How to Make Peanut Butter Brownie Baked Oatmeal
Step 1: Preheat Your Oven
First things first, preheat your oven to 375ºF. This way, your baked oatmeal will cook evenly and come out perfectly fluffy.
Step 2: Mix the Wet Ingredients
In a large bowl, mash the bananas until smooth. Then add the egg, peanut butter, maple syrup, vanilla extract, salt, baking powder, and cocoa powder. Whisk everything together until it’s well combined. This step is crucial because it ensures all the flavors meld beautifully.
Step 3: Add Milk and Oats
Next, stir in the milk and rolled oats until fully incorporated. Then gently fold in those delicious mini chocolate chips! This mixture should be thick yet pourable; it’s what makes our oatmeal rich and fudgy.
Step 4: Bake It Up
Transfer the mixture into a baking dish. If you’re feeling generous (and who wouldn’t be?), drizzle some extra peanut butter on top before putting it in the oven. Bake for about 35-45 minutes until it’s set and slightly firm to touch. The smell wafting through your kitchen will be heavenly!
Step 5: Serve and Enjoy!
Once done, let it cool slightly before serving. I recommend topping with banana slices for an extra treat! Enjoy your warm bowl of Peanut Butter Brownie Baked Oatmeal—it’s sure to brighten your day!
