Chocolate Marbled Banana Bread

Chocolate Marbled Banana Bread

This jam-packed loaf of chocolate chip marbled banana bread is calling your name. I hope you have some ripe bananas ready because you might just want to make it right away. P.S. I’m totally eating a slice right now while I write this post and OMG… it’s so good.

Banana Bread Batter

You just need to whip up two separate batters using flour, cocoa, sugar, baking powder, baking soda, salt, bananas, butter, eggs, sour cream and vanilla.

And then just mix a bunch of chocolate chip morsels into each batter.

Swirled Banana Bread Batter

Layer small spoonfuls of both batters in a 9 X 5 inch loaf pan and then gently make a couple of swirls in the batter with a knife. Don’t over mix it though.

  6. Love this recipe! Do you also have it converted into grams? Would love to try it.

  7. This loaf was very moist, and it looked beautiful with the swirls of chocolate and regular batter! My daughter and husband, who love bananas, thought it was fantastic. My son and I, who aren’t crazy about bananas, thought the banana flavor was overpowering. But if you like bananas, this is a great loaf of banana bread!

  8. Hey girl, I was just thinking about the time I made chocolate bread for my family, and in the same moment I was scrolling through your site looking for perhaps cake pops or brownies, and lo and behold, I saw this recipe. It was too long ago I made banana bread, its delicious, and this recipe has BOTH. What am I doing on Sunday?

  9. I made this once before but don’t think I got to add a post to tell you how much I loved it. My coworkers loved it, as well! It’s not difficult at all. I love everything about it. Especially how moist it turns out! Thanks for the recipe! It’s a fave but definitely need to make it more often. But it’s in the oven, right now! It will be great in the morning with raspberries and my coffee!

  11. This bread is in the oven and I can’t wait for it to come out! I did notice the batter was super thick but I didn’t find it effected anything. The fams on the way home so I can’t wait to take it out do the oven. 

  12. What would you need to do to use the small loaf pans?

  13. My batter was not very wet, so I added more sour cream and it ended up turning out really well! But why was the batter so dry?
