Classic banana bread is a good thing. And, apparently, I just can’t seem to leave a good thing alone!

I’ve added a cozy fall twist with my Apple Banana Bread, summer freshness with my Strawberry Banana Bread, and then there’s my irresistible tropical-inspired Jamaican Banana Bread.

This chocolate-peanut butter version evolved from a chocolate banana bread recipe I used to make way back in time. That bread was very good, but after a suggestion made by my husband, it got even better. “You know, this would be really good with peanut butter in it”.

After I got over the shock of him making a suggestion for modifying a recipe, I tried it and he was right. This Chocolate Peanut Butter Banana Bread is absolutely delicious.

What’s not to love? The chocolate peanut butter combination is solid.

How to Make Chocolate Peanut Butter Banana Bread

Before beginning, preheat your oven to 350 degrees F. and coat a 9- x 5-inch loaf pan with nonstick cooking spray.

Make the Batter

  1. Using an electric mixer in a large bowl, mix the butter and sugar until light and fluffy. Add the eggs and peanut butter and beat again until creamy and well combined. Then, beat in the mashed bananas and vanilla until smooth.
  2. In a separate medium mixing bowl, whisk together the flour, baking soda and cocoa powder. Add half the dry mixture to the wet mixture and mix with a wooden spoon until just combined.
  3. Add half the sour cream and mix again. Repeat with the remaining dry mixture and sour cream.
  4. Mix in the chocolate chips.

Bake

  1. Transfer the batter to the greased loaf pan and bake in the preheated oven for 55 to 60 minutes, or until a toothpick inserted into the center of a loaf comes out clean.
  2. Remove from the oven and allow to cool in the loaf pan on a wire rack for 20 to 30 minutes (or until cool enough to handle) before turning out on the wire rack to cool completely.

Storage Tips

Chocolate Peanut Butter Banana Bread can be wrapped in foil or stored in an airtight container at room temperature for up to 4 days. Be sure the loaf has completely cooled to avoid condensation and place a paper towel underneath the bread to absorb any excess moisture. To extend its life, transfer it to the refrigerator and it will stay fresh for over a week.

For longer storage, banana bread freezes well. First, wrap either the entire loaf or individual slices in a layer of plastic wrap to prevent freezer burn. Then, transfer the bread to a freezer-safe plastic storage bag, label it with the date, and freeze it for up to 3 months.

Notes

For Mini Muffins
Fill greased mini muffin cups about ¾ full with batter. Bake at 350 degrees F for 15 minutes or until a toothpick inserted into the center of a muffin comes out clean. Yields approximately 36 mini muffins.
Storage
Wrap the completely cooled loaf in foil or transfer to an airtight container and store at room temperature for up to 4 days. Be sure the loaf has completely cooled to avoid condensation and place a paper towel underneath the bread to absorb any excess moisture. To extend its life, transfer it to the refrigerator and it will stay fresh for over a week.

Questions & Reviews

  1. Christine says:

    Due to my only moderately stocked kitchen — I had to make some changes to this recipe but it still turned out beautifully. I was out of coco, so I melted 1/2 a cup of semi sweet chocolate chips, and incorporated them with the peanut butter once cooled. (This meant that I also cut back on my white sugar). I used 1 cup brown sugar, 2/3 cup white sugar. I was also out of sour cream, so I used 3% fat greek yogurt.
    I am sure the result was different than your great recipe here, but it turned out great!
    Thank you for the great basic recipe!

    1. Valerie says:

      Great things can come out of changes like this! I’m happy it worked out well for you with what you had on hand 🙂

  2. Wendy says:

    Excellent! Hubby said fantastic!

  3. Wendy says:

    My husband asked for banana peanut butter chocolate muffins this morning and your recipe came up on my Internet search. I had lots of substitutes like Greek yogurt for sour cream, baking squares for cocoa and some of the butter, oats for some of the flour, and I added pecans for the chocolate chips. Just went with what I had on hand (kept running out of ingredients because I doubled the recipe)! Timer is going off, so time to try them out!

  4. Nami | Just One Cookbook says:

    I definitely need more variation for my banana bread. I have 3 brown bananas too. Sour cream is not our regular item that I use and I don’t have it…. I wonder if I can replace it with yogurt. I am tempted to make this tonight. 🙂

    1. Valerie says:

      I think yogurt would work great, Nami. If you try it, let me know how it turns out.

  5. Kim says:

    I used the your recipe for muffins tonight and everyone loved them! I didn’t have any sour cream and use greek yogurt in its place. They are delicious and so moist!

    1. Valerie says:

      Greek yogurt is an excellent substitution for the light sour cream. So glad your family enjoyed them Kim!

  6. Lynna says:
