  • Step 9: Gradually add the flour mixture, folding gently with a spatula until just combined.
  • Step 10: Line an 8×8″ pan with parchment paper, pour in the batter, and smooth the top. Bake for 40 minutes.
  • Step 11: Let the brownies cool in the pan for about 20 minutes, then lift them out using the parchment and transfer to a wire rack to cool completely.
  • Step 12: Cut into squares and serve.

Hint: Add a tablespoon or two of water to the bottom of the 8×8 pan before lining with parchment. The water helps the paper stay in place while you pour in the batter.

Recipe variations and substitute ideas

  • Sour Cream – Can be used if you prefer a slightly tangier, cake-like brownie (works well for banana bread–style brownies).
  • Peanut Butter – Add dollops of peanut butter to the batter or serve with peanut butter for a classic chocolate, banana and peanut butter combination.
  • Almond Butter – A good alternative to peanut butter for a different nutty flavor.
  • Birthday Brownies – Easily adapted into a birthday-style dessert by adding sprinkles and frosting if desired.

Equipment

  • Glass mixing bowls
  • Baking spatula
  • 8×8″ square baking pan

Ingredients

  • 1-¼ cups all-purpose flour, sifted
  • ⅓ cup cocoa powder, sifted
  • 1 teaspoon sea salt
  • ½ teaspoon baking powder
  • ¼ teaspoon espresso powder
  • 1-½ cups semi-sweet chocolate chips
  • 1 cup unsalted butter, melted and hot
  • ¾ cup light brown sugar, packed
  • 1-½ cups granulated sugar
  • 1 teaspoon vanilla extract
  • ½ cup mashed bananas (use overripe for more banana flavor)
  • 2 large eggs, room temperature

Instructions

  • Preheat oven to 350°F.
  • Sift together the flour, cocoa powder, salt, espresso powder and baking powder into a mixing bowl. Whisk to combine and set aside.
  • Place chocolate chips in a large bowl. Pour the hot melted butter over the chocolate and stir until smooth and fully melted.
  • Add the light brown sugar and granulated sugar, stirring until combined.
  • Stir in the vanilla extract, then add the mashed bananas and mix to incorporate.
  • Add the eggs one at a time, stirring gently after each addition. Avoid overmixing to prevent incorporating too much air.
  • Fold in the flour mixture a little at a time with a spatula until just combined.
  • Line an 8×8″ baking pan with parchment paper, pour in the batter, and smooth the surface. Bake for 40 minutes.
  • Remove from the oven and let sit in the pan for 20 minutes, then lift out with the parchment and transfer to a wire rack to cool completely before cutting.

Notes

Avoid overmixing the batter to keep brownies dense and fudgy; excess air can cause them to sink.

Using very ripe bananas will intensify the banana flavor and add natural sweetness.

Serve warm with a scoop of vanilla ice cream for a delightful treat.
