Double Chocolate Chip Banana Bread

While I absolutely love a classic banana bread, it’s also fun to make different variations as well. This double chocolate banana bread is a favorite, as well as chocolate chip banana bread, cranberry banana bread and pumpkin banana bread.

Banana bread is a staple at our house and is one of our favorite quick bread recipes. We absolutely love my classic chocolate chip banana bread, however adding the extra cocoa powder makes it feel extra special. My kids always get so excited when the bananas are over ripe, so we can start baking.

The cocoa in the batter and chocolate chunks studded throughout add the perfect flavor. This recipe is so easy to make and has the perfect balance of bananas. It is very moist and rich in flavor. It could almost pass off as chocolate cake, but then we wouldn’t be able to eat it for breakfast…and I’m all about eating banana bread for breakfast. ;)

Recipe Ingredients

  • Chocolate: The rich chocolate flavor comes from both the unsweetened cocoa powder and chocolate chips. A chocolate lover’s dream with double the chocolate!
  • Sour cream: This is the secret ingredient in this recipe. Don’t worry, you can’t taste it but it makes the consistency extra soft and tender.
  • Butter: I like to use salted butter for the extra flavor. Make sure it’s at room temperature before using. Check out how to soften butter quickly.
  • Bananas: Using ripe bananas with brown spots will give you a sweeter taste with a moist texture. Mash them well with a fork before using.
  • Sugar: Although the bananas add some sweetness, this chocolate banana bread recipe also calls for granulated sugar to give it the perfect sweet flavor.
  • Eggs: Help give the bread structure, as well as a tender texture.
  • Vanilla: Give it an extra boost of flavor by using high quality pure vanilla extract.
  • Flour: All-purpose flour is used as the base of the dry ingredients. Make sure you know how to measure flour accurately so that your bread isn’t too dense, dry or heavy.


  • Feel free to use Greek yogurt in place of sour cream.
  • Chocolate chunks also work great, as well as milk chocolate chips.
  • Add in 1/2 cup chopped nuts (pecans or walnuts) for an extra crunch.
  • Drizzle melted peanut butter over the top, or use half semi-sweet chips and half peanut butter chips for more peanut butter flavor.

How to Make Chocolate Banana Bread

Step by step collage making chocolate banana bread.
  1. Wet ingredients. In a large bowl, cream together the softened butter and sugar until smooth. Next add the eggs, mixing them in one at a time. Then add the vanilla and sour cream.
  2. Dry ingredients. In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda and salt. Slowly add the wet mixture to dry mixture and stir until combined. Then fold in the bananas and chocolate chips.
  3. Pour into pans. Pour into 2 greased large loaf pans and top with a few extra chocolate chips if desired.
  4. Bake. Place in the oven and bake at 325°F for about 50 to 60 minutes. Make sure bread comes clean with toothpick. Remove from oven and let cool for at least 10 minutes before removing the bread from the pan. Then transfer to a wire rack to cool completely.

Expert Tips

  • Line your pan with parchment paper for easy removal.
  • Use ripe (brown spotted) bananas for optimal sweetness.
  • Don’t over beat the batter. Just mix until combined so the bread stays moist and fluffy.
  • Test with a toothpick before removing from oven. It should be clean. If not, bake for a few more minutes then test again.

Recipe FAQs

What’s the best way to store chocolate banana bread?

I recommend storing the bread in an airtight container or bag at room temperature. It will stay fresh for up to 5 days. Storing it in the refrigerator may cause the bread to dry out.

Can it be frozen?

Yes! Wrap the loaf tightly in plastic wrap or foil, then place in a freezer bag and freeze for up to 6 months.

Can I make one loaf instead of two?

Sure! Simply cut the recipe in half, pour into a single loaf pan and bake as directed.

Can this recipe be made gluten-free?

Although I haven’t tried, you could swap all-purpose flour for a 1-to-1 gluten-free flour for those who have a gluten allergy or sensitivity.
