How to Make Peanut Butter Banana Baked Oatmeal Recipe
Step 1: Prepare Your Baking Dish
Start by prepping a 9×9 inch baking dish with either non-stick cooking spray or parchment paper. This saves you from any sticky situations later and ensures your oatmeal comes out in beautiful, intact slices.
Step 2: Preheat the Oven
Set your oven to 350 degrees Fahrenheit. While the oven warms up, you can get all your ingredients together, so everything flows smoothly once you start mixing.
Step 3: Combine Bananas and Peanut Butter
In a large bowl, add the mashed bananas and creamy peanut butter. Stir them together well until the mixture is smooth and creamy. This combo is the heart of your baked oatmeal, lending both moisture and flavor.
Step 4: Add the Sweeteners and Egg
Mix in the vanilla extract, maple syrup, brown sugar, and the egg. Be sure to stir until everything is fully combined, creating a luscious base that will hold your oats perfectly.
Step 5: Incorporate Milk, Oats, and Dry Ingredients
Next, pour in the milk, then add the rolled oats, baking powder, salt, and cinnamon. Stir everything thoroughly. The oats absorb the flavors and liquids, ensuring every bite is simply heavenly.
Step 6: Transfer to Baking Dish
Pour your oat mixture into the prepared baking dish, spreading it out evenly so it bakes consistently and forms those lovely edges we all love.
Step 7: Add Chocolate Chips on Top
Sprinkle a handful of extra semi-sweet chocolate chips on the surface. As they bake, these melt into gooey pockets of chocolate that make every bite decadent.
Step 8: Bake Until Golden
Place the dish in your preheated oven and bake for 20 to 25 minutes. You’ll know it’s done when the edges start to brown and the top springs back slightly when pressed—a sure sign that it’s cooked through but still moist inside.
Step 9: Cool and Drizzle with Peanut Butter
Let the baked oatmeal cool just a little before serving. For an extra touch of indulgence, drizzle melted peanut butter on top. This final flourish adds both visual appeal and a rich finishing flavor that’s irresistible.
How to Serve Peanut Butter Banana Baked Oatmeal Recipe
Garnishes
Enhance your serving with a sprinkle of chopped peanuts or a dusting of cinnamon to add a little crunch and an extra layer of flavor. A dollop of Greek yogurt or a drizzle of honey also pairs beautifully, balancing richness with a tangy or sweet note.
Side Dishes
This peanut butter banana baked oatmeal stands beautifully on its own, but if you’re feeling like rounding out your meal, fresh fruit such as berries or orange slices can brighten it up. A glass of cold milk or a warm herbal tea also complements the warm and cozy vibe perfectly.
Creative Ways to Present
Serve it in charming ramekins for individual portions, or cut it into squares for a crowd-pleasing breakfast buffet. You can even top slices with a scoop of vanilla ice cream for a delightful brunch or dessert twist that’ll surprise your family and friends.
Make Ahead and Storage
Storing Leftovers
Leftover Peanut Butter Banana Baked Oatmeal Recipe keeps beautifully in an airtight container in the fridge for up to 4 days. This makes it an ideal option for quick grab-and-go breakfasts during busy mornings.
Freezing
If you want to prepare ahead even more, freeze individual portions wrapped tightly in plastic wrap and foil. They will stay good for up to 2 months and thaw quickly when you’re ready to enjoy them.
Reheating
Reheat refrigerated or thawed slices in the microwave for about 30 to 60 seconds or until warm. You can also pop them in a toaster oven to revive the slightly crisp edges for an extra satisfying texture.
FAQs
Can I use natural peanut butter instead of creamy?
Absolutely! Natural peanut butter will work just fine, though it may give a slightly different texture. Stir it well before adding to make sure it’s smooth and evenly distributed in the mixture.
Is this recipe gluten-free?
Yes! Just be sure to use certified gluten-free rolled oats if you have gluten sensitivities or allergies, as oats can sometimes be cross-contaminated.
Can I substitute the egg for a vegan alternative?
For a vegan version, you could try using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or a chia egg. Keep in mind the texture might be a bit different but still delicious.
How ripe should the bananas be?
Very ripe bananas with lots of brown spots are best. They are naturally sweeter and softer, which adds great flavor and moisture to the oatmeal.
Can I add other mix-ins?
Yes! Feel free to experiment with chopped nuts, dried fruits, or even shredded coconut. Just keep in mind that large additions might change the baking time slightly.
