These protein brownie bars combine rich chocolate and creamy peanut butter in a fudgy, chewy texture. Made with just five simple ingredients, they are quick to prepare and perfect for a nutritious snack or breakfast.

Ingredients

Scale
  • 1 cup (100g) chocolate protein powder (whey or plant-based)
  • 1/2 cup (125g) natural peanut butter (creamy or chunky)
  • 1/4 cup (60ml) maple syrup (or honey)
  • 2 large eggs (room temperature)
  • 2 tablespoons (15g) unsweetened cocoa powder

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, letting some overhang for easy lifting later.
  2. In a medium bowl, whisk together the eggs and maple syrup until smooth and slightly frothy, about 1-2 minutes.
  3. Add the natural peanut butter to the wet mixture. Stir using a spatula until the peanut butter blends in evenly, but do not overmix to keep swirls.
  4. In a separate bowl, sift together the chocolate protein powder and cocoa powder to prevent clumps.
  5. Gradually fold the dry ingredients into the wet mixture using gentle strokes until just combined.
  6. Pour the batter into the prepared pan and smooth the top evenly. Optionally, drizzle extra peanut butter on top and swirl with a knife for a marbled effect.
  7. Bake for 15-18 minutes. Check at 15 minutes by inserting a toothpick in the center; it should come out with a few moist crumbs but not wet batter.
  8. Remove from oven and let cool completely in the pan on a wire rack.
  9. Use the parchment paper edges to lift the bars out. Cut into 12 squares with a sharp knife.
  10. Store in an airtight container at room temperature for up to 3 days, refrigerate for up to a week, or freeze for up to 3 months.

Notes

Do not overmix the batter to avoid tough bars; folding gently preserves a chewy texture. Let peanut butter come to room temperature for easier mixing and creamy pockets. Check bars at 15 minutes to avoid overbaking. For vegan version, replace eggs with flax eggs and use plant-based protein powder, baking time may increase slightly. Adding a handful of fresh raspberries on top before baking adds a nice tang. Flaky sea salt sprinkled on top before baking enhances flavor.
