Healthy Chocolate Baked Oats
What's not to love about baked oatmeal? It's convenient, versatile, satisfying, wholesome, smells amazing, and reheats well throughout the week!
Inspired by the Apple Cranberry Baked Oatmeal I shared a couple of months ago, today's recipe brings together some of our favorite flavors: banana, chocolate, and peanut butter.
And I don't know about you, but I'm always happy to have another way to use up overripe bananas.
If you ever find yourself with just ONE overripe banana to use up, try these 1-Bowl Banana Oatmeal Breakfast Cookies!
You'll love this baked oats recipe because:
- it's sweetened with bananas and pure maple syrup
- prep is quick and can be done the night before
- and it's made with inexpensive, easy-to-find ingredients

Ingredient Notes

- bananas - use very ripe, fragrant bananas for the best results. They provide a lot of the moisture and sweetness.
- oats - regular, old fashioned rolled oats
- milk - any plain non-dairy milk you enjoy
- thickener - a small amount of corn starch or arrowroot helps to bind the oatmeal
- peanut butter - almond butter is also great. Make this dish nut-free with sunbutter or coconut butter.
- cocoa powder - use either regular, unsweetened cocoa or raw cacao powder
See recipe card below for amounts and full recipe.
How to Make Healthy Chocolate Baked Oats
- In a large bowl whisk the starch into the milk.
- Next add two peeled bananas to the bowl, and mash them with a fork. Add the rest of the wet ingredients plus the cocoa, cinnamon, and salt, and whisk to combine.
- Slice the other two bananas, and add one of them to the bowl along with the oats. Stir everything together.
- Pour the mixture into a 9-inch square baking dish, and arrange the remaining banana slices on top. Sprinkle with extra cinnamon, if desired, and crumble the walnuts on top.
- Bake for about 30 minutes or until hot in the center.

Toppings
My favorite way to enjoy chocolate banana baked oatmeal is with a dollop of plain vegan yogurt and a few fresh berries or additional chopped banana.
Walnuts, pecans, peanuts, hazelnuts, and almonds add awesome crunch to the soft oats. Hemp or pumpkin seeds are also delicious and add healthy fats.
If you're in the mood for a sweeter treat, you can't go wrong with a drizzle of pure maple syrup.
How to Store Leftovers
If you have some baked oatmeal leftover, store it in an airtight container in the refrigerator for up to 5 days. It reheats quickly on the stovetop or in a microwave.
Since the recipe doesn't make a huge amount I haven't actually needed to freeze any of the leftovers yet. But all of the ingredients are freezer-friendly, so it should be fine.

Amazing. I left out the maple syrup because I thought the sweetness of ripe bananas was enough for me. I also skipped the cornstarch. Used sun butter from TJ. The combo is perfect. I also love that it’s flourless. Definitely a keeper! Thank you!
