Ingredients You’ll Need
- 2 2/3 cups over ripe mashed bananas: Bananas not only add natural sweetness but also keep the oatmeal moist. If you don’t have ripe ones, feel free to use fresh ones, but mash them well.
- 1/3 cup creamy peanut butter: This adds richness and a delightful nutty flavor. You can swap it for almond or cashew butter if needed.
- 1 cup chocolate almond milk: Offers a creamy texture and an extra chocolatey flavor. Regular almond milk works too, but it won’t be as indulgent.
- 1/4 cup maple syrup: A natural sweetener that elevates the dish. Honey or agave can be substituted here, but adjust the quantity to taste.
- 2 1/2 tsp vanilla extract: This enhances all the flavors beautifully. Use pure vanilla for the best result, but imitation will work too.
- 3 cups rolled oats: The base of this baked oatmeal, they provide fiber and heartiness. Steel-cut oats can be used, but cooking time may vary.
- 1/2 cup cocoa powder: It gives that brownie essence. Make sure to use unsweetened cocoa for balance, or use dark cocoa for a richer flavor.
- Mini-vegan chocolate chips: Add a delightful touch of sweetness. Feel free to use dairy chocolate chips or chopped chocolate if preferred.
How to Make Peanut Butter Brownie Baked Oatmeal
Preheat the Oven: Begin by preheating your oven to 350 degrees Fahrenheit. Prepare a 9 x 13 inch baking pan by spraying it with non-stick spray, so the oatmeal comes out easily later.
Mash the Bananas: In a mixing bowl, take the over ripe bananas and mash them until smooth. You’ll need about 2 2/3 cups, and the riper the banana, the sweeter your baked oatmeal will be.
Mix Wet Ingredients: Combine the mashed bananas with 1/3 cup of creamy peanut butter, 1 cup of chocolate almond milk, 1/4 cup of maple syrup, and 2 1/2 tsp of vanilla extract. Mix them well until you achieve a cohesive and creamy blend.
Add Oats and Cocoa: Next, stir in 3 cups of rolled oats and 1/2 cup of unsweetened cocoa powder. Mix everything thoroughly to ensure that the oats and cocoa are evenly distributed throughout the wet ingredients.
Transfer to the Pan: Pour the mixture into the prepared baking pan, using a spatula to spread it evenly and get it into the corners of the pan.
Sprinkle with Chocolate Chips: For an extra touch, sprinkle your desired amount of mini-vegan chocolate chips on top. This is completely subjective, so feel free to use as many or as few as you like.
Bake: Place the pan in your preheated oven and bake for 30 minutes. After that, turn the oven off but keep the pan inside for an additional 20 minutes. This step allows it to set perfectly while retaining moisture.
Cool Before Serving: Once the time is up, remove the pan from the oven and allow it to cool completely. You’ll know it’s done when the edges are golden and it feels firm to the touch.
Drizzle Optional Peanut Butter: Optional, but highly recommended — once cooled, you can drizzle some melted creamy peanut butter over the top for a finishing touch that enhances both flavor and presentation.

Storing & Reheating
Store your Peanut Butter Brownie Baked Oatmeal at room temperature for up to two days in an airtight container. For longer storage, refrigerate for about a week. If you want to freeze it, cut it into squares and store them in a freezer-safe container for up to three months. When you’re ready to enjoy, simply reheat in the microwave for 20-30 seconds. Just be aware the texture might change slightly after freezing, but you can refresh it with a drizzle of almond milk or melted peanut butter to bring some moisture back.
Chef’s Helpful Tips
- To avoid bananas from becoming too brown, consider using them quickly after purchasing.
- Ensure your peanut butter is well-mixed; if it’s too oily, your bake may turn out too dense.
- If you want a bit of crunch, consider adding chopped nuts along with the chocolate chips.
- Keep an eye on baking when you first attempt this; oven times may vary.
- If you find the texture too dense, try adding an extra splash of almond milk before baking.
- You can easily make this a make-ahead dish; just prepare the mixture the night before, store it in the fridge, and bake it fresh in the morning.
Peanut Butter Brownie Baked Oatmeal is a true joy to make and an even greater treat to enjoy. With its blend of wholesome ingredients and indulgent flavors, it’s versatile enough for breakfast, snack time, or dessert. Don’t hesitate to experiment with different nuts, fruits, or even spices to create a personalized twist.
