Ingredients You’ll Need
- 2 2/3 cups over ripe mashed bananas: These not only sweeten the dish naturally but also provide moisture for that perfect chewy texture. If you don’t have ripe bananas, you can substitute with unsweetened applesauce.
- 1/3 cup creamy peanut butter: This ingredient brings a rich flavor and creamy texture. Your favorite brand’s natural peanut butter works well, but feel free to experiment with almond butter for a twist.
- 1 cup chocolate almond milk: Adds a lovely chocolaty taste and is an excellent dairy-free alternative. You could also use regular almond milk combined with cocoa powder if that’s what you have on hand.
- 1/4 cup maple syrup: This natural sweetener enhances the overall flavor, providing just the right amount of sweetness. Honey or agave nectar can serve as good alternatives.
- 2 1/2 tsp vanilla extract: A splash of vanilla elevates the dish, rounding out all the flavors. Use pure vanilla extract for the best results; it makes a noticeable difference.
- 3 cups rolled oats: These provide the base that holds everything together. Old-fashioned oats work best here, but quick oats could also work in a pinch.
- 1/2 cup cocoa powder: This ingredient gives that decadent chocolate flavor that elevates the baked oatmeal. Be sure to use unsweetened cocoa powder for balanced sweetness.
- Mini-vegan chocolate chips: They are the fun finishing touch, adding little bursts of chocolate goodness throughout. You can use regular chocolate chips or leave them out for a lighter option.
How to Make Peanut Butter Brownie Baked Oatmeal
Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking pan with non-stick spray, ensuring your baked oatmeal won’t stick.
Mash Bananas: Take your ripe bananas and mash them until you have 2 2/3 cups of banana goodness. The riper the bananas, the better the sweetness, so don’t hesitate to use those brown-spotted beauties!
Combine Ingredients: In a large bowl, mix the mashed bananas, 1/3 cup creamy peanut butter, 1 cup chocolate almond milk, 1/4 cup maple syrup, and 2 1/2 tsp vanilla extract. Combine these ingredients until they are well-incorporated and smooth.
Add Oats and Cocoa: Stir in 3 cups rolled oats and 1/2 cup cocoa powder into the mixture. Make sure everything is evenly mixed to ensure each bite is an explosion of flavor.
Spread Mixture: Pour the luscious mixture into the prepared pan, spreading it evenly so it bakes uniformly.
Sprinkle Chips: Top your mixture with a sprinkle of mini-vegan chocolate chips, as many as your heart desires. This adds an extra layer of chocolatey goodness that melts beautifully while baking.
Bake: Place the pan in the oven and set your timer for 30 minutes. When the time’s up, turn off the oven and leave your baked oatmeal inside for an additional 20 minutes. This step helps create the perfect chewy texture.
Cool & Serve: After the full 50 minutes of baking, remove the pan from the oven. Let it cool for a bit before cutting it into squares. For a little extra flair, drizzle some melted creamy peanut butter on top after it cools.

Storing & Reheating
To store your Peanut Butter Brownie Baked Oatmeal, simply keep it at room temperature in an airtight container for up to 3 days. If you want it to last longer, pop it in the fridge, where it will stay fresh for about a week. You can also freeze it, ensuring it’s wrapped tightly in plastic wrap or in a freezer-safe container for up to 3 months. When you’re ready to enjoy, just reheat it in the microwave for about 30 seconds or until warm throughout. You may notice a slight change in texture when reheating, but a drizzle of peanut butter will rejuvenate it beautifully!

Recipe FAQs
Can I use different types of milk?
Absolutely! While chocolate almond milk gives a delicious chocolate flavor, you can substitute it with any type of milk you prefer—dairy, oat, coconut, or even regular almond milk. Just remember, if you’re using regular almond milk, consider adding a bit of cocoa powder to achieve that chocolaty richness.

Definitely! This baked oatmeal is perfect for meal prep. You can assemble it ahead of time, cover it with plastic wrap, and bake it when you’re ready. Plus, it stores well in the fridge, so making a batch for breakfast or snacks throughout the week is a fantastic idea.
Can I make any substitutions?
For sure! If you’re not a fan of peanut butter, you can substitute with almond butter or sunflower seed butter for a nut-free option. You can also replace maple syrup with honey or agave nectar if you don’t need it to be strictly vegan. And if you’re short on oats, you can use quinoa or another grain in a pinch.
Is this oatmeal gluten-free?
Yes, as long as you ensure you’re using certified gluten-free rolled oats, this Peanut Butter Brownie Baked Oatmeal is gluten-free. Just double-check any other ingredients like chocolate chips. Enjoy your delicious and trustworthy treat!
