Make-Ahead Peanut Butter Banana Oatmeal

To make this easy recipe ahead, bake as directed. Then, refrigerate oatmeal in an airtight container for up to 1 week.

You can also freeze individual squares for longer storage. To freeze the baked oatmeal, cool completely and cut into squares (I would not garnish with fresh banana). Wrap each piece in plastic wrap and store in an air-tight freezer container.

Substitutions for Peanut Butter Banana Baked Oatmeal

As always I get many questions about substitutions! So here are a few swaps you could make in order to ensure that this peanut butter banana baked oatmeal fits your dietary needs!

  • Quick Cooking Oats: I’ve made this recipe multiple times with both old fashioned oats and quick-cooking oats. Both work, but I really prefer the texture when using quick-cooking oats. If all you have on hand is old fashioned oats, run it through a blender or food processor for a few seconds before proceeding with the recipe.
  • Peanut Butter: Creamy peanut butter is best. But any nut butter can be substituted. 
  • Maple Syrup: Honey can be substituted if you prefer.

Baked Peanut Butter Banana Oatmeal is a healthy, make-ahead breakfast recipe that kids and adults alike love. Delicious served warm from the oven, and just as yummy as a cold afternoon snack.

Ingredients

  • 1 1/2 cups quick cooking oats
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 2 ripe bananas, mashed
  • 1/4 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1/4 cup pure maple syrup
  • 1 large egg
  • 3/4 cup milk (almond, coconut, cow)

Instructions

  1. Preheat the oven to 350°F. Spray a 9x9 inch baking pan with cooking spray and set aside.
  2. In a bowl, whisk together the oats, baking powder, salt, and cinnamon. Set aside.
  3. Mash the bananas in a large bowl and mix in the peanut butter. Continue to stir until it comes together in a batter. Stir in the vanilla, maple syrup, and egg. Once it is fully incorporated, stir in the milk.
  4. Add the oat mixture into the mashed banana mixture and stir. The batter will be very wet. Transfer to the prepared pan and bake for 25 minutes, or until the top springs back and the edges are beginning to brown.
  5. OPTIONAL: To garnish the Peanut Butter Banana Baked Oatmeal, chop one banana into small pieces and melt 1/4 cup of creamy peanut butter. Scatter the banana pieces on top of the baked oatmeal, then drizzle the melted peanut butter over the top.

Notes

Storage:

Refrigerate the Peanut Butter Banana Baked Oatmeal in an airtight container for up to 1 week.

To freeze the baked oatmeal, cool completely and cut into squares (I would not garnish with fresh banana). Wrap each piece in plastic wrap and store it in an air-tight freezer container.

Reheating:

To reheat refrigerated baked oatmeal, let it cool completely before covering with foil and storing in the refrigerator. When you're ready to serve, warm in a 325°F oven for 10 to 15 minutes, or until it's warm to the touch.

Reheat the frozen, remove the wrapping and microwave on for 30 to 60 seconds.
