Portable Baked Oatmeal – Snack Size! Plus, 10 Other On the Go Snack Ideas


baked oatmeal-3629

Strange, yet familiar, back-to-school feelings have been making their way into my brain lately. It has been 4 years since I graduated with a master’s degree in social psychology and I’m convinced I will forever feel like a student this time of the year. Sometimes, I wish I could do it all over because I’d do things a bit differently. For starters, I wouldn’t settle for a major that I wasn’t completely in love with and secondly, I would’ve fed myself better and not beat myself up so much. I loathed my body in university and now when I look back on pictures I think, damn, why was I so hard on myself? Live and learn.

When I entered university, I wanted to become a registered dietitian, but I was lacking a few science courses. Instead of delaying university for a year (and not getting to go with friends), I decided to major in psychology even though nutrition was my true passion. Knowing my passions now, I would’ve majored in photography/food styling, culinary arts, or waited a year to pursue my RD. The thing is, I didn’t really figure out I had a passion for photography until many years later, which just goes to show that you have to figure some things out as you go. Things always have a way of working out one way or another. If you don’t get it right the first time, you certainly aren’t doomed (this took me a while to figure out).

Anyway, I came to tell you about portable snack ideas and got a bit side-tracked.

Lately, I’ve received several questions with a similar theme – what are some portable vegan snacks that I can bring to work or school? I figured it was time to put a post together on this very subject.

Here are some of my favourite portable snacks:


You can add this mini baked oatmeal to the list now too!

I love baked oatmeal and when I make it, I often find myself eating leftovers for a snack – straight from the fridge! So, I thought – why not make mini baked oatmeal purposely for on-the-go snacks? These mini mason jars (125ml/4.2 oz) are the perfect size for a snack and they won’t take up a lot of room in your bag. I picked mine up from Canadian Tire. You can find different sized mason jars at many home hardware type stores, as well as Wal-Mart.


It only takes 5-10 minutes to whip up the recipe and then it’s into the oven for 20-25 minutes. Cool completely before putting on the lid and placing in the fridge. Now you have 6 grab-and-go snacks ready for the week ahead. Well, actually, you have 5 snacks because you’ll obviously eat one right out of the oven!

Fill your mason jars like so. You want to leave some room for toppings.

After baking, you can enjoy them plain…

Or add your favourite toppings just like you would with regular oatmeal. Here I added almond butter and jam.

Other topping ideas:


Last night I also discovered this can be turned into dessert. Serve it warm with a scoop of non-dairy ice cream for a healthy dessert. Just throwing that out there.

Portable Baked Oatmeal – Snack Size!

Print, Email, or Text this recipe


  • 1 cup rolled oats (use GF oats if necessary)
  • 2 tbsp chia seed (or ground flax)
  • 1 tsp cinnamon
  • 1/4 tsp nutmeg
  • pinch of fine grain sea salt
  • 1/2 tsp baking powder
  • 1 cup almond milk
  • 1.5 tsp vanilla extract
  • 2 tbsp pure maple syrup
  • 1 peach (or other fruit like apple or banana), chopped
  • 1/3 cup walnuts or pecans (or use seeds for nut-free), chopped


1. Preheat oven to 350F. Grab 6 mini mason jars (125ml/4.2 oz) and remove lids. Alternatively, you can use 8oz jars and make 3-4 servings.

2. In a large bowl, mix together the oats, chia seed (or ground flax), cinnamon, nutmeg, salt, and baking powder.

3. Add the almond milk, vanilla, and maple syrup and stir until combined. Fold in the chopped fruit and nuts.

4. Keep stirring the mixture so some of the milk will absorb. Divide the mixture between the 6 mason jars (about 1/3 cup mixture each), leaving about 1.5 cm at the top. If any milk remains at the bottom of the bowl, divide it between the jars. Gently push the oatmeal down with your fingers.

5. Bake at 350F for 22-25 minutes on a small baking sheet, or until slightly firm and golden on top. Allow to cool completely for about an hour or longer. Add any toppings you desire, place on lid, and into the fridge.

Kathleen @ fittitude freedom August 15, 2012

You are absolutely right that you figure things out as you go. I’m 46 and much older than you and I have decided to really switch gears from a successful career in medical practice administration to going back to school full time to pursue a masters degree in nutrition. This fall will be my second full time semester obtaining all the necessary nutrition & science pre reqs that I didn’t take for my B.S. or MBA. Lots of sacrifices short term but I know long term the payoff will be huge! You have obviously discovered what you love to do sooner vs. later and your passion for what you do is beautifully shared with others everyday. I will definitely be making the portable snacks to take with me to school. Thanks for the recipe.


Angela (Oh She Glows) August 15, 2012

Congrats Kathleen! It sounds like it will be an exciting new direction for you. I’ve toyed with the idea of going back to school at some point in my future…it’s definitely never to late to learn and try something new. Goodluck with everything & keep me posted!


Alex @ Brain, Body, Because August 15, 2012

What a well-timed post! Even if I’m taking the upcoming semester off, I can always use great ideas for snacks. Thank you!


