 2010 at 6:21 pm

Pretty sure I would eat the whole pan before they made it to the freezer. Plus, I wouldn’t tell my husband about them… I am not good at sharing such amazing food! Good luck with the tornado warning.


Dee October 26, 2010 at 6:24 pm

I don’t blame you one bit for being in love with those Strawberry Oat squares. YUM-O!


Katie October 26, 2010 at 6:28 pm

Being from the midwest, I take tornadoes seriously…I hope you are okay!!!


Jessie October 26, 2010 at 6:32 pm

The strawberry oat squares are amazing! My hubby and I made them on Sunday and love them.


Erika @ Food.Fitness.Fun October 26, 2010 at 6:39 pm

Mmmm – I like apple even better than strawberry. :-) Thanks!


lisasfoods October 26, 2010 at 6:49 pm

I am constantly impressed by your baking skills, especially because I am more of a cook than a baker.

Do you make up all of your recipes from scratch, or do you often borrow ideas from others, or adapt recipes that you find?


Angela (Oh She Glows) October 26, 2010 at 7:58 pm


A bit of both…whenever I an inspired by another recipe or adapt another recipe I always give it credit underneath the title.


Jolene ([email protected]) October 26, 2010 at 6:50 pm

Those squares turned out beautifully! You are really a MASTER in the kitchen.


[email protected] October 26, 2010 at 6:51 pm

If not the tornado, it would be me that came for your baked goods. They look amazing.


Angela (Oh She Glows) October 26, 2010 at 7:58 pm

hehehe ;)


Vegyogini October 26, 2010 at 7:05 pm

I’m coveting your adorable little pastry roller!


Megan @ Healthy Hoggin' October 26, 2010 at 7:11 pm

Apple struesel topping may be the BEST thing ever. I think I’d like the apple version even better than the strawberry!!

I need to make these ASAP!! (but then I might go crazy for them, too– I don’t think these would last in my freezer for long!!) ;)


Hope October 26, 2010 at 7:12 pm

I’d come save you…and your little baked goods too!


Wei-Wei October 26, 2010 at 7:13 pm

Mmm, streusel! These look amazing. Love love love jam bars… would you just use your fingers to press it in if you didn’t have a roller?


Kelly @ Kelly Be Well October 26, 2010 at 7:16 pm

Awesome recipe! I am so excited to make this — it looks delicious


[email protected] October 26, 2010 at 7:21 pm

OMG those oatmeal squares look divine!!


Liz @ Blog is the New Black October 26, 2010 at 7:26 pm

Your photos are great- I want to make this now!


Angela @ Eat Spin Run Repeat October 26, 2010 at 7:30 pm

Even though it might not be the case, you look like the tidiest baker I have ever seen!! If I were to mix oats, cinnamon, apples and a bunch of other things in a bowl it wouldn’t look half as good as your photos!! This looks awesome! :D


Mary (What's Cookin' with Mary) October 26, 2010 at 7:35 pm

Who else thinks we need smell-o-vision ?!


Maryea @ Happy Healthy Mama October 26, 2010 at 7:44 pm

Wowza! Those look amazing. Your photos are also incredible.


Meredith Lilly October 26, 2010 at 8:03 pm

I’m so jealous you get to watch the games on Tuesday! We don’t have sportsnet or anything, so we only have Saturday games:( We live so close to the ACC that we actually hear the fog horn thingie when they score… but we don’t know what’s going on! So cruel haha.


traci October 26, 2010 at 8:04 pm

Oooo can’t wait to try this one and of course we would looking for you….where else would we get all these yummy recipes and witty little blogs from :)


Shanna October 26, 2010 at 8:29 pm

The tornado should head West and drop off baked goods to ME!


Ravenous Rowie October 26, 2010 at 8:31 pm

Those bars look divine! Hope all goes well in tornado country!


Balanced Healthy Life October 26, 2010 at 8:51 pm

Those look amazing, I think making them with fresh raspberries would be so great! Good luck with the tornado!


