Ingredients You’ll Need
- 2 2/3 cups over ripe mashed bananas: Essential for sweetness and moisture, these bananas are the base of your oatmeal. Overripe ones are perfect as they are sweeter and creamy.
- 1/3 cup creamy peanut butter: Provides that nutty flavor and creamy texture. You can substitute with almond butter for a different taste.
- 1 cup chocolate almond milk: This adds a chocolaty twist and keeps the dish dairy-free. Regular milk or another non-dairy milk can work in a pinch.
- 1/4 cup maple syrup: For natural sweetness, a lovely alternative to refined sugars. Honey can be a substitute if you’re not strictly vegan.
- 2 1/2 tsp vanilla extract: Elevates the flavor profile with a warm aroma. Use pure vanilla extract for the best taste!
- 3 cups rolled oats: The backbone of this baked oatmeal, lending a hearty texture. Quick oats can be used but may affect the final consistency.
- 1/2 cup cocoa powder: This is what turns breakfast into a chocolate treat. Unsweetened cocoa is best to keep the sweetness in check.
- Mini vegan chocolate chips: For a delightful melty finish on top, these can easily be swapped for dairy-free options or omitted if you prefer.
How to Make Peanut Butter Brownie Baked Oatmeal
Preheat Oven: Start by preheating your oven to 350°F (175°C). This step ensures your baked oatmeal cooks evenly and achieves the perfect texture.
Mash Bananas: In a mixing bowl, mash enough over ripe bananas to measure 2 2/3 cups. Look for bananas that have plenty of brown spots. They’ll be sweeter and mix well with the other ingredients.
Combine Wet Ingredients: To the mashed bananas, add 1/3 cup creamy peanut butter, 1 cup chocolate almond milk, 1/4 cup maple syrup, and 2 1/2 teaspoons of vanilla extract. Mix well until all the ingredients are nicely incorporated, creating a smooth batter.
Add Dry Ingredients: Stir in 3 cups of rolled oats and 1/2 cup cocoa powder. Ensure everything is mixed properly; you want each oat to be coated in that rich chocolatey goodness.
Spread into Pan: Pour the mixture into a prepared 9 x 13 inch pan that you’ve sprayed with non-stick spray. Gently spread the mixture evenly so it bakes uniformly.
Add Chocolate Chips: Sprinkle mini vegan chocolate chips on top of the mixture. Use as many as your heart desires – they create that inviting, melted chocolate look.
Bake: Place the pan in the oven and bake for 30 minutes. When you check, the edges should look slightly firm, and the center should still have a bit of a jiggle.
Let Rest: After 30 minutes, turn off the oven and leave the pan inside for an additional 20 minutes. This technique allows the oatmeal to set beautifully without drying out.
Cool & Serve: Once the time is up, remove the baked oatmeal from the oven and let it cool. For an extra touch, drizzle melted creamy peanut butter on top right before serving – delicious!

Storing & Reheating
Store your Peanut Butter Brownie Baked Oatmeal in an airtight container at room temperature for up to 3 days. For longer freshness, keep it in the refrigerator, where it can last about a week. If you want to keep it even longer, freeze individual portions for up to 3 months. When ready to eat, simply reheat in the microwave for 20-30 seconds, checking until it’s warmed through. Note that while refrigeration may make it a bit firmer, a quick reheat can bring back its delightful texture.
Chef’s Helpful Tips
- To avoid mushy oatmeal, ensure your bananas are mashed well but not completely liquid.
- Double-check that your baking powder is fresh for a good rise.
- For best flavor, use room temperature ingredients like your peanut butter and almond milk.
- If you enjoy a sweeter oatmeal, consider adding a bit more maple syrup to taste.
- This dish can be made ahead, cooled, and stored for busy mornings – simply reheat individual portions!
- Feel free to get creative! Add chopped nuts, or swirl in some jam or fruit preserves for an extra flavor boost.

I encourage you to experiment – perhaps try adding in some swirl of your favorite nut butter or even throw in fresh berries. The possibilities are as vast as your creativity!

Recipe FAQs
Can I use quick oats instead of rolled oats?
Yes, you can use quick oats, but the texture will be slightly different. They may yield a softer, more pudding-like oatmeal compared to the heartier texture of rolled oats, which hold up better during baking.
How do I make this recipe gluten-free?
To make Peanut Butter Brownie Baked Oatmeal gluten-free, ensure you use certified gluten-free rolled oats. Most other ingredients are naturally gluten-free, but double-check packaging for any potential cross-contamination.
Can I substitute peanut butter with another nut butter?
Absolutely! Almond butter or cashew butter would be great alternatives, providing similar creaminess while lending a slightly different flavor profile. Just ensure your substitution doesn’t contain added sugars or other unwanted ingredients.
How can I customize the sweetness of this dish?
You can adjust the sweetness to your liking by varying the amount of maple syrup. Start with the specified 1/4 cup, then taste the mixture before baking. If you like it sweeter, feel free to add a little more maple syrup or consider using agave syrup for a vegan option.
