Mastering Reeses Peanut Butter Cup Banana Cake with Peanut Butter Cream Cheese Frosting: How-To

Step 1: Prepare the Oven and Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together 2 cups of all-purpose flour, 3/4 teaspoon of baking soda, 1/2 teaspoon of baking powder, and 1/2 teaspoon of salt. Set aside.
Step 3: Cream Butter and Sugar
In a large mixing bowl, using an electric mixer, beat 1/2 cup (1 stick) of unsalted butter and 1 1/2 cups of sugar together until light and fluffy, about 3 minutes.
Step 4: Add the Eggs and Sour Cream
Add 2 eggs, one at a time, mixing well after each addition. Then, mix in 3/4 cup of sour cream until just combined.
Step 5: Incorporate Bananas and Lemon Juice
Add 1 1/3 cups of mashed ripe bananas (about 3 large) and 2 tablespoons of fresh lemon juice to the mixture, stirring until combined.
Step 6: Combine Dry Ingredients with Wet
Gradually add the dry ingredients to the wet mixture, stirring just until combined. Be careful not to overmix.
Step 7: Fold in Reese’s Peanut Butter Cups
Gently fold in 2 cups of unwrapped Reese’s Peanut Butter Cup Minis, reserving 12 for topping the cake.
Step 8: Bake the Cake
Divide the batter evenly between the prepared cake pans and smooth the tops. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Step 9: Cool the Cakes
Allow the cakes to cool in the pans for 10 minutes, then remove them from the pans and transfer to a wire rack to cool completely.
Step 10: Make the Peanut Butter Cream Cheese Frosting
In a large bowl, beat 1 (8-ounce) block of cream cheese and 1/2 cup (1 stick) of unsalted butter together until smooth. Mix in 1/2 cup of peanut butter and gradually add 1 1/2 cups of powdered sugar. Finally, mix in 2 tablespoons of heavy whipping cream until the frosting is smooth and creamy.
Step 11: Frost the Cake
Once the cakes are completely cool, place one layer on a serving plate and spread a generous amount of frosting on top. Place the second layer on top and frost the top and sides of the cake. Decorate with the reserved Reese’s Peanut Butter Cup Minis.
Step 12: Enjoy!
Slice the cake, serve, and watch as everyone dives into this decadent treat!
In-Season Flavor Ideas

Troubleshooting Tips
- If your cake sinks in the middle, it may have been underbaked. Make sure to test with a toothpick and adjust baking time as needed.
- For a denser cake, ensure that you don’t overmix the batter; mix just until combined.
- If the frosting is too thick, add a bit more heavy whipping cream to reach your desired consistency.
