Ingredients for Banana Brownies

- 10 Tablespoons (141 g) unsalted butter
- 4 oz (113 g) semi-sweet chocolate, chopped
- ½ cup (50 g) natural cocoa powder
- 1 ¼ cups (250 g) granulated sugar
- ½ cup (123 g) mashed banana (about 1 large banana)
- 2 large eggs, room temperature preferred
- 1 teaspoon vanilla extract
- ½ teaspoon table salt
- ⅔ cup (83 g) all-purpose flour
- ¾ cup semi-sweet chocolate chips (reserve a few for topping)
Step-by-Step Instructions
- Preheat oven to 350°F (175°C) and line a 9×9” square baking pan with parchment paper. Set aside.
- In a large microwave-safe bowl, combine butter and chopped chocolate. Microwave in 10-second intervals, stirring well in between, until completely melted and smooth.
- Whisk in cocoa powder until smooth.
- Add sugar, mashed banana, eggs, vanilla extract, and salt. Stir until well combined.
- Mix in flour until just combined. Fold in chocolate chips, reserving a few for the top.
- Spread batter evenly into the prepared pan and scatter reserved chocolate chips on top.
- Bake on the center rack for 30-33 minutes, or until a toothpick inserted in the center comes out clean or with moist crumbs (not wet batter).
- Allow brownies to cool completely in the pan before slicing. Tip: They tend to fall apart when still warm!
Perfect Pairings: Toppings and Serving Ideas
Elevate your Banana Brownies with a dollop of whipped cream or a scoop of vanilla ice cream for a decadent treat. For a fruity twist, drizzle with caramel sauce or sprinkle with fresh banana slices. These brownies also pair wonderfully with a hot cup of coffee or a glass of cold milk.
Keep It Fresh: Storage and Reheating Tips
Store your Banana Brownies in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. To reheat, pop a slice in the microwave for 10-15 seconds for that just-baked warmth. For longer storage, wrap individual brownies in plastic wrap and freeze for up to 3 months.
Mix It Up: Recipe Variations
Try adding a handful of chopped nuts like walnuts or pecans for a crunchy texture. For a tropical twist, mix in shredded coconut or swap the chocolate chips for white chocolate. If you’re feeling adventurous, a pinch of cinnamon or a dash of espresso powder can add a unique flavor dimension.
Quick Tips for Time-Saving Success
Use a food processor to quickly mash your banana and chop the chocolate. Pre-measure all your ingredients before starting to streamline the process. If you’re in a rush, skip the chocolate chip topping and simply mix them all into the batter for equally delicious results.
