Banana Chocolate Chip Cake with Peanut Butter Cream Cheese Frosting

Banana Chocolate Chip Cake is an incredibly moist sheet cake with tons of banana flavor on the inside and a delicious Peanut Butter Cream Cheese Frosting on the outside. Loaded with mashed bananas, buttermilk and mini chocolate chips the secret to this simple recipe is cooling it in the freezer.

No holiday on the calendar has reinvented itself more than Valentine’s Day. From its pagan beginnings as a fertility festival (complete with animal sacrifice and bed partners being randomly drawn like Powerball numbers) to the Roman emperor who chose Cupid’s special day to behead not one, but two men named Valentine, February 14th didn’t exactly exude romance its early years.

Fast forward a few centuries and the sordid traditions of love lotteries and executions were replaced with poetry and paper cards. No one knows exactly why the world went from one extreme to the other, but I have a hunch. Never mind that it’s based on alternate facts and questionable research the reason, my friends, is cake. That’s right, Shakespearean-era people didn’t fall in love with love, they fell in love with a frosted dessert. It’s obvious because I too have found myself more likely rhyme words and doodle hearts after eating cake.

My love for cake runs deep and true. It’s the type of love that should be shouted from the rooftop. Only the roof over my head is moldy and slippery (thank you Florida humidity) so if I crawled atop my house to proclaim that my heart belongs to cake I’d fall and bust my butt. In the interest of personal safety, I’ll shout it from the pages of this blog instead: I, Heather Wolf, am hopelessly devoted to Banana Chocolate Chip Cake with Peanut Butter Cream Cheese Frosting. That’s a mouthful, but oh what a delicious mouthful it is! Packed with mashed bananas and mini chocolate chips you’ll swoon over the combination of incredibly moist cake and peanut butter frosting like you’ve been hit by a chubby cherub’s arrow.

Before sharing the recipe for Banana Chocolate Chip Cake, here are a few baking tips to help you out:

Cake Ingredient Tips

How many bananas do you need for a banana cake? Three large bananas is perfect for this recipe. Be sure to use overripe bananas that are so brown and covered with bruises that they look like Mike Tyson punched them.

Always use the spoon and level method to measure flour. Scooping from the bag overpacks flour into the measuring cup which steals moisture from the cake.

If you don’t have buttermilk, you can make a sour milk substitution by stirring 1 1/2 teaspoons of fresh lemon juice into 1 1/2 cups of whole milk and letting it set for 5 minutes before adding to batter.

Toss mini chocolate chips with a tablespoon of flour before adding to batter to prevent them from sinking while baking.

Cake Preparation Tips

Cool cake in the freezer (yes, in the freezer!) for 45 minutes immediately after removing from the oven. Once cake has cooled completely, top with peanut butter cream cheese frosting.

Banana cake can be made 2 days in advance. Cover the cooled, unfrosted cake in plastic wrap then store in the refrigerator until ready to frost and serve.

How to Store Banana Chocolate Chip Cake

Cover and store frosted cake in the refrigerator up to 5 days.

Can you freeze Banana Cake? Yes, banana cake can be frozen up to 3 months frosted or unfrosted. For best results, double wrap cake, first in plastic wrap then in aluminum foil, before placing in an airtight container in the freezer.
