Ingredients
Please see recipe card below for exact quantities.
- Rolled oats - the base of our recipe. I recommend using old-fashioned rolled oats for a delicious soft and chewy texture, but you can also use quick oats if you prefer.
- Milk - I prefer using unsweetened almond milk, but you can use whatever milk you like.
- Egg - this can also be easily substituted for a flax egg if you prefer to make this Vegan (see notes below on how to make it!).
- Maple syrup - this recipe isn't overly sweet, but you can adjust the amount or type of sweetener you use based on your preferences. Honey or agave work well here too.
- Vanilla extract - for a splash of vanilla flavour.
- Baking powder - to help our oatmeal cups rise and expand.
- Ground cinnamon - for a hint of spice.
- Salt - to help bring out the flavours.

Add-Ins and Toppings
You can customize this with all sorts of add-ins and toppings.
- Fresh fruits - some of my favourites are berries, sliced bananas, or diced apple.
- Purees and jams - you can mix in applesauce, mash fruit into a puree, or fruit jams and preserves if you like!
- Chocolate chips - deliciously melted chocolate chips straight out of the oven.
- Nuts & seeds - whether you like pecans, walnuts, or chia seeds, nuts and seeds are a great source of healthy fats and nutrients.
- Spices and powders - add a little spice with some cinnamon, or make it chocolatey with cocoa powder!
- Nut (or seed) butters - I love using natural peanut butter or almond butter. Sunflower seed butter is also a great nut-free alternative.
Instructions

STEP 1: In a bowl, mix together dry ingredients.

STEP 2: Into a separate bowl, mix together wet ingredients with a whisk.

STEP 3: Add dry ingredients to wet ingredients, and stir until well combined.

STEP 4: Add in your favourite mix-ins, and fold them into the batter.

STEP 5: Grease a 6-cup muffin tin with cooking spray (or use silicone liners). Evenly distribute batter into each muffin cup.

STEP 6: Pre-heat oven at 350°F/177°C, then bake for 25 minutes or until cooked.
Alternatively, pre-heat air fryer at 330°F/165°C, then bake for 12-15 minutes or until cooked.

STEP 7: When done, take it out and check for doneness with a toothpick. If batter sticks to the toothpick, cook for another 2-3 minutes. Let it cool down for a few minutes, then enjoy!

Equipment
You'll need either an oven or air fryer to bake these oatmeal cups. I personally love using my Cosori air fryer, or Breville Smart Oven for this recipe and almost all of my baking needs. They heat up quickly, cook evenly, and have been super consistent in its baking and cooking results. I also use a 6-cup muffin tin for baking, which fits perfectly into my Smart Oven; but you can also use silicone liners, which easily fit into either a muffin tin or an air fryer. The ones I use are from the brand Oxo, which have convenient pull-tabs that make the oatmeal cups easy to remove.
Meal Prep and Storage
These oatmeal cups are perfect for meal prep. You can store these away an an air-tight container in the refrigerator for up to a week, or in the freezer for up to 3 months. My go-to storage containers for meal prep are these Rubbermaid containers, which come in a set of many different sizes that make meal prep a breeze.

Toasty's Tips
- Customize these oatmeal cups with your favourite ingredients (see the 'Add-ins and Toppings' section above for ideas). You can easily adapt the flavour and nutritional profile of these oatmeal cups this way!
- For an easy substitute for the egg, you can use a flax egg instead (see below for more details!).
- Increase the batch size: While this recipe makes 6 oatmeal cups at a time, you can easily batch prep a larger amount at once (i.e. if you use a 12-cup muffin tray, simply double the ingredients in the recipe).
- Add protein powder for an easy nutritional boost of protein. I can typically add in a scoop of protein powder to this recipe without the need to add in any extra liquid; however if you plan to use more, you may want to add an extra splash of milk to offset the dryness from the added powder.
- Adjust the sweetener to your tastes - please note that this recipe is not overly sweet; if you wish to make it sweeter, simply adjust the amount of sweetener (maple syrup, honey, etc.) to your liking. You can also use fruits (mashed ripened banana), dried fruits (raisins), chocolate chips, coconut flakes, or other sweet ingredients as another way to sweeten your oatmeal cups.

FAQ
My baked oatmeal cups seem undercooked. What do I do?
Please note that each oven and air fryer is unique, so cooking times may differ based on your equipment. To check for doneness, insert a toothpick into the center of the baked oatmeal cup—if it comes out clean, it's ready! If batter clings to the toothpick, allow it to bake for an additional 2 minutes before testing again.
I'm vegan. Do I have to use the egg?
No problem! A "flax egg" serves as an excellent vegan alternative to regular eggs. Simply combine 1 tablespoon of ground flaxseed with 3 tablespoons of water in a small bowl. This mixture will substitute for the moisture typically provided by one large regular egg.
