Ingredients You’ll Need

Here’s everything you’ll need for this Peanut Butter Banana Baked Oatmeal:

• 2 cups rolled oats (old-fashioned is best)
• 2–3 ripe bananas, mashed
• ½ cup creamy peanut butter
• 1½ cups milk (dairy or plant-based)
• 2 tablespoons maple syrup (optional sweetener)
• 1 teaspoon baking powder
• 1 teaspoon cinnamon
• ¼ teaspoon salt
• 1 large egg
• 1 teaspoon vanilla extract (optional)

You can also customize with add-ins like chocolate chips, nuts, or sliced bananas on top before baking.

Ingredient Notes and Variations

Using very ripe bananas is key—they’re sweeter and blend into the oats smoothly. Old-fashioned rolled oats give the best texture, but you can use quick oats if that’s what you have. For dairy-free or vegan versions, substitute almond milk and use a flax egg in place of the egg.

If you want a twist on flavor, try adding a bit of ground nutmeg or even a handful of blueberries for fruitier notes.

Kitchen Equipment You’ll Need

• Spatula

Step-by-Step Preparation: How to Make Peanut Butter Banana Baked Oatmeal

Step 1: Preheat your oven to 350°F (175°C) and grease a baking dish.

Step 2: In a large bowl, mash the ripe bananas until smooth.

Step 3: Add the peanut butter, milk, egg, maple syrup, and vanilla extract if using, and stir until well combined.

Step 4: Add the oats, baking powder, cinnamon, and salt to the wet ingredients and stir until everything is evenly mixed.

Step 5: Pour the mixture into the prepared baking dish and spread it out evenly.

Step 6: Bake for about 30–40 minutes, or until the oatmeal sets and the top is lightly golden. It should spring back lightly to the touch.

Step 7: Remove from oven and let cool slightly before slicing and serving.

Pro Tips for the Best Peanut Butter Banana Baked Oatmeal

Letting the bake cool for 10 minutes after removing it from the oven helps it set so portions hold their shape. Adding sliced bananas or a swirl of extra peanut butter on top adds flavor and visual appeal. For an even softer texture, cover the dish with foil during the first half of baking.

Common Mistakes to Avoid

A common misstep is overbaking, which can dry out the dish. Keep an eye on the edges—the oatmeal is done when the center is set but still slightly moist. Another mistake is using under-ripe bananas, which won’t provide enough sweetness or moisture.

Serving Suggestions

Serve warm with a drizzle of extra peanut butter, a sprinkle of cinnamon, or even a scoop of yogurt. Pair it with fruit on the side—fresh strawberries or sliced apples make a nice contrast. If you like hearty breakfasts, try serving it alongside savory dishes like Loaded Breakfast Hash for a brunch spread.

Creative Presentation Ideas

Cut the baked oatmeal into squares and serve on a wooden board for a brunch crowd, or plate individual servings with banana slices and chopped nuts on top. For kids, fun shapes or cookie-cutter cutouts make breakfast extra exciting.

Flavor Variations and Add-Ins

Add chocolate chips for a sweet treat, or stir in chopped walnuts for extra crunch. For a protein boost, add a scoop of protein powder to the wet ingredients—just add a bit more milk if needed.

How to Store and Reheat

Store leftovers in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave or oven until warm. You can also freeze portions for up to 3 months—just wrap slices individually and thaw before heating. Feel Good Foodie
