Why You’ll Love This Single-Serve Baked Oatmeal
- Quick and easy to make! Prep this baked oatmeal in just 5 minutes!
- A healthy breakfast made with wholesome ingredients!
- The perfect base recipe for any of your favorite toppings!
- High in fiber & protein! A healthy and nutritious way to kick off your morning!
- Taste like a healthy oatmeal cookie for breakfast!

- Overripe bananas: make sure to use bananas that have some brown spots! Using an overripe banana is going to make this oatmeal taste the yummiest! As bananas ripen, they get sweeter and more flavorful (making sweeter and more flavorful baked oats!) If you’re bananas aren’t ripe enough yet, you can ripen them in the oven.
- Oats: I really love the texture the old-fashioned rolled oats give this recipe! You can use quick oats but note that it won’t be the same texture. I would not recommend using steel cut oats for this recipe. Just make sure to use certified gluten-free oats if needed.
- Milk: any choice of milk works! Use whole milk, 2% or skim milk. You can also use almond milk, oat milk, etc. Use dairy-free milk if needed.
- Protein powder: I used PEScience vanilla (code Laurenfitfoodie to save!). If you want to use another brand of protein powder, I would recommend a similar whey + casein blend. Not all protein powders bake the same, so make sure you use a protein powder you know bakes well. You can also omit the protein powder if desired and add a little sweetener to your desired taste.
- Peanut butter: or any nut butter of choice! Try almond butter or cashew butter. You can also use sunflower butter if you have a nut allergy.
- Baking powder: make sure it’s fresh (opened within the last three months). I like to write the date on the top of the can so I can keep up with how long it’s been opened.
- Chocolate chips: I used Enjoy Life. Dark chocolate chips, semi-sweet, milk chocolate, they all work. Use dairy-free chocolate chips if needed.
- Double chocolate: use a chocolate protein powder to make this baked oatmeal a chocolate lover’s dream!
- Nuts: throw some nuts in there like pecans or almonds for additional healthy fats.
- Fresh fruit: throw in some fresh berries like strawberries, blueberries or raspberries! Or add some extra banana slices on top.
- Spice: add a little cinnamon, apple pie spice or pumpkin pie spice for a fall touch to this recipe.
How To Make
The full printable recipe is below, but let me walk you through the process so you know what to expect when you’re making it!

1. Grease a (6 or 8 oz.) ramekin or other small oven-safe dish; set aside. In a separate small bowl, mash the banana with a fork.

2. Mix in the oats, milk, protein powder, peanut butter and baking powder until well combined.

3. Transfer batter to dish. Mix in the chocolate chips, saving a few for topping, then smooth the top out. Sprinkle with remaining chocolate chips (plus a tiny pinch of salt if desired).

4. Bake in the air fryer or oven (see recipe card for times and temps for both). Carefully remove. Top with a few banana coins + drizzle of maple syrup to serve if desired and enjoy!
Helpful Tips
- Prep in advance: you can prep this oatmeal in advance if you want! Go ahead and mix all the ingredients in a small bowl and cover with plastic wrap. Store in the fridge until you are ready to bake or air fry.
- Meal prep: if you want to make a few of these for meal prep you can. Just bake as directed then store in an airtight container in the fridge. Reheat in the microwave or air fryer when you are ready to enjoy.
- Don’t overcook: make sure not to overcook! I prefer the inside to be a bit soft that’s why I recommend only baking for about half the time in the air fryer or oven then letting it continue to bake in the hot baking dish to finish cooking in the center.
- Use the right size ramekin: the oats should only go up half way to three quarters of the way up, otherwise it might overflow in the oven or air fryer.

What type of oats work best for this recipe?
I prefer using old-fashioned rolled oats for this recipe. You can use quick-cooking oats for this recipe but the texture will be slightly different. If you use old-fashioned rolled oats, it will be a little nuttier and heartier. If you use quick oats it will have a little more cake-like texture. Both will work fine and it’s just up to your preference. I would not use steel-cut oats for this recipe.
Can I prep this baked oatmeal recipe in advance?
You sure can, in fact there’s a ton of health benefits that come from soaking oats! Mix everything together, then wrap tightly in plastic wrap and store in the fridge until ready to bake or air fry the next day.
What size ramekin should I use for this recipe?
I think a 6 or 8 oz. greased ramekin dish works best! Just make sure the oats only fill it half way to three quarters of the way up, otherwise it might overflow in the oven or air fryer.