Alex @ Healthy Life Happy Wife August 15, 2012

What a great idea! I absolutely love baked oatmeal & making extra just makes sense! I could totally seeing it taste amazing with ice cream :) thanks for such a great idea!!

Love the cat tent!


Angela @ Eat Spin Run Repeat August 15, 2012

These are so freaking cute Ange!! Love all of your vegan portable snack ideas. I’m making a bunch of bars today to take with me when I travel (all the way to Toronto.. lol!) this weekend and definitely appreciate a good mess-free portable meal. Might have to do something similar to this for breakfast – or at least buy some cute mason jars hehe! :)


Danica Kordic August 15, 2012

Mason jars can go in the oven? Just wanted to make sure I am understanding that correctly before I explode my oven! lol I would do that…I suck at making things! I must try this tonight! I have all of the ingredients at home so it was meant to be!


Angela August 15, 2012

Yep :) I’ve made baked cakes-in-a-jar before and those worked fine too. I’m not sure what max heat they will tolerate, but 350F is what I’ve used in the past with no issues.


Karen August 17, 2012

What a surprising revelation…never knew that mason jars could withstand oven temps! How fun!


Karen August 17, 2012

Angela – What other grains do you think would work in baked-in-a-jar snack concoctions? How about a quinoa version?


Rachel August 15, 2012

I was just coming to your site to look up snacks! Thanks for the ideas. I’m also going to look at your other snack recipes–my parents will be in town this weekend and I want to have some healthier stuff around to munch on!


Andrea @ Vegvacious August 15, 2012

As a person who is always running late and taking breakfast on the go, I am in love with these breakies in a jar! …and they look super cute too!


Jesse (OutToLunchCreations) August 15, 2012

Great idea, I didn’t know you could put mason jars in the oven. I’m so excited to try this. I’m always on the look out for quick portable snack (and breakfast) ideas.


Laura August 15, 2012

What a great idea! Last time I tried to buy these small mason jars my bf said I already had enough mason jars (love the 1.9L and 500mL) and we had no space to store them (not that size though!), and kept giving me the “look” to put them back. I’ll sneak these in sometime soon and make this oatmeal! Sounds like a perfect mid-morning work snack.


Emily August 15, 2012

These are adorable – must try this fall!


Shannan August 15, 2012

This is just in time for my husband starting school in the fall. We are constantly trying to think of things to pack for his dinner, or snacks for him to eat!


Brenda Lynn August 15, 2012

I just saw a post like this on Pinterest. (not vegan) I make my hubby’s breakfast like this. I use 1/2 pint jars with steel cut oats mixed with a good quality slow cook oat, cinnamon, walnuts (to fil 1/2 the jar) and in the morning when he leaves I just add hot water from the tea kettle and syrup or stevia with fruit throw on the white lid. By the time he gets to work it’s all ready to go. I like the idea of adding almond butter and cooking ahead of time and having it for a snack to grab and go. Great idea! I’ll have to give this a try!


Laura @ Sprint 2 the Table August 15, 2012

I always thought it was so sill that at 18 they expect you to know what you want to be when you “grow up.” I would have gone down a totally different path. They should encourage kids to take a couple of years off exploring the world and learning about their passions.

As some one who is ALWAYS running late to work, I love this ideas! Would love to try them with mashed banana subbed for the syrup.


The Mrs @ Success Along the Weigh August 15, 2012

Yum, I’m gonna do that this weekend! Of course I immediately wanted it with pumpkin ice cream.

Gotta love an annoyed kitty shot! :-)


Christa @ Edible Balance August 15, 2012

love love LOVE this idea!! so simple… can’t wait to stock up on mason jars :)


geosomin August 15, 2012

This is a great idea. I have to eat my breakfast at work and I’m always looking for portable ideas to break up the same old…and I LOVE baked oatmeal.


Jess August 15, 2012

I am loving these! I will definitely be making these in the future!


emma August 15, 2012

This is a GREAT portable treat!
I am pregnant and looking for foods that I can easily warm up and prep early for after the baby comes…these will be PERFECT. : )


Lexi @ You, Me, & A World to See August 15, 2012

Love the idea of baked oatmeal! I always take hot oatmeal to go in mason jars too :)


Julianna @ Julianna Bananna August 15, 2012

i use little mason jars for overnight oats and smoothies all the time – love the idea of baked oatmeal in them!!


allison August 15, 2012

WHAT A great idea for my kids lunch. I can’t take glass into work for security reasons..but they can :-) mason jars can withstand lots of heat…boiling them to process when canning in rolling boil on the stove is super hot :-) make sure it’s canning jars, not recycled store jars. Just sayin’. For me for portable snacks I always make my signature green bars, containers of hummus and veggies and wholegrain crackers…and green monsters in a thermos :-)


Erica { EricaDHouse.com } August 15, 2012

Lovely idea! I haven’t seen mini mason jars yet but I’ll be on the lookout now!

