Equipment

  • 10. 5" X 7. 5" Baking Dish

Ingredients

  • 2 cups rolled old fashion oats
  • 1 cup quick oats
  • ½ cup creamy peanut butter melted
  • ⅓ cup maple syrup
  • 1½ tsp baking powder
  • ½ tsp cinnamon
  • 1 whole egg
  • ⅛ tsp salt a pinch
  • 3 small bananas
  • 1¾ cup milk
  • 1 tsp vanilla extract optional
  • non-stick cooking spray
  • sliced banana optional for topping

Instructions

  • Preheat oven to 375 F.
  • In a bowl, mash up the bananas. Then add in all the wet ingredients: milk, egg, melted peanut butter, and maple syrup.
  • In another bowl, you can mix all the dry ingredients: rolled oats, cinnamon, quick oats, salt, and baking powder. Or add them directly into the wet ingredients and mix everything together.
  • Spray a baking dish with some cooking spray and add in the oats mixture. Top with some sliced bananas if desired.
  • Bake in the oven for 35-40 minutes, or until fully cooked, when edges and top are lightly browned.
  • Remove from the oven and allow to cool for a few minutes before serving. Serve with some maple syrup and more sliced banana or drizzle melted peanut butter if desired.

Notes

  • Use a combination of rolled oats and quick oats for a lovely texture.
  • Bring the cold ingredients to room temperature for 15 minutes. 
  • Be sure that the bananas are well mashed.
  • Swap the peanut butter for your favorite nut or seed butter. 
  • Make ahead and reheat for a quick and simple breakfast. 
  • Let the baked oatmeal rest for 5-10 minutes before serving.
  • Drizzle melted peanut butter on top for a flavorful garnish. 
  • Serve with maple syrup and fresh fruit. 
  • Top with slices of banana.
