1 cup creamy peanut butter
1 cup heavy cream

How to Make This Recipe

Preheat the Oven

Prepare the Cake Batter
In a large bowl, combine the chocolate cake mix, eggs, vegetable oil, and water as directed. Mix until the batter is smooth and well combined, with a rich chocolate aroma filling the air.

Make the Peanut Butter Filling
In a separate bowl, beat together the creamy peanut butter, heavy cream, powdered sugar, and vanilla extract until smooth. The mixture should be light and fluffy, evoking a sweet, nutty aroma.
Layer the Cakes
Once the cakes cool, layer them with the peanut butter mixture in between. This filling adds a wonderful creaminess that complements the dense cake.
Frost the Cake
Frost the top and sides of the cake with chocolate frosting, creating a luscious chocolate exterior that beckons to be enjoyed.
Crush and Garnish
Crush the Butterfinger candy bar and sprinkle on top for a crunchy finish that adds texture and sweetness.
Chill Before Serving
Chill the finished cake in the refrigerator for a while before serving. This helps the flavors meld beautifully and makes for easier slicing.