I also finished my M.A. in Psychology without really thinking it through. I have dabbled with the idea of getting another degree in a health/nutrition field but I settled with obtaining my personal training license, for now!


jo @ including cake August 15, 2012

love these mini oatmeals…i can also identify with the ‘wishing you knew back then what made you tick’ as it’s only in the last couple of years that my love of photography and nutrition has really taken off also…combined with my love of being active (but that has never changed) crazy thing is my degree and job is as an architect…currently working to that change all that though :-)


Laura August 15, 2012

How do you recommend reheating these? Microwave? Oven? I’d love to make a batch and have these for breakfast every morning. Great idea, by the way :)


Angela (Oh She Glows) August 15, 2012

You could probably reheat them either way. I don’t bother, but I cant see why it wouldnt work! Just be sure not to dry them out so maybe bake them for a couple mins less.


Allie August 15, 2012

Ooh, this looks good!
Quick question: I have celiac and I react to GF oats… do you know of a substitution that will hold together like oats do? I’ve been waiting to make trail mix, but can’t seem to find a good alternative…. TY :).


Jo April 2, 2013

Have you tried barley, or quinoa flakes?


Debra November 19, 2014

Celiacs can’t eat barley, which also contains gluten either. Quinoa flakes would work.


Kayla Moothart August 15, 2012

This looks perfect! It will be the perfect afternoon snack between work and dinner!


Jennifer August 15, 2012

Mmmm, that looks great! What a good idea and addition to my lunchbox! And now my cats are demanding tents of their own.


Teri August 15, 2012

What about freezing them in the mason jars, recommended? if yes, would you freeze before or after baking? Great, great idea~


Angela (Oh She Glows) August 15, 2012

I was wondering the same thing. I just popped a couple into the freezer (cooked) so I’ll see how that goes and update the recipe in a week or so. I can’t imagine it will be a problem.


Averie @ Averie Cooks August 15, 2012

Food in jars is just automatically cuter – therefore it tastes better :)

And totally convenient, too! Score! And in snack size, not massive jumbo huge bowl size, which is perfect for 5 year olds as well as moms. :)


Layla August 27, 2012

Haha totally! As much as I’m almost a minimalist, I think I’m going to break my rule… as a bit of an organization junkie, I think the promise of lining up identical-sized jars in my fridge may just be enough to overcome my laziness when it comes to packing lunches.


Liz August 15, 2012

I majored in English because I didn’t know what I wanted to do. When I graduated, I thought I wanted a MA in psychology but decided to wait. In 1.5 weeks, I start the (long) journey to take all my science classes and get my MS in nutrition in like, a million years. My mom went back to school at 42 to get her masters in counseling – it’s never too late!!


Angela (Oh She Glows) August 15, 2012

Totally agree! Congrats to you both! I’ve toyed with the idea of going back to school to get another degree sometime. We’ll see! Life has many twists and turns…


Liz August 15, 2012

oops – actually she had me at 42 – she went back to school at 46 – plenty of time!


Tiff @ Love Sweat and Beers August 15, 2012

Brilliant. :) This sounds like a great change from my typical go-to snacks.


Tamara August 15, 2012

I can’t wait to make these! Do you know how long they will keep in the fridge? They don’t look too freezer friendly but if they are…let me know!
Tamara :)


Andrea August 15, 2012

This is great! I’m continuing on with my PhD programme in September and this will be great! Thanks!


Lisa @ the raw serenity August 15, 2012

These Look awesome!
The problem I have with most snack ideas ( such as hunmus) are that the majority of me need to be refrigerated.
So if your a student or traveling that can be very difficult.
I sometimes take an ice brick but they also take up a lot of room and are also quite heavy.
Love the idea of baked oatmeal for a snack though!


Emily @ www.main-eats.com August 15, 2012

I really wish we could go to college/university later in life! It is cruel to expect teenagers to decide what they want to do the rest of their lives! I’m 26 and still trying to figure it out! : )
That oatmeal looks great and perfect as a snack to bring to work. I’m a teacher so school is officially in session!


Sonal August 15, 2012

How cute are these oatmeal snacks!! :) What a wonderful idea, i just have to find mini jars like the ones you have. You know I think snacks are actually the hardest “meals” for me because aside from carrot/ bell pepper sticks and fruit, i don’t take anything else out. Will definitely try this :)


summertimedaffodily August 15, 2012

These are so adorable! I can’t wait to try them when I head back to college this weekend. :)

It’s so strange to be in this phase of life. Although I’m supposed to already have my future career all figured out (according to supervisors and job recruiters), there are a lot of days when I wonder if I’m truly passionate about what I’m doing…and, to that effect, if I’m not passionate about this, then what else? Where does a hobby end and a job begin? haha
Let’s chalk that one up to living and learning I suppose.

Anyway, thanks again for the recipe! :)


Melissa@American Girl in Jordan August 15, 2012

I have a degree in Geology and I hate working outside. Brilliant, huh? And this is after I changed majors about 6 times. If only we could turn back time……….

By the way, I love the site. I am steadily reading through all your past posts. Very fun and informative.


Balancing Sylvia August 15, 2012

I’ve been getting busier and busier lately and have actually found myself skipping breakfast in favor of more sleep. It’s terrible I know! Thanks so much for this idea though. It’s fantastic!
