Let’s dive into the details of this heavenly creation.


Gather the following ingredients to create your own Chocolate Peanut Butter Earthquake Cake:

  • 1 Box Dark Chocolate Fudge Cake Mix (plus required oil, eggs, water)
  • 8 oz Softened cream cheese
  • 1/2 Cup softened butter
  • 1/2 Cup Creamy peanut butter
  • 1 teaspoon Vanilla extract
  • 4 Cups Powdered sugar
  • 1/2 Cup Chocolate chips
  • 1 Cup Miniature Reese’s peanut butter cups, unwrapped and cut in halves


Preparing the Base

  1. Preheat your oven to 350°F and generously grease a 9 x 13 baking dish with nonstick cooking spray.
  2. In a large bowl, prepare the chocolate fudge cake mix according to the package instructions, using the specified amounts of oil, eggs, and water. Pour the fudge cake batter into the greased baking dish and set it aside.

Crafting the Peanut Butter Layer

  1. In a separate bowl, combine softened cream cheese, softened butter, creamy peanut butter, and vanilla extract. Mix until the ingredients are well incorporated.
  2. Gradually add powdered sugar, one cup at a time, to the peanut butter mixture. Continue mixing until you’ve added all 4 cups, resulting in a smooth and creamy consistency.

Assembling the Earthquake Cake

  1. Spoon dollops of the peanut butter mixture onto the chocolate cake batter in the baking dish. Gently spread the peanut butter mixture to create a marbled effect.
  2. Sprinkle the halved Reese’s peanut butter cups and chocolate chips evenly over the top of the cake, creating a tantalizing texture.

Baking to Perfection

  1. Bake the cake in the preheated oven for approximately 45-50 minutes. Perform a toothpick test in the center after 45 minutes to check for doneness. The toothpick should come out clean or with a few moist crumbs, but not wet.
  2. Allow the cake to cool slightly before serving. For an extra indulgence, serve warm with a scoop of velvety vanilla ice cream.
