Decadent Reese’s Cup Chocolate Cake: A Peanut Butter Dream

The aroma of chocolate and peanut butter baking in the oven always takes me back to my childhood. My grandmother, a woman whose love language was baking, would often surprise us with this cake on special occasions. The rich, moist chocolate cake, studded with chunks of Reese’s Peanut Butter Cups, was always a hit, and the decadent frosting was the perfect final touch. It wasn’t just a dessert; it was a symbol of love, warmth, and shared moments. Now, I’m excited to share that same joy with you through this amazing recipe.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 30 minutes
Total Time: 50 minutes
Servings: 15-20
Yield: 1 2-layer cake
Dietary Type: Not Gluten-Free

Ingredients

1 (18 ounce) box chocolate cake mix (I used Devil’s Food)
1/2 cup vegetable oil
3 eggs
1 cup buttermilk
2 cups chopped Reese’s Peanut Butter Cups

For the Frosting:

1 cup heavy cream
8 ounces dark chocolate (I used dark chocolate kisses)
1/2 cup peanut butter

Optional Garnish:

Chopped Reese’s Peanut Butter Cups

Equipment Needed

Two 9-inch cake pans
Mixing bowls
Electric mixer
Whisk
Measuring cups and spoons
Rubber spatula
Saucepan
Cooling rack

Instructions

Preheat your oven to 350 degrees F (175 degrees C). Grease and flour two 9-inch cake pans. This step is crucial to prevent the cake from sticking. You can also use baking spray with flour for an even easier release.
In a large mixing bowl, combine the chocolate cake mix, vegetable oil, eggs, and buttermilk. Use an electric mixer to beat the ingredients together until well combined. Start on low speed to prevent the dry ingredients from flying everywhere, then increase to medium speed.
Gently fold in the chopped Reese’s Peanut Butter Cups into the batter. Distribute the candies evenly throughout the batter to ensure every bite is a delight.
Pour the batter evenly into the prepared 9-inch cake pans. Ensure that both pans have the same amount of batter to achieve even baking and consistent layers.
Bake for 30 minutes at 350 degrees F (175 degrees C). To check for doneness, insert a toothpick into the center of one of the cakes. If the toothpick comes out clean or with a few moist crumbs, the cakes are ready. Be careful not to overbake, as this can result in a dry cake.
Let the cakes cool in the pans for about 10 minutes before inverting them onto a cooling rack to cool completely. Cooling the cakes completely is essential before frosting to prevent the frosting from melting.
While the cakes are cooling, prepare the frosting. In a saucepan, heat the heavy cream over medium heat until it just begins to boil. Watch carefully to prevent it from scorching.
Remove the saucepan from the heat and pour the hot heavy cream over the dark chocolate in a heat-proof bowl. Let it sit for about a minute to soften the chocolate.
Whisk the dark chocolate and heavy cream together until the chocolate is completely melted and the mixture is smooth and glossy.
Stir in the peanut butter and whisk until fully incorporated and the frosting is smooth and creamy.
Once the cakes are completely cool, place one layer on a serving plate or cake stand. Spread a generous amount of the frosting over the first layer.
Carefully place the second cake layer on top of the frosted layer. Pour the remaining frosting over the top of the cake, allowing it to drip down the sides.
(Optional) Sprinkle additional chopped Reese’s Peanut Butter Cups over the top of the frosted cake for added decoration and peanut butter flavor.

Expert Tips & Tricks

For an even richer chocolate flavor, add a tablespoon of instant espresso powder to the cake batter.
If you want a thicker frosting, chill it in the refrigerator for about 30 minutes before frosting the cake.
To prevent the cake layers from sliding, place small strips of parchment paper under the edges of the bottom layer before frosting. This will keep the serving plate clean.
For a smoother frosting, use a high-quality dark chocolate with a higher cocoa percentage.
If you are short on time, you can use store-bought frosting, but homemade frosting elevates the cake to another level.