Krystina (Organically Me) October 26, 2010 at 8:52 pm

I seriously wish you could be my live-in baker.


sarahMTSBB October 26, 2010 at 8:54 pm

angela!!! i just made your pumpkin scones (the only changes i made were using butter, an egg, 3 TB brown sugar, and egg wash since that’s what i have and i’m not vegan) and they are AWESOME AND PERFECT AND PRETTY too!!! my coworkers are going to be so impressed and thrilled, and i baked for others without having a perfectionist meltdown which is rare yet nice. ;) they are 20x better than starbucks’. i am pretty sure i will never buy a pumpkin scone again. thanks! you are definitely meant to be a baker…


Angela (Oh She Glows) October 26, 2010 at 9:36 pm

yay! So glad it worked out. Thanks for your comment. :)


Emily October 26, 2010 at 9:24 pm

Looks super good, Ange! I like to see the fall fruits, I’m really in the fall spirit! Good luck tonight, avoid being too close to windows!!


Cara Craves... October 26, 2010 at 9:38 pm

I am a huge fan of any apple treat!
Those are beautiful!


Rebecca October 26, 2010 at 9:49 pm

The apple slice looks amazing. Do you think it is possible to make a vegan cheesecake slice?


Candice @ ChiaSeedMe October 26, 2010 at 9:51 pm

yum. these look fantastic!

Sounds like there are storms all over the place today. I’m kind of jealous…I love storms. I’ll keep my fingers crossed for you for no tornadoes though!

Have a great night Angela!


Melissa- I Never Imagined October 26, 2010 at 9:57 pm

You’re amazing! I wish I could bake-and-snap as well as you can!


Kacie (Nonexistent Colors) October 26, 2010 at 10:34 pm

Looks like a must try!!


Hillary [Nutrition Nut on the Run] October 26, 2010 at 11:09 pm

I love the hot pink & light blue theme running throughout this post :)


monicanelsonfitness October 26, 2010 at 11:32 pm

just lovely! love apples in all ways…but a crisp is my favorite.


Heidi - Apples Under My Bed October 27, 2010 at 12:54 am

These look amazing, as usual :) Love that roller. Good luck with the wild weather!
Heidi xo


Averie (LoveVeggiesAndYoga) October 27, 2010 at 1:17 am

These look awesome…I love apple crisps and crumbles of all kinds…vegan, baked, raw, you name it, I am a fan! I have a raw/no-bake apple crumble recipe that I love. Anytime one mixes oats, apples, agave or sugar, vanilla together…it’s a success :)

“I had a great 4.5 mile run in about 38 mins and a balmy 18C temperature. ”
I am such an American I couldnt tell you what 18c is. But what I can tell you…is that you’re hella fast, lady! WOW!! You are bookin’ it! Nice speed!!!



Kate October 27, 2010 at 1:43 am

Looks incredible. I love fall desserts and especially anything involving streusel.


SP October 27, 2010 at 7:06 am


You constantly amaze me with your creativity. Thanks for the cheer and joy you bring into so many of our lives!


[email protected] October 27, 2010 at 8:00 am

Those all look delicious, I love adaptable recipes like that!


Jessica October 27, 2010 at 8:24 am

I made these with fresh raspberries and LOVE them! They are crazy good ;-) Thanks for the great recipe!!


Corey @ the runner's cookie October 27, 2010 at 9:25 am

Mmmm you are making me want to make these, like tonight!! I’m daydreaming about a blueberry variety…


Allison October 27, 2010 at 2:18 pm

When i first saw you post the strawberry ones i immediately was reminded of the apple bars that my mom would make as i was a kid but unfortunately they have cream cheese in them:(:( I made these bars with a cherry filling (for my roommates boyfriend’s party) and they were good but i think that apples would be even better!!


