Reese’s Peanut Butter Earthquake Cake

A Dessert That Shakes the Soul and Melts the Heart

Introduction

Imagine a dessert that blends the decadence of chocolate cake with the creamy richness of peanut butter and cream cheese. Now add melty pockets of chocolate chips and the nostalgic joy of Reese’s flavors—and you have the Peanut Butter Earthquake Cake. This cake doesn’t just sit pretty—it erupts with flavor in every gooey, messy, magnificent bite. A favorite among peanut butter lovers and chocolate enthusiasts alike, this cake has become a potluck legend and family favorite.

History & Formation

The “earthquake cake” concept originated in the American South, a land rich in dessert traditions. The name comes from the way the cake “cracks” and shifts while baking, creating swirls and crevices that resemble an earthquake’s aftermath. Bakers started playing with the recipe, and soon, the Reese’s Peanut Butter twist was born—an irresistible combination that took this treat to a whole new level.

Ingredients

For the Cake Base:

  • 1 box chocolate fudge cake mix
  • Ingredients listed on the cake mix box (typically eggs, oil, and water)

For the Cream Cheese Layer:

  • 8 oz cream cheese, softened
  • 1/2 cup peanut butter (creamy or crunchy)
  • 1/2 cup unsalted butter, melted
  • 1/2 tsp vanilla extract
  • 4 cups powdered sugar

Add-ins & Toppings:

  • 1/2 cup semi-sweet chocolate chips
  • Optional: chopped Reese’s peanut butter cups, chopped peanuts, peanut butter drizzle

Instructions

Step 1: Preheat & Prep

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper.

Step 2: Prepare the Chocolate Cake

Mix the cake mix according to package instructions (usually includes eggs, oil, and water). Pour the batter into the prepared baking dish.

Step 3: Make the Earthquake Layer

In a separate bowl, beat the softened cream cheese, melted butter, and peanut butter until smooth. Add vanilla extract. Gradually mix in the powdered sugar until fully incorporated and thick.

Step 4: Layer the Chaos

Drop spoonfuls of the peanut butter mixture on top of the chocolate cake batter. Don’t spread it—just drop it randomly. As it bakes, it will sink, swirl, and create that signature “earthquake” look.

Step 5: Add the Magic

Sprinkle semi-sweet chocolate chips and optional chopped Reese’s cups over the top.

Step 6: Bake

Bake for 40–45 minutes, or until the edges are set and the center is slightly jiggly but not liquid. The cake will have cracks and swirls—this is what you want.

Step 7: Cool & Serve

Let the cake cool in the pan for at least 30 minutes before cutting. Serve warm for gooey delight or chilled for a firmer bite.

Serving Suggestions

  • Serve with a scoop of vanilla ice cream
  • Drizzle with extra melted peanut butter or chocolate syrup
  • Enjoy with coffee, milk, or cold brew
