Cook Peanut Butter Banana Baked Oatmeal Like This

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your Peanut Butter Banana Baked Oatmeal bakes evenly and comes out perfectly cooked.
Step 2: Combine Dry Ingredients
In a large mixing bowl, combine the old-fashioned oats, baking powder, ground cinnamon, and salt. Whisk these together until they are well mixed.
Step 3: Prepare Wet Ingredients
In another bowl, mash the ripe bananas until smooth. Add the creamy peanut butter, honey, egg, almond milk, and vanilla extract. Whisk these ingredients together until fully combined and creamy.
Step 4: Mix It All Together
Pour the wet mixture into the bowl with the dry ingredients. Stir gently with a spatula until just combined. Be careful not to over-mix; you want to maintain the texture of the oats.
Step 5: Transfer to Baking Dish
Grease your baking dish lightly with cooking spray or a bit of oil. Pour the oatmeal mixture into the prepared dish, spreading it evenly.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Step 7: Serve
Once baked, allow the oatmeal to cool for a few minutes. Cut into squares and serve warm, topped with banana slices, a drizzle of peanut butter, and a touch of honey if desired.
Fit It to Your Goals
