Ingredients

Scale

Chocolate Cake

1 box chocolate cake mix
Ingredients required for cake mix (usually eggs, oil, and water as per package instructions)

Peanut Butter Mixture

1 jar (16 oz) creamy peanut butter
2 cups powdered sugar

Reese’s Toppings

1 cup crushed Reese’s peanut butter cups
1 cup mini Reese’s peanut butter cups, chopped

Whipped Topping

1 tub (8 oz) whipped topping (like Cool Whip)

Chocolate Ganache Drizzle

1 cup semi-sweet chocolate chips
2 tablespoons butter
1/4 cup heavy cream

Instructions

Preheat Oven: Preheat your oven to the temperature specified on the chocolate cake mix box to ensure even baking.
Prepare Cake Batter: Follow the instructions on the chocolate cake box by mixing the cake mix with the required eggs, oil, and water until smooth. Pour the batter into a greased baking dish evenly.
Make Peanut Butter Mixture: In a separate bowl, combine the creamy peanut butter and powdered sugar, mixing well until the mixture is smooth and spreadable.
Add Peanut Butter Dollops: Drop spoonfuls of the peanut butter mixture on top of the cake batter in the baking dish, distributing them evenly to create pockets of rich flavor.
Top with Reese’s Cups: Sprinkle the crushed Reese’s peanut butter cups and chopped mini peanut butter cups over the cake batter and peanut butter dollops for added texture and taste.
Bake the Cake: Place the baking dish in the oven and bake according to the time and temperature instructions on the cake mix box until a toothpick inserted near the center comes out clean.
Cool and Add Whipped Topping: Remove the cake from the oven and allow it to cool slightly. Then, gently spread the whipped topping over the surface of the cake for a light, creamy layer.
Prepare Chocolate Ganache: In a microwave-safe bowl or small saucepan, melt together the semi-sweet chocolate chips, butter, and heavy cream, stirring until smooth and glossy.
Drizzle Ganache: Drizzle the warm chocolate ganache evenly over the whipped topping layer for a beautiful, shiny finish and extra chocolate flavor.
Set Before Serving: Allow the cake to sit at room temperature or refrigerate briefly so the ganache sets before slicing and serving.

Notes

Use a glass or metal baking dish around 9×13 inches for even baking and best layering.
You can substitute mini peanut butter cups for chopped regular Reese’s cups if mini are unavailable.
For easier spreading, let the peanut butter mixture soften slightly at room temperature before mixing with powdered sugar.
If you prefer a stronger peanut butter flavor, add an extra 1/2 cup of creamy peanut butter to the mixture.
This cake can be refrigerated for up to 3 days and tastes great slightly chilled.
To make clean slices, chill the cake before cutting and use a sharp knife wiped clean after each slice.
