We enjoyed making this Reese’s Peanut Butter Earthquake Cake. So simple to whip up using a chocolate cake mix and other ingredients. The cake doesn’t slice neatly and is more like a spoon cake, which is totally perfect. This is chocolate heaven!

The Ingredients

Here’s what you’ll need to make Reese’s Peanut Butter Earthquake Cake (the exact measurements and full recipe instructions are below in the easy to print recipe card):

  • Chocolate cake mix – use your favorite cake mix, such as dark chocolate or devil’s food. You’ll also need the ingredients needed to prepare the cake, such as eggs, oil, and water.
  • Butter – we used regular salted butter, but unsalted will work too.
  • Cream cheese – use full-fat cream cheese.
  • Peanut butter – be sure to use creamy peanut butter for this recipe.
  • Vanilla extract
  • Powdered sugar
  • Semi-sweet chocolate chips – semi-sweet is the right chocolate for this recipe as milk chocolate will burn during the baking time.
  • Mini Reese’s Peanut Butter Cups – find these in the candy aisle of your grocery store.
