Method

  1. Preheat the oven to 350°F (350°F) and line an 8‑inch square baking tin with parchment paper.

  2. Peel the ripe bananas and place them in a high‑speed blender.

  3. Add the eggs, cottage cheese, cocoa powder, maple syrup, baking powder, and the scoop of chocolate whey protein isolate to the blender.

  4. Blend on high until the mixture is completely smooth and no lumps remain, about 30 seconds.

    Kitchen notes · Added by ReelsMeals: Batter is completely smooth with no lumps. Scrape the blender sides if needed.

  5. Scrape the batter into a mixing bowl and give it a quick stir to ensure even distribution of the leavening agent.

  6. Pour the batter into the prepared baking tin, spreading it evenly with a spatula.

  7. Place the tin in the preheated oven and bake for 40‑45 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

  8. Remove the brownies from the oven and let them cool in the tin for 10 minutes.

  9. After the initial cooling, lift the brownies out using the parchment paper and transfer them to a wire rack.

  10. Allow the brownies to reach room temperature, then cover and refrigerate for at least 30 minutes to set the texture.

    Kitchen notes · Added by ReelsMeals: Brownies feel set after chilling. Cover before refrigerating.

  11. Cut the chilled brownies into 9 equal squares and serve.

  12. Store any leftovers in an airtight container in the refrigerator for up to 4 days.
