Ingredients
¾ cup unsalted butter (softened; can use salted butter but reduce salt)
1 cup granulated sugar
½ cup brown sugar (packed)
3 large eggs (room temperature)
2 tsp vanilla extract
¾ cup all-purpose flour
½ tsp salt
1 cup over-ripe mashed bananas
½ tsp baking powder
½ cup unsweetened cocoa powder
¾ cup + 2 tbsp semisweet chocolate chips (divided)
Instructions
Preheat oven to 350°F (175°C)
Line a 9×9-inch square baking pan with parchment paper, leaving overhang
Cream butter, granulated sugar, and brown sugar until light and fluffy
Add eggs one at a time with vanilla extract, beating well
Stir in flour and salt until no dry streaks remain
Fold in mashed bananas and baking powder
Divide batter into two equal parts
To one part, stir in cocoa powder and 2 tbsp chocolate chips
Spread banana batter in pan, top with cocoa-batter, and swirl with a knife
Sprinkle remaining chocolate chips on top
Bake for 45 minutes until golden
Cool completely, lift with parchment, and cut into 12 squares
Notes
Use room temperature eggs for better aeration
High-quality chocolate chips improve texture
Swirling creates an attractive marbled pattern
Let bars cool fully before cutting to prevent crumbling