Adventures in Veg October 28, 2010 at 4:34 am

Oh my gosh they look *ridiculously* nice!! I adore oats, apples and cinnamon together- I usually have them all in porridge! – but this dessert looks like it needs to be made immediately…


Marisa October 28, 2010 at 5:22 pm

I made the strawberry bars last night and they are to die for! I used Spelt flour for the base ant it turned out great. Your right, I need to freeze them or I will be eating the rest tonight :) Im going to make the apple burritos this weekend. Thanks for all the great recipes!


Jill October 31, 2010 at 6:32 pm

Made these today and they were really good! Also tried 2 of your cracker recipes – even the kiddo’s ate them up! Thanks for the great recipes!


Jess Culpitt November 3, 2010 at 10:38 pm

Thanks for a fabulous recipe Angela! I made these last night and we added cranberries to the apple mixture…perfect touch of tartness! I’ve been following your blog for awhile now and love your recipes and stories ~ thanks for the great recipes and good luck with the Project Food Blog!


Lynn October 20, 2013 at 10:02 am

Is there a gluten free version or can I just swap out with oat flour?
Love your recipes Angela, you are helping us get healthy!!


Allison Roderick November 24, 2013 at 10:01 pm


Wondering the same thing!
Did you try it? How did it come out?

Let me know!



Rositsa October 31, 2013 at 12:38 pm


I realize this post was published over 3 years ago but I find the recipe soo tempting to make, that I just had to ask you something. Can I substitute coconut oil or anything else for Earth Balance / butter?

Just like you, when I get inspired by a recipe, I usually adapt it to what ingredients I have or can easily find, and also to my taste. I’m planning to do the same with this recipe by using cows milk (plant milks are SO darn expensive here!), brown sugar, a flax egg (or a real one, although I really wanna try the vegan version) and probably something, say honey, instead of maple syrup — or if you have a better suggestion, I’d love to hear it :)

Thank you for the wonderful recipe! I am a great fan of oatmeal in cookies and muffins and I’m sure I’ll just love this one!


Rositsa November 23, 2013 at 5:15 am

I just wanted to say I made this .. cake (to me everything’s called a cake :)) with the tweaks I mentioned above: cows milk, a real egg, honey instead of maple syrup and coconut oil whenever the recipe called for butter/earth balance. It turned out AMAZING and my family loved it, and so did I!


Allison Roderick November 24, 2013 at 10:00 pm

Hi Angela,

I make alot of your recipes – and they aways turn out SO good. Recently I am on a gluten free diet (& have been trying alot of your gluten free recipes). Just wondering if these apple streusel oat squares have a way of becoming gluten free? Could I sub the kamut flour with another? If so what would be best?
I have a galore of gf flours in my cupoard.

Thanks so much!



Angela (Oh She Glows) November 29, 2013 at 2:16 pm

Hey Allie,

Thanks for your kind words! I’m so sorry for the delay in getting back to your comment. I kept meaning to do so, but got busy. Anyway, you might be able to replace the kamut flour for oat flour, but I haven’t tried this out so it would be an experiment! Let me know how it goes if you try it. Otherwise I will try to put it on my list of recipes to make GF. :)


Allison November 29, 2013 at 11:50 pm

I just tried doing oat flour on thanksgiving morning and they turned out wonderful! Thank you so much! :) The whole family enjoyed them!!



Brittany December 18, 2013 at 10:27 pm

I made these tonight as an edible gift for my vegan boss who also has a nut allergy. Amazing! They taste great and I can’t wait to share them with her soon!


Mady August 31, 2014 at 10:51 am

Hi Angela..made these a few days ago..followed the recipe as written

Turned out great!!! It tastes like a crumbly apple pie..mmmmm..the kamut flour definitely adds dimension to the taste of this streusel

My mom loved these as well which means they truly are a success

5 Stars !


Cate November 26, 2015 at 6:56 am

You are my hero!! I’m so glad I started following you before you become famous. It’s neat to have seen your journey.
