How to Make Peanut Butter Banana Baked Oatmeal Recipe
Step 1: Prepare Your Baking Dish
Start by greasing a 9×9 inch baking dish with non-stick cooking spray or lining it with parchment paper. This step ensures your baked oatmeal will come out easily without any sticking, making cleanup a breeze.
Step 2: Preheat the Oven
Set your oven to 350 degrees Fahrenheit so it reaches the perfect temperature while you prepare the batter. Baking at this moderate heat allows the oatmeal to cook through evenly, developing a golden-brown crust without drying out.
Step 3: Combine the Banana and Peanut Butter
In a large bowl, mash your ripe bananas until smooth, then stir in the creamy peanut butter. Mixing these first helps distribute that luscious peanut flavor evenly, creating a rich base for your oatmeal.
Step 4: Add the Sweeteners and Egg
Next, pour in the vanilla extract, maple syrup, brown sugar, and the egg. Stir everything together until the mixture is smooth, making sure the egg is fully incorporated to help bind your oatmeal as it bakes.
Step 5: Mix in the Dry Ingredients and Milk
Now it’s time to add the milk, rolled oats, baking powder, salt, and cinnamon. Stir until all the oats are moistened and the spices are evenly distributed, giving you a thick, hearty batter ready for baking.
Step 6: Transfer to Baking Dish and Add Chocolate
Pour the oatmeal mixture into your prepared dish and spread it out evenly. Sprinkle a generous handful of chocolate chips on top—they’ll melt into gooey pockets as it bakes, adding bursts of chocolatey delight with every bite.
Step 7: Bake Until Golden and Set
Bake in your preheated oven for 20 to 25 minutes. You’ll know it’s done when the edges turn a lovely golden brown and the top springs back slightly when nudged. This perfect bake time means your oatmeal will be tender, not wet, and just firm enough to cut into squares.
Step 8: Add a Finishing Touch
After removing from the oven, let it cool just a bit, then drizzle melted peanut butter over the top for an extra layer of lusciousness. This finishing touch turns your baked oatmeal from delicious to downright irresistible.
How to Serve Peanut Butter Banana Baked Oatmeal Recipe

Garnishes
A sprinkle of chopped nuts like peanuts or walnuts adds delightful crunch that contrasts beautifully with the soft oatmeal. Fresh banana slices or a dollop of Greek yogurt can also bring freshness and creaminess to each serving.
Side Dishes
Pair your baked oatmeal with a glass of cold milk or a cup of freshly brewed coffee for a fulfilling breakfast. A side of mixed berries or a simple fruit salad provides a refreshing balance of tartness and color.
Creative Ways to Present
For a fun twist, serve the baked oatmeal warm with a scoop of vanilla ice cream or drizzle with honey and sprinkle with toasted coconut flakes. You could even turn leftovers into bars for a grab-and-go snack by cutting into squares and wrapping individually.
Make Ahead and Storage
Storing Leftovers
Leftover Peanut Butter Banana Baked Oatmeal keeps beautifully covered in the fridge for up to four days. Keep it airtight to maintain moisture and prevent it from drying out.
Freezing
If you want to enjoy this treat beyond a few days, freeze individual slices in a sealed container or freezer bag. They freeze well for up to three months and thaw quickly when you need a convenient breakfast.
Reheating
Reheat refrigerated or thawed slices in the microwave for 30 to 60 seconds until warm. You can also pop them in a toaster oven to revive that crisp edge, making the baked oatmeal taste freshly made all over again.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter adds a lovely texture contrast, giving little pops of crunch throughout the baked oatmeal.
Is it possible to make this recipe vegan?
You can make it vegan by substituting the egg with flax or chia egg and using a plant-based milk like almond or oat milk. Just be sure to choose maple syrup or another vegan sweetener.
Can I omit the chocolate chips?
Definitely! The chocolate chips add sweetness and gooeyness, but the baked oatmeal will still be delicious without them—feel free to swap them out for dried fruit or nuts if you prefer.
What’s the best way to tell when the oatmeal is done baking?
Look for golden edges and a top that springs back when gently pressed. It shouldn’t be jiggly or wet in the center; firm but still moist is the goal.
Can I add other flavors or spices?
Yes! Feel free to experiment with nutmeg, cardamom, or even a pinch of ginger to add new dimensions of flavor to the classic Peanut Butter Banana Baked Oatmeal Recipe.
