Ingredients needed
This delicious and healthy brownie-baked oatmeal recipe is made with simple ingredients that you likely already have in your pantry and fridge. Here’s the lineup:
See a full list of ingredients and quantities in the recipe card below!
- Banana: Three mashed bananas add the perfect amount of moisture and natural sweetness. For best results, bananas with brown spots that are overly ripe.
- Eggs: You’ll need 1 egg to help the ingredients bind together and provide structure.
- Peanut butter: Crunchy or creamy peanut butter will work. I recommend a natural variety that is made with only peanuts and salt.
- Maple syrup: Pure maple syrup will naturally sweeten the baked oatmeal.
- Baking staples: To ensure this tastes delicious and bakes properly, you’ll need a vanilla extract, salt, and baking powder.
- Chocolate: For the rich chocolate flavor, we’re stirring in unsweetened cocoa powder and mini chocolate chips. Use dairy-free chocolate chips, as desired.
- Milk: I typically use 2% milk. You can use unsweetened vanilla almond milk or oat milk to keep this breakfast bake dairy-free.
- Oats: The base of this dish is made with old-fashioned rolled oats. Use gluten-free oats, if needed. However, quick oats or steel-cut oats will not provide the right texture.
How to make this baked oats recipe
This baked oatmeal recipe is super simple to mix up! You just need to stir the ingredients together in one large bowl, pour the mixture into a pan, and bake!
For full, printable instructions, reference the recipe card at the bottom of the post.
- Mix ingredients: Preheat the oven to 375 degrees F. Place the mashed bananas in a large bowl together with the egg, peanut butter, maple syrup, vanilla, salt, baking powder, and cocoa powder. Whisk until combined.
- Bake & serve: Stir in the milk and oats, then fold in the chocolate chips. Transfer the mixture to a baking dish and drizzle with extra peanut butter, if desired. Bake for 35-45 minutes. Serve with banana slices and enjoy.
Recipe Tips
- Make this vegan baked oatmeal by replacing the egg with a flax egg. Mix 2 tbsp ground flaxseed with 1/3 cup warm water in a small bowl and let sit for 5 minutes. Then add it to the oatmeal mixture. Also, be sure to use non-dairy milk and chocolate chips.
- Don’t have ripe bananas? You can easily ripen your bananas by wrapping them in foil and popping them in the oven at 350 degrees for 10 to 15 minutes.
- I love the flavor of peanut butter in this recipe, however, if you have a peanut allergy, feel free to use another nut butter or seed butter. Almond butter, cashew butter, or sunflower seed butter will all work fine.
Frequently asked questions
Baked oatmeal is very healthy and filled with great nutrition! It’s loaded with fiber, complex carbs, and whole grains. You can customize it to be higher in protein or healthy fats, depending on additions. Overall, it is a great well-balanced meal.
If these baked oats are soggy, they may have just not cooked long enough. If take them out of the oven too soon, the oatmeal will have cooked on the top, but the inside will still be gooey. Be sure to allow the baked oatmeal to cook for 35 to 45 minutes and until set. After removing from the oven, allow the oats to cool for about 10 minutes this will help them completely set.
Yes. Even though rolled oats is usually recommended, quick oats will also work. In fact, I sometimes run out of rolled oats and I end up making baked oats with quick oats and they turn out just fine. You will notice a slight difference in texture only,.
