Instructions:

Preheat your oven to 350°F (180°C). Grease and line an 8x8-inch baking pan with parchment paper for easy removal.

In a large mixing bowl, whisk together the eggs and granulated sugar until well combined. Add the melted butter and mashed bananas, mixing until smooth. Stir in vanilla extract if desired.

In another bowl, combine the all-purpose flour, cocoa powder, baking powder, and salt. Mix well to guarantee even distribution of dry ingredients.

Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Be careful not to overmix.

If desired, fold in chocolate chips or nuts to the batter. Pour the mixture into the prepared baking pan, smoothing the top with a spatula.

Bake in the preheated oven for about 23-28 minutes, or until a toothpick inserted in the center comes out clean or with few crumbs. Allow to cool in the pan before transferring to a wire rack.

For the best results, make certain your bananas are very ripe for maximum sweetness and flavor.

You can also experiment with different types of chocolate chips or nuts to customize your Banana Bread Brownies. If you want a richer taste, consider adding a drizzle of brown butter glaze on top after they cool.

Store any leftovers in an airtight container in the refrigerator for up to a week or freeze them for up to three months. Enjoy your baking!
