Baked Oatmeal Recipe with Peanut Butter "Frosting"

This classic baked oatmeal recipe with bananas has been a favorite for years in our house. It's super simple to mix together and pop in the oven while you get ready. An optional brown sugar broil adds a little caramelization and a peanut butter cream "frosting" has no sugar.

  • 2 cups rolled oats
  • 2 ripe bananas 1 mashed and 1 sliced
  • 1.5 cups milk of your choice
  • 1 egg beat
  • 1 tsp baking powder
  • 1/2 tsp kosher salt
  • 1 tsp vanilla
  • 1/4 tsp cinnamon
  • 1 tbsp brown sugar (optional)

For The Peanut Butter Frosting

  • 1/4 cup plain Greek yogurt
  • 2 tbsp powdered peanut butter
  • 2 tbsp milk


  • Preheat oven to 375 degrees.
  • Combine the dry ingredients in a large bowl (oats, salt, cinnamon, baking powder).
  • Combine the wet ingredients (egg, 1 mashed banana, milk, vanilla).
  • Pour the wet into the dry and mix well.
  • Spray a pie dish with cooking spray or grease with butter. Pour oat mixture in.
  • Top with sliced bananas.
  • Bake for about 26 minutes.
  • After 26 minutes, increase heat to broil, sprinkle oatmeal with 1 heaping tbsp brown sugar and broil for 3-4 minutes.

For The Peanut Butter Frosting

  • Mix yogurt, powdered peanut butter and milk until you have desired consistency. You might have to add a little more or less than the recipe calls for - just keep going until you have something you can pipe. You can also add some cane sugar if you'd like!
  • Once the frosting consistency is to your liking, scoop into a piping bag or ziplock and squeeze onto oatmeal pie.
