Step-by-Step Instructions
- Prepare Your Pan:
- Get your loaf pan ready by either rubbing it with butter and dusting with flour or lining with parchment paper so the paper sticks over the sides. This ensures easy removal and clean corners once baked.
- Mix Wet Ingredients:
- In a medium bowl combine your mashed bananas with buttermilk oil egg vanilla and brown sugar. Use a whisk and blend until everything is smooth and evenly mixed. Be sure to mash out all the banana lumps for the silkiest batter.
- Mix Dry Ingredients:
- Take a large bowl and blend together flour cocoa powder baking soda salt and espresso powder if you are using. Whisk thoroughly to break up any clumps especially in the cocoa powder.
- Combine Ingredients:
- Pour the bowl of wet ingredients into your dry ingredients all at once. Using a sturdy silicone spatula or wooden spoon gently fold everything together until just combined. Mix only until no flour is visible so the bread stays soft and tender.
- Add Chocolate Chips:
- Stir in three fourths of your chocolate chips reserving the rest for topping. Make sure the chips are evenly distributed so every slice has chocolate in every bite.
- Fill the Pan:
- Spoon the thick batter into your prepared loaf pan and use the back of your spoon or an offset spatula to level it out as much as possible. The even surface means the bread will bake up with a nice shape.
- Bake:
- Set the pan in the center of a preheated oven at three hundred fifty degrees Fahrenheit. It will need sixty five to seventy five minutes. Start checking with a toothpick at the one hour mark. It should come out clean or with a few moist crumbs but not wet batter.
- Add Topping and Cool:
- Immediately after removing from the oven sprinkle the remaining chocolate chips on the hot loaf so they melt and create a shiny topping. Wait until the bread has cooled in the pan for fifteen minutes then lift it out using the parchment or gently sift a knife around the edges if you used butter and flour.
- Slice and Serve:
- Once entirely cooled slice into thick pieces with a sharp bread knife and enjoy for breakfast or dessert.

You Must Know
My favorite part is the melted chocolate chips on top which create a glossy bakery finish. My daughter loves to eat the end piece while it is still a bit warm and the chocolate is gooey.
Storage Tips
Let your banana bread cool completely before wrapping in foil or storing in an airtight container. It keeps at room temperature up to four days but stays freshest in the refrigerator for a week. For longer storage slices or the whole loaf can be wrapped in foil and placed inside a freezer bag then frozen for up to two months. Thaw overnight at room temperature or for individual slices use the microwave for a quick treat.
Ingredient Substitutions
If you do not have buttermilk you can sour regular milk by adding a tablespoon of lemon juice or vinegar and letting it sit for five minutes. Applesauce works in place of oil for a lighter loaf but it may change the crumb slightly. Dark chocolate chunks can be swapped in for chocolate chips for bigger pockets of melted chocolate.

Serving Suggestions
This bread is delicious served as is but a little swipe of salted butter or a spread of peanut butter takes it to another level. For a dessert twist top with whipped cream or a scoop of vanilla ice cream. Toast leftover slices for a warm snack that tastes just baked.
Cultural Context
Banana bread as we know it became popular in the United States during the Great Depression when inventive home cooks found ways to use otherwise wasted overripe bananas. The chocolate version takes inspiration from American bakery classics and coffee shop treats. Adding cocoa and chocolate chips transforms a breakfast standby into an indulgent yet approachable hybrid cake that appeals to all ages.
