Ingredients
- 1 cup ripe bananas (about 2 large), mashed

- ¾ cup light brown sugar, packed
- ¼ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ⅓ cup unsweetened cocoa powder
- ½ cup semisweet chocolate chips
- Optional: ⅓ cup chopped walnuts or pecans, for crunch
Directions
Prep Your Pan & Oven
- Preheat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal, and lightly grease.
Mix Wet Ingredients
- In a large mixing bowl, combine mashed bananas, melted butter, brown sugar, granulated sugar, egg, and vanilla extract. Whisk until smooth and well blended.
Combine Dry Ingredients
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Add the dry mix to the banana mixture and gently fold until just combined.
Make the Brownie Swirl
- Divide the batter in half. Into one half, sift in the cocoa powder and fold in the chocolate chips (and nuts, if using) to make the brownie layer.
Layer & Swirl
- Spoon alternate dollops of banana bread batter and brownie batter into the prepared pan. Use a knife to gently swirl the two batters for a marbled effect. Smooth the top.
Bake to Perfection
- Bake on the center rack for 30-35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached.
Cool & Serve
- Let cool in the pan for 15 minutes, then lift out using the parchment overhang and cool completely on a wire rack before slicing into bars.
Prep time: 15 minutes
Cook time: 30-35 minutes
Total time: 50 minutes
Notes
- Overripe bananas work best—they make the bars extra moist and sweet.
- Don't over-mix your batter once the flour is added; this keeps the bars tender.
- If you prefer a gooier texture, bake at the lower end of the recommended time.
Variations
- Peanut Butter Swirl: Add dollops of peanut butter to the top before baking and swirl for a nutty twist.
- Double Chocolate: Swap semisweet for dark chocolate chips, or add white chocolate chunks for extra indulgence.
- Gluten-Free: Use a 1:1 gluten-free flour blend in place of all-purpose flour.
