Double Chocolate Banana Bread

Step 1: Preheat the oven to 350°F. Lightly grease one 9-inch by 5-inch loaf pan and line it with a parchment paper sling.

Step 2: In a medium bowl, combine the flour, baking soda, salt, and cocoa.

Step 3: In the bowl of a stand mixer fitted with the flat beater attachment, or in a large mixing bowl using an electric hand mixer, beat the butter and sugar until light and creamy.

Step 4: Beat in the egg, then stir in the vanilla, banana, and sour cream. Scrape down the sides and bottom of the bowl to ensure all the ingredients are incorporated.

Step 5: Gently mix in the dry ingredients and chocolate chips until well incorporated.

Step 6: Pour the batter into the prepared pan and bake for 50 to 60 minutes, until a toothpick or thin knife inserted into the center comes out clean.

Step 7: Remove the bread from the oven and let it rest in the pan for 10 minutes. Turn it out onto a rack to cool completely.

Step 8: Store the bread well wrapped at room temperature for several days; freeze it for longer storage.
