Peanut Butter Banana Baked Oatmeal

2026-04-29

Peanut butter banana baked oatmeal is an easy make-ahead breakfast that slices neatly and reheats well. It tastes comforting but not overly sweet, making it useful for busy mornings or afternoon snacks. Serves 6.

Ingredients:

  • 2 ripe bananas, mashed
  • 2 cups old-fashioned oats
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine salt
  • 1 3/4 cups milk
  • 2 eggs
  • 1/3 cup peanut butter
  • 1/4 cup maple syrup or honey
  • 1 teaspoon vanilla extract
  • 1/4 cup chopped walnuts or chocolate chips, optional

Instructions:

  1. Heat oven to 375°F. Grease an 8-inch square baking dish.
  2. In a large bowl, stir together oats, baking powder, cinnamon, and salt.
  3. In another bowl, whisk the mashed bananas, milk, eggs, peanut butter, maple syrup, and vanilla until smooth.
  4. Pour the wet mixture into the oats and stir well. Fold in walnuts or chocolate chips if using.
  5. Spread in the baking dish and bake 35 to 40 minutes until set and lightly golden.
  6. Cool 10 minutes before slicing and serving.

Why it works: Banana provides natural sweetness and moisture, while peanut butter makes the oatmeal feel more filling. The texture lands between oatmeal and a soft breakfast bar.

Timing: Prep 10 minutes, bake 40 minutes, cool 10 minutes.

Store leftovers in the refrigerator and warm individual portions with a splash of milk if you like a softer texture.
