What you’ll need

For the cake:

• All-purpose flour
• Granulated sugar – there is less sugar than usual to make up for the sweet frosting that goes on top.
• Baking powder and baking soda create the light, fluffy texture of this cake.
• Pure vanilla extract and ground cinnamon
• Oil adds moisture and creates a delicate crumb.
• Greek yogurt or sour cream – adds richness and a bit of tang.
• Lemon juice adds the acid needed to create a chemical reaction with the baking soda.
• Ripe bananas – this is the perfect way to use up those over-ripe bananas you have sitting on the counter.
• Egg – adds richness and color to the cake.
• Chocolate chips – who doesn’t love a pop of chocolate when they bite into their cake?

For the frosting:

• Smooth peanut butter – homemade or store-bought.
• Unsalted butter
• Powdered sugar
• Unsweetened cocoa powder – I used Hershey’s
• Vanilla
• Milk – you can use regular or dairy-free in this recipe.
• Sea Salt Flakes – adds a bit of saltiness to balance out the sweetness.

How to make Chocolate Chip Banana Cake with Peanut Butter Frosting

Preheat oven to 350° F. Spray a 8 x 8 x 2 baking pan with baking spray, set aside.

Banana Chocolate Chip Cake

Whisk the dry ingredients together in a large bowl. Set aside.

In a medium bowl, whisk together the Greek yogurt, vanilla, lemon juice, egg, and oil until well combined.

Next, mix in the mashed banana and stir to combine.

Pour the liquid ingredients into the dry ingredients and mix just until well combined.

Stir in the chocolate chips.

Pour into the prepared baking dish and smooth the top to even it out.

Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Allow cake to cool completely before frosting.

Peanut Butter Chocolate Frosting

Beat peanut butter and butter together until light and smooth.

Add half of the milk (3 tablespoons) and vanilla and beat to combine.

Mix in the powdered sugar and cocoa powder.

Gradually add the remaining milk until you reach your desired consistency.

Spread frosting over the completely cooled cake.

Sprinkle with sea salt flakes, if desired, slice and serve.
