Keep these baked oatmeal cups in your fridge or freezer for an easy, healthy breakfast! There’s four different flavor options so you’ll never get bored. Vegan + gluten-free.
As you probably know from my countless oatmeal recipes… I’m a BIG fan of oatmeal. I love overnight oats, steel cut oatmeal, slow cooker pumpkin oatmeal, baked oatmeal, alllll the oats! Today, I wanted to focus on baked oatmeal cups! I’ve posted about baked oatmeal cups before sharing this original recipe for banana oatmeal cups and these pumpkin oatmeal cups, but I wanted to put together a full post about baked oatmeal cups because they’re pretty special and perfect for meal prep.

Here’s why:
- You can make one big batch and keep them in your fridge for a week or freezer for up to 3 months.
- They’re pre-portioned so there’s built-in portion control.
- They’re super easy to reheat in the oven, toaster oven or microwave.
- They’re super portable so you can take then on-the-go.
- The flavor combinations are endless aka you can switch things up week to week so you don’t get bored.

WATCH HOW TO MAKE BAKED OATMEAL CUPS:
How do you make oatmeal cups?
Oatmeal cups are very similar to muffins. The main difference is that oatmeal cups are flourless because you’re just using oats and they have more liquid added to the batter. In addition, muffins (especially bakery-style muffins) often have a lot of processed flour and sugar, but oatmeal cups are made with the same healthy ingredients you’d would put into a bowl of oatmeal! Huge win!
To make these oatmeal cups, you simply mix your dry ingredients in one bowl and your wet ingredients in another. Combine the two gradually and then put the batter into muffin cups. Bake 30-35 minutes at 350°F and voila… you’ve got baked oatmeal cups for the week.
You can totally just use a greased muffin tin, but highly recommend investing in silicone liners because the oatmeal cups will pop right out (no wasted oatmeal) and they are super easy to clean!

What type of oats are best for oatmeal cups?
I like to use rolled oats because they’re less processed and give a good texture to the oatmeal cups, but if you only have quick / instant oats on hand those should work fine as a substitute. I don’t recommend using steel cut oats for this recipe because the oat to liquid ratio is different and the baking time is longer. If you’re looking for ways to use steel cut oats you could try these creamy steel cut oats or this apple cinnamon baked steel cut oatmeal.
How to store baked oatmeal cups?
Store them in a sealed, air-tight container in the fridge or freezer. For freezing, I usually put them in a ziplock bag made specifically for the freezer.
How long do baked oatmeal cups last in the fridge?
Keep your baked oatmeal cups in an air-tight container in the fridge for up to a week. I usually keep what I plan to eat that week in the fridge, but if I make a double batch or don’t plan to eat them all in a week for some reason, I freeze them! Which leads me to my next question…
Can you freeze baked oatmeal cups?
You sure can! Like I said, I love to make a bunch of oatmeal cups and then freeze any I don’t plan on eating that week. I usually put them in a ziplock bag made specifically for the freezer. When you’re ready to eat them, I recommend taking them out the night before and putting them in the fridge to thaw. In the morning (or whenever you’re ready to eat, pop them in the microwave or toaster oven if you prefer to eat them warm! If you forget to thaw the oatmeal cups, you can reheat it from frozen, it will just take a little longer.

How do you reheat oatmeal cups in the oven?
You can definitely reheat your oatmeal cups in the oven, but if I’m being honest I usually just pop them into the microwave or toaster oven to reheat them!
- Oven or toaster oven: remove from liner and cut the oatmeal cup in half and heating on low (250-300°F) for 5-6 minutes or until the cup is warm throughout.
- Microwave: remove oatmeal cup from liner and wrap in a paper towel, microwave until warm throughout, about 30-60 seconds.
You can thaw the frozen cups by transferring them from the freezer to the fridge the night before or cook the oat cups directly from frozen. Just wrap the frozen cup in a paper towel and heat in 30 seconds increments until warm throughout. It should only take 1-2 minutes.
Now, onto the recipe for these baked oatmeal cups! As you might notice, each of the four flavors have a base recipe and then I add in specific ingredients to customize them. These are my top four go-to flavors and they’re all delicious — you can’t go wrong!

Notes
- Flaxseed substitutions: 2 Tablespoons of chia seeds or 2 eggs or 1/3 cup egg whites
- Honey can be subbed for maple syrup
- For storage: Store baked oatmeal cups in a sealed, air-tight container in the fridge (up to 7 days) or freezer (up to 3 months). For freezing, I usually put them in a ziplock bag made specifically for the freezer.
- To reheat: remove cup from liner and wrap in a paper towel, microwave until warm throughout, about 30-60 seconds. Or reheat in the toaster oven by cutting the cup in half and heating on low (250-300°F) for 5-6 minutes or until the cup is warm throughout. You can thaw the frozen cups by transferring them from the freezer to the fridge the night before or cook the oat cups directly from frozen.

Chocolate Chip Oatmeal Cups

Peanut Butter Banana Oatmeal Cups

Apple Cinnamon Oatmeal Cups



















I am allergic to bananas….any sub in the peanut butter ones?
You can use applesauce instead. 🙂
Made the chocolate chip muffins…. ummm… too good. Want to eat too many at a time! My only thing (and it may be a me thing) is that I think I will cut down the flaxseed a smidgen next time. Other than that… this non-cook/baker loved them. Will make the other varieties soon!
So glad these baked oatmeal cups were a hit, Shari! Thanks for making them and for coming back to leave a review. I so appreciate it!
Just about to make these (saw posting on FB). One question. You use unsweetened vanilla almond milk. Since I only have unsweetened original almond milk should I increase a sweetness somewhere else or does it not matter if almond milk isn’t flavored?
Hey Shari – It doesn’t matter and is totally a personal preference. You can add a dash of vanilla or some added sweetener if you prefer, but it’s not needed! Let me know how these turn out for you. 🙂
Does each base + toppings make 12? So, if I made each flavor- I would end up with 12 of each flavor (4 dozen)?
That’s correct!
Just made it this morning and loved them! Healthy, delicious and very easy to make.
Thank you for the recipe!
I made the chocolate chip ones last night and they turned out delicious! Thanks for the recipe!
So glad you enjoyed these, Gracie! 🙂
These are the easiest muffins and filled with high fibre, heart healthy ingredients. I always have them on hand and my little one loves them too. Again super versatile to mix up your own flavours also.
Was thinking of adding protein powder to boost the protein for my growing kiddos. Any idea how to adjust the liquid to accommodate that?
Hey Lauren! I haven’t added protein powder to these before, but someone else said that she ran out of oats and swapped in some protein powder for the extra oats, so you could always try swapping out maybe 1/2 cup of oats with protein powder and see how that turns out. Let me know what you think if you try it!!
Great receptive and thanks for all the tips! I did add 2 spoons of flour and 2 spoons of almond flour because it seemed too liquid..great as a pancake too!
I’m glad these turned out for you! The batter is definitely supposed to be more liquidy before baking. 🙂
Hi! I love baked oatmeal but hate washing muffin tins. Do you think this recipe would work to bake in a 9×13 pan?
Hey Jay! What’s your favorite baked oatmeal flavor? I have a ton of recipes for baked oatmeal that is baked in a square baking dish. Check out that link to find a flavor you like!
