Instructions

Preheat the oven to 350F. Grease and line a 1 lb loaf pan with parchment paper for easy removal.
In a large bowl, mash the ripe bananas with a fork until mostly smooth with a few small lumps. Add in egg with the vanilla extract and stir to combine.
1 cup mashed bananas, 2 large egg, 2 teaspoon vanilla extract
Add the melted butter and sourdough discard and both sugars to the banana mixture. Mix until smooth.
½ cup unsalted butter, ½ cup sourdough discard, ½ cup packed brown sugar, ⅓ cup granulated sugar
In a separate bowl, whisk together the flour, baking powder and salt. Ensure everything is evenly distributed.
1 ¾ cup all purpose flour, 2 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix, the batter will be slightly lumpy.
Pour the batter into the prepared loaf pan and smooth the top. Bake for 50–60 minutes, or until a skewer inserted into the center comes out clean.
While the bread is still warm, brush the top with honey or maple syrup for a shiny, sweet finish.
1 tablespoon honey or maple syrup
Let the banana bread cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before slicing.
