These brown sugar cinnamon oatmeal cups are just the thing to make when you want a simple breakfast or afternoon snack. The recipe is easy to assemble and yields 24 mini oatmeal cups.
If you haven’t noticed, oats are a staple I use for all sorts of breakfasts like Blueberry Baked Oatmeal or Bananas Foster Overnight Oats. They make a healthy (and tasty!) way to fill up and start your day.

Each ½-cup serving of rolled oats provides a good source of fiber and important vitamins and minerals our bodies need. Their versatility allows me to increase nutrition to the meals my family already enjoys, including in the form of these soft mini muffin bites! More about the health benefits of oatmeal here.
Ingredients
The combination of toasty oats, cinnamon, and brown sugar is the best type of aromatherapy. Knowing that these warm delicious oatmeal bites are coming out of the oven is just the motivation I need to get the day started.
Here’s everything you need to make them:
- Old-fashioned rolled oats- the real MVP of this recipe and others
- Baking powder- to give the oatmeal cups a “lift”
- Salt- reacts with the baking poweder and counteracts the sweetness from the brown sugar
- Milk- use any of your favorite non-dairy alternatives instead
- Eggs- binds all the ingredients and makes these cups “muffin-like”
- Vanilla extract- flavor
- Brown sugar- more flavor and goes deliciously with the cinnamon
- Cinnamon- brown sugar’s best friend
Opting for incredibly easy and satisfying recipes, like these oatmeal cups, that can be prepared the night before and packed into a zip bag are a great option. They also help us get more whole grains into our day.

Swaps and Substitutions
If you want to make this recipe dairy-free, swap the regular milk for your favorite non-dairy alternatives like unsweetened almond, cashew, soy, or oat milk.
Brown sugar is optional if you’re looking to reduce sugar, but you don’t need much. Just a sprinkle over the tops of the oatmeal cups is enough to sweeten.
And just like regular oatmeal, you can customize this recipe with your favorite add-ins and flavors:
- Berries- any variety
- Diced apple
- Dried raisins
- Dried cranberries
- Chopped walnuts, pecans, or almonds
- Pumpkin pureé
- Mini chocolate chips
- Maple syrup or honey
Sometimes, I like stirring in raisins, cinnamon, and maple syrup into the batter. It tastes like my oatmeal raisin cookie dough bites.

Can you Freeze Oatmeal Cups
Of course! Once the oatmeal cups are completely cooled, place them inside a freezer bag and freeze for up to 2 months. When you’re ready to eat, remove them from the freezer and warm them in a toaster oven or microwave!
Or, if you’re packing these for lunch, pack the frozen cups in a snack box, and by lunchtime, they’ll be room temperature.
I also love offering these mini bites as an after-school snack. They’re easy to grab, rewarm and enjoy while getting started on homework.

Making Oatmeal Cups without a Muffin Pan
Yes, you can! Pour the oat mixture into a greased 9 x 13-inch pan, sprinkle on the brown sugar, and bake for 25 to 30 minutes or until the oats are set! Slice the baked oatmeal into 24 small squares, and you’re good to go.
Speaking of muffins, if you aren’t in an oatmeal mood, but still want to start your day with the delicious flavor of cinnamon and brown sugar make sure to try my coffee cake muffins!

My daughter loved these! They were a bit runny and a few overflowed… but tasted just great! They do have an eggy flavour though, I must cut down to just one egg next time.
