Marbled Banana Bread


I had some ripe bananas on my counter today. You know, the ones that are so dark and so ripe that you can smell them from the back yard? Yeah, those suckers had to go. I knew I was going to make banana bread, but I wanted to do something a little different. Enter….Marbled Banana Bread.

I know, I know…this bread looks fancy. Like it’s going to take lots of bowls and different mixes. But I promise it’s so easy! It’s literally as easy as making the banana bread batter, removing part of the batter and adding cocoa powder. That’s it!

Marble Banana Bread

How to Make Marbled Banana Bread

In a mixing bowl combine the melted butter and brown sugar and mix together until combined. Add the bananas and mash them up with the mixture until there are no large lumps. Add the buttermilk and vanilla continue mixing until everything is combined.

Now, add the dry ingredients and mix just until combined. Do not overmix.

Remove about 1 cup (you don’t have to measure it perfectly) and add 1/4 cup cocoa powder. Stir until combined.

Use a cookie or ice cream scoop to take turns scooping in the regular batter with the chocolate batter into the prepared pan. Then use a knife to drag the batter back and forth 3 or 4 times to create the marbling effect.

Once the bread cools, you can slice it and impress everyone who will think you labored over this beautiful bread.

Happy Baking!

Cooking time






  • Unsalted Butter, melted 113g
    (1/2 cup)

  • Light Brown Sugar 120g
    (2/3 cup)

  • Large Eggs 2

  • Bananas 500g
    (about 4 medium bananas)

  • Buttermilk 60g
    (1/4 cup)

  • Vanilla 2 tsp

  • All Purpose Flour 300g
    (2 cups)

  • Baking Soda 1 tsp

  • Baking Powder 1 tsp

  • Salt 1/2 tsp

  • Cocoa Powder 25g
    (1/4 cup)


  • Preheat the oven to 350°F. Spray or butter a 9×5 loaf pan.
  • Beat together the melted butter and brown sugar for 3 minutes.
  • Add the eggs, one at a time, beating for one minute after the addition of each egg.
  • Add the bananas and vanilla and beat for 3 more minutes. If you are mixing by hand, smash the bananas with a fork or potato masher before adding to the butter/sugar/egg mixture.
  • Add the dry ingredients and mix just until combined.
  • Separate about 1 cup of batter and add the cocoa powder and stir until combined.
  • Alternate adding scoops of the regular batter and a little bit of the chocolate batter to the prepared pan. When all batter has been added, use a knife to swirl the batter 3 or 4 times to give it a marbled effect.
  • Bake for 50-60 minutes, or until a cake tester inserted in the middle comes out mostly clean. It may have some moistness from the bananas but there should be no wet bread on the tester.
