Step 1

Preheat the oven to 350°F. Grease a 9.25 x 5.25 x 2.75-inch loaf pan and line it with a sheet of parchment paper. There should be at least two inches of overhang on the sides to help you lift out the loaf once it’s done baking.

Step 2

In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with a hand mixer, cream together the butter and sugar. Add the lightly beaten eggs and mix just to combine. Mix in the bananas and vanilla until blended.

Step 3

In a second large bowl, sift together the flour, cocoa powder, baking soda, and salt. Add the dry ingredients to the wet and mix on medium-low speed until just incorporated. The batter will be a little lumpy, and that’s ok. Do not over mix or your loaf will be tough.

Step 4

Use a spatula to fold in 3⁄4 cup of the chocolate chips. Transfer the batter to the prepared loaf pan and sprinkle the remaining 1⁄4 cup of the chocolate chips over the top. Bake for 55 to 65 minutes, until a toothpick inserted into the center, comes out clean.

Step 5

Let the banana bread rest in the pan for 10 minutes, then gently pull up on the parchment paper to transfer the loaf to a cooling rack. Serve the banana bread at room temperature or when it is slightly warm to the touch.
