Marbled Chocolate Banana Bread

This Marbled Chocolate Banana Bread made quite an impression around here – so much so that we saw actual tears when the last few pieces disappeared before we were ready for them to go.  I’m not sure if that tells you how good this bread is, or how much my family loves sweets, but it is what it is!

Don’t you think banana bread in general is a wonderful invention?  Can you imagine the delight that filled the kitchen of the first person who decided to add her yucky black bananas to her bread when she took her (or his) first bite?  Pure genius.

This recipe is fun to make because you take out one cup of the plain batter, and add melted chocolate chips and cocoa powder to make the chocolate marble.  Chocolate and banana are so delicious together, and the texture of this bread with the delicate pieces of sliced almonds is just right!

Sprinkle a few more chocolate chips on top so everyone knows what they are in for, and pop that guy into the oven.  You can also make four mini loaves, just reduce the baking time to about 30-35 minutes.

Ingredients

Scale
  • 1/2 cup butter, softened
  • 1 cup granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1/4 cup sour cream
  • Pulp from 3 ripe bananas, mashed
  • 1 1/2 cup all-purpose flour

  • 1 cup crushed sliced almonds
  • 1/2 cup semi-sweet chocolate chips plus 2 tablespoons, divided

Instructions

  1. Preheat oven to 350 degrees. Line a standard size loaf pan with parchment paper, or spray with nonstick baking spray.
  2. In the bowl of an electric mixer with the paddle attachment, cream butter and sugar together on medium speed. Add eggs one at time and mix. Add vanilla, sour cream, and banana pulp and mix well.

  4. Melt 1/2 cup chocolate chips in a small microwave bowl for 30 seconds. Stir, and microwave for 10 more seconds until completed melted. Be careful not to burn the chocolate.
  5. Place one cup of the banana bread batter into a bowl, and stir in melted chocolate and cocoa powder by hand until it’s completely incorporated.
  6. Add 1/2 cup dollops of the batter to the prepared loaf pan, alternating chocolate and plain. Top with the remaining chocolate chips, and bake for 50-60 minutes, or until the top is dark brown and a toothpick inserted into the center comes out clean.
  7. Use the excess parchment as handles to lift the bread out of the pan, and place it on a cooling rack. Cool completely before cutting. Store in an airtight container.

  1. This is delicious! I made it with half white sugar and half coconut sugar and really liked the taste. The chocolate makes it extra special.

  3. A yummy change-up to traditional banana bread! I will be making this again. Very moist and came out so pretty with the marbling. I used plain greek yogurt instead of sour cream just because I had some to get rid of.
