This Chocolate Chip Banana Cake with Peanut Butter Frosting is bursting with banana flavor, wonderfully moist, and finished with a smooth peanut butter frosting. The classic trio of banana, peanut butter, and chocolate is irresistible.
I adore the combination of peanut butter and chocolate. When a few overripe bananas appeared on my counter, it felt like the perfect reason to bake this favorite flavor pairing.
You really don’t need an excuse to make something delicious, but this cake is a great one.
Presenting the Chocolate Chip Banana Cake with Peanut Butter Frosting.
This is a moist banana cake rich with banana flavor and dotted with mini chocolate chips. It’s finished with creamy peanut butter frosting and sprinkled with mini chocolate chips, chopped peanut butter cups, and a chocolate drizzle for an extra touch of decadence.
The bananas naturally sweeten the cake and add a mellow, comforting flavor that pairs beautifully with salty peanut butter and sweet chocolate. Although the toppings are indulgent, the cake itself remains balanced and not overly sweet.
What makes this cake especially wonderful is its moist, tender crumb. A few key elements contribute to that texture:
- A mix of brown sugar and white sugar for depth and moisture
- Ripe bananas that add natural sweetness and moisture
- Buttermilk to create a soft, tender crumb
- Sour cream to prevent any dryness and keep the cake rich
Because this recipe is baked in a 9×13-inch pan, it’s much simpler than assembling a layered cake but still looks impressive. The full recipe and helpful tips are available from the original author on Oh Sweet Basil—see the source for precise measurements and step-by-step instructions.
