Calories per serving: 277 kcal
  • 1 3/4 cup rolled oats (140 grams)
  • 1 1/2 scoops PE Science vanilla plant protein (42 grams)
  • 2/3 cup unsweetened applesauce (163 grams)
  • 1/4 cup light brown sugar (48 grams)
  • 1/4 cup Skippy Natural Peanut Butter, melted (64 grams)
  • 1 egg, beaten
  • 1 egg yolk, beaten
  • 1 tsp cinnamon
  • 1 tsp vanilla extract
  • 1/4 tsp salt
  • 2 cups blueberries (297 grams)
  • 2 tbsp sugar (24 grams)
  • 1 1/2 tbsp cornstarch (15 grams)
  • 1 1/2 tbsp warm water
  • 1/2 tbsp lemon zest
Crumble Topping
  • 1/2 cup rolled oats (40 grams)
  • 1/4 cup light brown sugar (48 grams)
  • 1/4 cup white whole wheat flour (32 grams)
  • 3 tbsp unsalted butter, cold and cubed (43 grams)
  • 1/4 tsp cinnamon
  1. Pre-heat oven to 350 degrees. Line an 8x8 inch baking dish with parchment paper and set aside.

  2. Whisk cornstarch into warm water and set aside.

  3. Make the blueberry filling: Add blueberries, sugar, and lemon zest to a pot and bring to a simmer over medium heat. Once blueberries have begun to burst, bring to a quick boil for 1 minute and remove from heat. Whisk in cornstarch slurry and set aside to cool and thicken.

  4. Make the crust: Stir applesauce, melted peanut butter, 1/4 cup light brown sugar, beaten egg, vanilla, and salt together in a medium bowl. Add rolled oats, protein powder, and cinnamon and stir until everything is combined. Press the mixture evenly into the prepared baking pan.

  5. Pour blueberry mixture over the crust and spread evenly. Set aside.

  6. Make the topping: Cut in the chilled butter into the flour with a pastry cutter or food processor (or even with your hands) until the mixture resembles coarse crumbs. Mix in the oats, brown sugar, and cinnamon.  Sprinkle the crumble over the filling.

  7. Bake for 35-40 minutes or until the top is golden brown.
