- 3 ripe bananas (2 mashed with the oatmeal and one sliced for the topping)

How do you make banana baked oatmeal?
You’ll start by mashing two bananas – set the remaining banana aside. You’ll slice this and use it for topping the baked oatmeal.
To the mashed banana add the eggs, honey, peanut butter, vanilla and milk. Whisk together well until all are well incorporated.
Add in the oatmeal and salt
To the wet ingredients, you’ll then stir in the oatmeal and salt.
Using a rubber scraper, pour into a prepared 9 x 9 baking dish that you’ve lightly sprayed with non-stick baking spray. I use and prefer Spectrum Non-Stick Coconut Oil Spray. Spread the oatmeal mixture evenly into the prepared pan or dish.
Toppings for peanut butter banana baked oatmeal:
Top the oatmeal with the remaining sliced banana, and the chocolate chips. I used these Enjoy Life Mega-Chunks in this peanut butter banana baked oatmeal.
The chocolate chips are certainly optional. If you would prefer to save yourself a few calories, leave these out and top with just the banana slices.
When serving, top the oatmeal with additional banana, a drizzle of nut butter. Serve alongside Greek yogurt, cottage cheese or hard-boiled eggs for added protein.
How long do you bake banana baked oatmeal?
Bake the oatmeal for 35-40 minutes. The top of the oatmeal will be golden brown and lightly toasted.
It will smell glorious and like you’re baking a fresh loaf of banana bread. If you love banana bread, be sure to check out some of my banana bread recipes: Chocolate Chip Peanut Butter Banana Bread , Purple Ribbon Banana Bread, Double Chocolate Banana Bread.
Once the baked oatmeal comes out of the oven, let cool to room temperature before slicing.
I love drizzling with some additional nut butter and heating in the microwave for a few seconds. This healthy baked oatmeal recipe is hearty, filling and the perfect way to start your day. I absolutely love this Wild Friends Cashew Super Butter.
Is peanut butter banana healthy?
Bananas paired with peanut butter is a great healthy carb and healthy fat combination. It’s good as a snack and great in this healthy baked oatmeal recipe. Note that nut butter is a calorie-dense food. A portion of nut butter is approximately 200 calories for a 2 tablespoon serving.

Old fashioned rolled oats are best for baking, as they are less-processed than quick oats. Quick oats become mushy and the texture doesn’t hold up well with the liquid ingredients. Rolled oats hold their shape and tend to reheat better.

Notes
Nutrition
Can’t wait to try this recipe but I’d do it without adding berries to the mix. Just wanted to point out a 2023 UC Davis study found that consuming bananas with berries can reduce the body’s absorption of flavanols by up to 84%. This occurs because bananas contain high levels of the enzyme polyphenol oxidase, which breaks down these specific antioxidants in berries. Unfortunately, the word isn’t out on this combo much. Cheers.
