Ingredients

Scale

Chocolate Cake

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

Peanut Butter Topping

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

Reese’s Peanut Butter Cups

  • 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 (such as Cool Whip)

Chocolate Ganache Drizzle

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

Instructions

  1. Preheat the Oven: Preheat your oven to the temperature specified on the chocolate cake mix box to ensure the cake bakes evenly.
  2. Prepare the Cake Batter: Follow the package instructions to prepare the chocolate cake batter using the required ingredients like eggs, oil, and water. Pour the batter into a greased baking dish evenly.
  3. Mix Peanut Butter Filling: In a separate bowl, thoroughly mix the creamy peanut butter and powdered sugar until you achieve a smooth, spreadable consistency.
  4. Layer Peanut Butter on Batter: Drop spoonfuls of the peanut butter mixture randomly over the prepared chocolate cake batter, allowing some ripples and pockets of peanut butter throughout.
  5. Add Reese’s Peanut Butter Cups: Sprinkle the crushed and chopped Reese’s peanut butter cups generously over the top of the cake batter and peanut butter drops for added texture and flavor.
  6. Bake the Cake: Bake the cake according to the instructions on the cake mix box, typically until a toothpick inserted in the center comes out clean.
  7. Cool and Add Whipped Topping: Once baked, allow the cake to cool slightly so the toppings won’t melt. Then, spread the whipped topping evenly over the entire cake surface for a light and fluffy finish.
  8. Prepare Ganache Drizzle: Melt the semi-sweet chocolate chips, butter, and heavy cream together in a microwave-safe bowl or over a double boiler until smooth and glossy.
  9. Drizzle Ganache: Carefully drizzle the warm chocolate ganache over the whipped topping, creating an attractive finishing touch.
  10. Set and Serve: Let the cake set at room temperature or refrigerate briefly to allow the ganache to firm up before slicing and serving.

Notes

  • Ensure to evenly disperse the peanut butter mixture over the batter for the characteristic ‘earthquake’ effect.
  • Use a greased or parchment-lined baking dish to prevent sticking.
  • For best results, allow the cake to cool enough before adding the whipped topping to avoid melting it.
  • Store leftovers covered in the refrigerator; allow to come to room temperature before serving for optimal texture.
  • This cake pairs wonderfully with a scoop of vanilla ice cream or a glass of cold milk.
