Ingredients

  • 2 cups old fashioned rolled oats
  • 2 ripe mashed bananas about 1 cup
  • 2 cups unsweetened vanilla almond milk or other non-dairy milk
  • 1 scoop 25 grams vanilla protein powder*
  • 2 Tablespoons cashew or almond butter plus more for serving
  • 2 Tablespoons pure maple syrup
  • 1 teaspoon baking powder
  • 1/4 teaspoon cinnamon
  • Scant 1/2 teaspoon fine-grain sea salt
  • 1 1/2 teaspoons almond extract
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon butter extract optional
  • 1/4 cup sprinkles divided
  • cooking spray

Cream Cheese Frosting

  • 1/4 cup softened cream cheese
  • 2 Tablespoons plain Greek yogurt
  • 2 teaspoons maple syrup

Instructions

  • Preheat oven: Preheat the oven to 375° F and spray an 8×8 inch square baking dish with cooking spray.
  • Mix ingredients: In a large bowl, mix together the oats, banana, protein powder, almond milk, cashew butter, maple syrup, baking powder, cinnamon, salt, almond, vanilla, butter extract (if using) and 2 Tablespoons sprinkles.
  • Add to baking dish: Carefully pour oatmeal mixture into the prepared baking dish.
  • Bake: Bake for 35 to 40 minutes, until the top is nicely golden. Remove from the oven and let cool for a 10-15 minutes.
  • Make frosting: While oatmeal is baking, make the frosting if you're planning to use it. Mix together softened cream cheese and yogurt and maple syrup. 
  • Portion and serve. Top the baked oatmeal with frosting and remaining sprinkles. Drizzle each portion with additional cashew butter for serving. 
  • For storage: store baked oatmeal and frosting in separate airtight containers in the refrigerator for up to 4 days.
  • To reheat: To reheat the whole baked oatmeal (without frosting), cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set oven (or toaster oven) to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute. Once warm add icing (if using) and serve. 

Notes

  • Skip the protein powder: I like adding the vanilla protein powder for flavor and added protein, but you can leave it out if you don't want to use protein powder.
  • Make the frosting vegan: use non-dairy yogurt and vegan cream cheese.
