Decadent Chocolate Peanut Butter Cake

The first time I made a chocolate peanut butter cake, it was a complete accident. I was rushing to prepare a dessert for a potluck and, in my haste, I mistakenly grabbed peanut butter instead of the vanilla extract. The result? A surprisingly harmonious blend of rich chocolate and nutty peanut butter that had everyone begging for the recipe. Now, it’s a deliberately crafted favorite – a testament to happy accidents and the enduring power of flavor combinations!

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 25-30 minutes
• Total Time: 1 hour (plus chilling time)
• Servings: 12-16
• Yields: 1 cake
• Dietary Type: Not Gluten-Free

Ingredients

• 1 (18 ounce) box devil’s food cake mix
• 1 cup water
• 3 eggs
• ⅔ cup vegetable oil

For the Frosting:

• 8 ounces cream cheese, softened
• 6 tablespoons butter, softened
• ⅔ cup peanut butter
• 3 cups powdered sugar

For the Ganache:

• 8 ounces chocolate chips
• 2 tablespoons light corn syrup
• ½ cup half-and-half

Garnish:

• 2 Reese’s Peanut Butter Cups, chopped

Equipment Needed

• Electric mixer
• 3 8-inch cake pans (or 2 9-inch cake pans)
• Parchment paper (optional)
• Cooling rack
• Microwave-safe bowl

Instructions

1. Begin by setting out your cream cheese and butter to allow them to come to room temperature. This will ensure a smooth and creamy frosting.
2. In a large mixing bowl, combine the devil’s food cake mix, water, eggs, and vegetable oil.
3. Using an electric mixer, beat the ingredients together for 2 minutes until well combined. The batter should be smooth and free of lumps.
4. Prepare your cake pans. Grease and flour three 8-inch pans, or two 9-inch pans, depending on your desired number of layers. You can also line the bottoms of the pans with parchment paper for easier removal.
5. Divide the cake batter evenly among the prepared pans.
6. Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the cake is no longer jiggly in the middle.
7. Let the cake layers cool in the pans for 15 minutes before inverting them onto a wire rack to cool completely.
8. While the cake layers are cooling, prepare the frosting. In a large mixing bowl, beat the softened cream cheese, butter, and peanut butter together until light and fluffy.
9. Gradually add the powdered sugar, ½ cup at a time, while continuing to beat the frosting until it’s all incorporated and smooth. Resist the urge to overmix.
10. Once the cake layers are completely cooled, begin assembling the cake. Place one layer on a serving plate or cake stand and spread a generous amount of the peanut butter frosting evenly over the top. Repeat with the remaining layers.
11. After frosting all the layers, place the cake in the refrigerator to chill slightly while you prepare the chocolate ganache coating.
12. In a microwave-safe bowl, combine the chocolate chips and light corn syrup.
13. Microwave for 30 seconds, then stir. Microwave for another 30 seconds until the chocolate chips are melted and smooth. Continue stirring to ensure even melting; avoid overheating.
14. Whisk in the half-and-half until the ganache is smooth and shiny.
15. Remove the cake from the refrigerator and slowly pour the warm ganache over the top, allowing it to drip down the sides.
16. While the ganache is still wet, chop the Reese’s Peanut Butter Cups and sprinkle them on top of the cake.
17. Chill the cake, uncovered, in the refrigerator for at least 30 minutes to allow the ganache to set before serving.

Expert Tips & Tricks

• For an extra moist cake, consider adding a simple syrup after baking. Mix equal parts water and sugar, heat until the sugar dissolves, and brush it over the cooled cake layers before frosting.
• If your ganache is too thick, add a little more half-and-half, a tablespoon at a time, until it reaches the desired consistency.
• To prevent the cake layers from sticking to the pans, use a baking spray that contains flour or dust the pans with cocoa powder instead of flour.
• If you want a more intense peanut butter flavor, add a pinch of salt to the frosting.
