Ingredients
  

  • Protein powder: 1 cup (whey or plant-based; chocolate or vanilla both work)
  • Rolled oats: 1 cup, blended into oat flour (or use store-bought oat flour)
  • Unsweetened cocoa powder: 1/3 cup
  • Baking powder:1 teaspoon
  • Fine salt: 1/4 teaspoon
  • Eggs: 2 large (room temperature)
  • Greek yogurt: 3/4 cup (2% or nonfat; dairy-free yogurt also works)
  • Milk: 1/2 cup (dairy or unsweetened almond/oat milk)
  • Nut or seed butter: 1/3 cup (peanut, almond, cashew, or sunflower seed)
  • Maple syrup or honey: 1/3 to 1/2 cup, to taste
  • Vanilla extract: 2 teaspoons
  • Dark chocolate chips or chopped dark chocolate: 1/2 cup (optional but great)
  • Chia or flax seeds: 2 tablespoons (optional for extra fiber)
  • Cooking spray or parchment: for lining the pan

Method
 

  1. Heat the oven: Set to 350°F (175°C). Line an 8x8-inch baking pan with parchment, leaving overhang for easy lifting. Lightly grease the sides.
  2. Make the oat flour: If using rolled oats, blend them in a blender or food processor until they become a fine flour. Measure after blending to get 1 cup.
  3. Whisk dry ingredients: In a large bowl, whisk protein powder, oat flour, cocoa powder, baking powder, and salt until no clumps remain.
  4. Mix wet ingredients: In a separate bowl, whisk eggs, Greek yogurt, milk, nut/seed butter, maple syrup or honey, and vanilla until smooth.
  5. Combine: Pour the wet mix into the dry mix. Stir with a spatula until just combined. The batter should be thick but spreadable. If it looks dry, add 1–2 tablespoons milk.
  6. Add-ins: Fold in chocolate chips and seeds if using. Save a few chips for the top.
  7. Spread and top: Scrape batter into the pan and smooth the top. Sprinkle remaining chocolate chips.
  8. Bake: Bake 18–24 minutes. Start checking at 18 minutes. A toothpick should come out with a few moist crumbs, not wet batter. Do not overbake.
  9. Cool: Let the brownies cool in the pan for at least 20–30 minutes. Lift out with parchment and slice into 9–12 squares.
  10. Serve: Enjoy warm or at room temp. For breakfast, pair with berries and a splash of milk or a dollop of yogurt.
