Banana Bread Brownies Recipe

Introduction

Banana Bread Brownies combine the best of two beloved treats into one decadent dessert. These rich, fudgy brownies swirled with sweet, ripe banana batter create a perfect balance of chocolate and fruit. They’re easy to make and sure to satisfy your cravings.

A square chocolate brownie loaf is partially cut into smaller squares and placed on white parchment paper over a white marbled surface. The brownies have two visible layers: a dark, dense, fudgy chocolate base with a moist texture, and a lighter, tan-brown top layer with melted chocolate chunks and bits of banana showing through, giving a marbled effect. The surface looks slightly shiny with small cracks, showing gooey melted chocolate. A silver knife lies behind the brownies on the parchment. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

  • ¾ cup (3¾oz/105g) all-purpose flour
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup (4oz/115g) butter, melted
  • 1 ½ cups (12oz/340g) granulated sugar
  • 3 large eggs, at room temperature
  • 2 teaspoons vanilla extract
  • ½ cup (2oz/57g) unsweetened cocoa powder
  • ½ cup (3oz/85g) bittersweet chocolate, finely chopped
  • 2 large (10oz/284g) very ripe bananas, mashed

Instructions

  1. Step 1: Preheat the oven to 350°F (180°C). Butter and line an 8×8-inch (20x20cm) baking pan with parchment paper. Set aside.
  2. Step 2: In a medium mixing bowl, combine the flour, baking powder, and salt.
  3. Step 3: In a separate bowl, whisk together the melted butter, sugar, eggs, and vanilla extract until smooth.
  4. Step 4: Stir the dry ingredients into the wet mixture, then divide the batter evenly into two separate bowls.
  5. Step 5: In one bowl, sift in the cocoa powder and stir in the chopped bittersweet chocolate.
  6. Step 6: In the other bowl, fold in the mashed bananas.
  7. Step 7: Dollop the chocolate brownie batter into the prepared pan, then pour over the banana batter.
  8. Step 8: Use a butter knife to swirl the chocolate batter through the banana batter, creating a marbled effect without fully mixing.
  9. Step 9: Bake for 40-45 minutes, until a wooden skewer inserted into the center comes out clean. Let cool completely before cutting into squares.

Tips & Variations

  • For extra texture, add chopped nuts like walnuts or pecans to the brownie batter before swirling.
  • Use very ripe bananas with lots of brown spots for the best natural sweetness and flavor.
  • Swap bittersweet chocolate for semisweet if you prefer a sweeter brownie.
  • Try adding a pinch of cinnamon to the banana batter for a warm spice note.

Storage

Store banana bread brownies in an airtight container at room temperature for up to 3 days. For longer storage, freeze them for up to 2 months. To thaw, leave at room temperature or warm briefly in the microwave for about a minute.

FAQs

Can I use frozen bananas for this recipe?

Yes, you can use frozen bananas. Let them thaw completely and drain any excess liquid before mashing to avoid a runny batter.

Can I substitute butter with oil?

Butter adds flavor and richness, but you can substitute an equal amount of a neutral oil like canola or vegetable oil if needed. The texture will be slightly different but still delicious.

Ingredients

Scale

Dry Ingredients

  • ¾ cup (3¾oz/105g) all-purpose flour
  • ½ teaspoon baking powder
  • ½ teaspoon salt

Wet Ingredients & Others

  • ½ cup (4oz/115g) butter, melted
  • 1 ½ cups (12oz/340g) granulated sugar
  • 3 large eggs, at room temperature
  • 2 teaspoons vanilla extract
  • ½ cup (2oz/57g) unsweetened cocoa powder
  • ½ cup (3oz/85g) bittersweet chocolate, finely chopped
  • 2 large (10oz/284g) very ripe bananas, mashed

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (180°C). Butter and line an 8×8-inch (20x20cm) baking pan with parchment paper to prevent sticking and facilitate easy removal.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt to evenly distribute the leavening agent and seasoning.
  3. Combine Wet Ingredients: In a separate large bowl, whisk together the melted butter, granulated sugar, eggs, and vanilla extract until smooth and homogenous.
  4. Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Then, divide this batter evenly into two separate bowls for layering flavors.
  5. Make Chocolate Batter: Into one of the bowls, sift in the unsweetened cocoa powder and fold in the finely chopped bittersweet chocolate thoroughly to create the chocolate brownie mixture.
  6. Make Banana Batter: In the second bowl, stir in the mashed ripe bananas until evenly incorporated into the batter.
  7. Assemble Batters: Dollop the chocolate batter into the prepared baking pan first, then pour the banana batter evenly over it.
  8. Swirl Batters: Using a butter knife, gently swirl the chocolate batter into the banana batter to create an attractive marbled effect without fully blending them together.
  9. Bake: Place the pan in the preheated oven and bake for 40-45 minutes. Test doneness by inserting a wooden skewer into the center; it should come out clean or with a few moist crumbs.
  10. Cool and Serve: Remove from oven and let the brownies cool completely in the pan on a wire rack before cutting into squares for serving.
  11. Storage: Store the brownies in an airtight container at room temperature for up to 3 days, or freeze for up to 2 months. To serve, defrost at room temperature or warm briefly in the microwave.

Notes

  • Use very ripe bananas for maximum sweetness and moisture.

  • Swirling the batters lightly preserves distinct chocolate and banana flavors.
  • Make sure to check the brownies toward the end of baking to avoid overbaking and drying.
