Chocolate Chip Banana Cake
If you have ripe bananas sitting on your kitchen counter, then this Chocolate Chip Banana Cake is the perfect way to use them. This cake is moist, delicious, and filled with chocolate chips!

Hi! It’s Jodi again from 5 Boys Baker. Today I’m sharing a recipe for Chocolate Chip Banana Cake, which is the perfect thing to make with those aging bananas sitting on your kitchen counter. 😊
I’m funny about bananas. I like them, but I don’t love them. It’s not my fruit of choice. I’d much rather eat an apple, strawberries, raspberries, watermelon, etc. On the rare occasion I eat a banana, it must be firm with the skin still slightly green, there can’t be even one spec of brown on it.
Now, offer me some banana bread, banana cake, a banana Laffey taffy, a banana creamy ice cream bar, and I’m all over it. For some reason, I always seem to have 3 bananas on my counter, turning darker every day so I’m always looking for new recipes to use them in.

This Chocolate Chip Banana Cake has been a huge hit at my house. My husband declared it “absolutely fabulous” and my two oldest sons have told me over and over again how much they love it. They also think the chocolate frosting is a must. You can certainly leave it off or even swap it out for cream cheese frosting.
This wonderful cake is so moist, delicious and filled with chocolate chips! If you have elderly bananas sitting on your counter, you really need to make this cake with them. 😀


Chocolate Chip Banana Cake
Ingredients
Cake:
- 1/2 cup salted butter softened
- 1/2 cup sugar
- 1/2 cup brown sugar
- 2 eggs
- 2 medium ripe bananas, mashed (about 1 cup, a little less is fine)
- 2 teaspoons vanilla
- 1/4 cup sour cream
- 1 ¾ cup flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup mini chocolate chips
Frosting:
- 3 tablespoons salted butter softened
- 1 ¾ cup powdered sugar
- 2 tablespoons cocoa
- 1 teaspoon vanilla
- 3 to 4 tablespoons milk
Instructions
Cake:
- Preheat oven to 350 degrees F. Spray a 9×9-inch pan with cooking spray. In a medium bowl, whisk together flour, baking powder, baking soda and salt, set aside.
- In the bowl of a stand mixer, fitted with the paddle attachment ( or in a medium bowl using a handheld electric mixer), cream together the butter and sugars until light and fluffy, 2-3 minutes, scraping down the sides of the bowl as needed.
- Add the eggs and mix until combined. Add the bananas, vanilla and sour cream and mix well. Add the dry ingredients and mix until just blended. Stir in the chocolate chips.
- Spread batter evenly into the prepared pan and bake 30 to 40 minutes, or until a toothpick inserted in the center comes out clean. Let cake cook completely and frost with chocolate frosting (if desired).
Frosting:
- In a small mixing bowl, place softened butter, cocoa, powdered sugar, vanilla and milk. Mix with an electric hand mixer, beating until smooth. (Add as much milk as needed to get desired consistency).

Looks good! I want to make this. Can I use regular milk in the icing??
I always have that on hand.
Yes you can use regular milk!
Should this be doubled to make in 9×13 pan?
Yes, if you would like to double it then bake in a 9×13-inch pan. 🙂
