Ingredients
 
 

Macerated Peaches

  • 4-5 medium peaches, peeled, pitted and sliced (thawed frozen peaches work too)
  • 1 tbsp maple syrup
  • ½ tsp cinnamon
  • 1 tsp cornstarch

Baked Oats

  • 1 ¼ cups quick oats
  • ½ cup oat flour
  • ¾ tsp baking soda
  • Pinch salt
  • â…” cup vanilla protein powder
  • 2 tbsp ground flax seed
  • 1 tbsp cinnamon
  • 1 ½ cups unsweetened applesauce
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 tbsp maple syrup, optional (see Note 1)

Vanilla Protein Frosting

  • 2 tbsp milk (I use 2%, but any kind works great)
  • 2 tbsp Greek yogurt (I use fat free plain, but vanilla works too)
  • 1 tbsp plus 1 tsp vanilla protein powder
  • 1 tsp vanilla extract

Instructions
 

Macerated Peaches

  • In a medium bowl, combine the peaches, maple syrup, cinnamon and cornstarch and mix then set aside for at least 30 minutes

Baked Oats

  • Preheat oven to 350℉ and line a 9"x9" baking dish with parchment paper then set aside
  • In a large bowl, combine oats, oat flour, baking soda, salt, cinnamon, vanilla protein powder, flax, egg, vanilla extract, applesauce and maple syrup and mix until fully combined
  • Pour into the lined baking dish then smooth out
  • Top with the macerated peaches
  • Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean
  • Let cool before using the parchment paper to remove from the pan then divide into 6 slices

Vanilla Protein Frosting

  • Whisk together all ingredients until smooth – add a little more milk or yogurt if you want to adjust the thickness
  • Serve the baked oats warm or cold topped with frosting

Notes

Note 1: I don’t find the baked oats need extra sweetness because of the peaches and the frosting. If you want them a little sweeter, or if your peaches aren’t very sweet or in season, add 1-2 tbsp maple syrup to the batter.
