Peanut Butter Earthquake Cake

šŸ«šŸ„œ A Chocolate-Peanut Butter Lover’s Dream!


šŸ“œ Introduction

The Ā Peanut Butter Earthquake Cake is not just a dessert—it’s a gooey, indulgent, flavor-exploding experience. Loaded with rich chocolate, creamy peanut butter, and tangy cream cheese, this cake is named for the way it bakes: the dense filling bubbles up and cracks through the chocolate cake like a delicious earthquake. If you’re a fan of Reese’s Peanut Butter Cups, this cake is your dessert destiny!

Whether for birthdays, bake sales, holidays, or ā€œjust because,ā€ this show-stopping cake satisfies even the fiercest sweet tooth. It’s easy to make using a boxed cake mix, yet fancy enough to impress guests.


šŸ›’ Ingredients

For the Base:

  • 1 box chocolate cake mix (plus ingredients listed on the box—usually eggs, oil, water)

For the Creamy Swirl:

  • ½ cup (1 stick) unsalted butter, melted
  • 8 oz (1 block) cream cheese, softened
  • ½ cup creamy peanut butter
  • ½ tsp vanilla extract
  • 4 cups powdered sugar

For the Mix-Ins:

  • ½ cup semi-sweet chocolate chips
  • ½ cup peanut butter chips (optional but highly recommended)
  • ½ cup chopped Reese’s Peanut Butter Cups (about 4 regular cups)

šŸ‘©ā€šŸ³ Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
  2. Prepare the cake mix according to the instructions on the box. Pour the batter into the prepared baking dish and spread it evenly.
  3. In a large bowl, beat together the cream cheese and melted butter until smooth and creamy.
  4. Add the peanut butter and vanilla extract and continue mixing.
  5. Gradually mix in the powdered sugar, one cup at a time, until thick and smooth.
  6. Drop spoonfuls of the cream cheese mixture over the cake batter. Do not spread—this is what creates the ā€œearthquakeā€ effect.
  7. Sprinkle the top with chocolate chips, peanut butter chips, and chopped Reese’s cups.
  8. Bake for 40–45 minutes, or until the edges are set but the center is still a little gooey.
  9. Let cool slightly before cutting. Serve warm for the best molten, gooey texture.

šŸ•°ļø History of the Earthquake Cake

The original Earthquake Cake likely dates back to American kitchens in the 1970s, a time when boxed cake mixes were booming and creative home bakers experimented with gooey fillings and mix-ins. This Reese’s version adds a peanut-buttery twist to the classic, inspired by the unbeatable chocolate + peanut butter combination that Reese’s popularized since 1928.
