Equipment

Ingredients

  • 4 Bananas ripe (about 450–480g peeled)
  • ⅓ cup Cocoa powder
  • ⅔ cup Natural peanut butter
US Customary - Metric

Instructions

  • Prepare the pan: Preheat oven to 350°F (175°C). Line an 8-inch (20 cm) square pan with parchment paper, leaving overhang on two sides for easy removal.
  • Blend the batter: Add bananas to a food processor and blend until completely smooth. Add cocoa powder and peanut butter, then blend again until you get a thick, smooth batter.
  • Optional sweetness: Taste the batter. If you prefer sweeter brownies, add sweetener at this stage and mix again (more info in the notes section).
  • Bake: Spread batter evenly in the prepared pan. Bake for 25–30 minutes, until set in the center and a toothpick comes out mostly clean.
  • Cool & slice: Let brownies cool in the pan at least 15–20 minutes, then lift out using parchment and cut into squares. Texture improves further once fully cooled.

Notes

  • Use ripe bananas: Very ripe bananas with dark spots are essential, they provide sweetness, moisture, and better texture.
  • Cocoa powder: Use unsweetened cocoa powder. Dutch-processed cocoa gives a smoother, milder flavor, while natural cocoa gives a deeper chocolate taste.
  • Peanut butter choice: Use natural, unsweetened peanut butter (just peanuts + salt). Sweetened peanut butter makes brownies overly sweet and oily.
  • Sweetness level: These brownies are not very sweet since they rely on banana sweetness. Feel free to add 1–3 tbsp sugar, coconut sugar, maple, honey or sugar-free sweeteners and adjust to taste. 
  • Mix-in ideas: feel free to add chocolate chips or chunks, chopped nuts, dried fruits, coconut flakes and more.
  • Nut-free option: Replace peanut butter with tahini or sunflower seed butter.
  • Add protein powder: You can mix in 1–2 tablespoons chocolate or vanilla protein powder. If batter becomes thick, add 1–2 tbsp milk or water.
  • Storage: 
    • Room temperature: up to 1 day
    • Refrigerator: 4–5 days
    • Freezer: up to 2 months, well wrapped
