🍫🥜 Reese’s Peanut Butter Earthquake Cake Recipe

Ingredients

For the Cake Base:

  • 1 box chocolate cake mix (plus ingredients listed on the box: eggs, oil, water/milk)
  • 1 cup sweetened shredded coconut (optional but traditional in earthquake cakes)
  • 1 cup semi-sweet chocolate chips
  • 1 cup chopped pecans or walnuts (optional for crunch)
  • 1 cup mini Reese’s Peanut Butter Cups (halved)

For the Cream Cheese Peanut Butter Swirl:

  • 8 oz cream cheese (softened)
  • ½ cup unsalted butter (softened)
  • 2 cups powdered sugar
  • ½ cup creamy peanut butter
  • 1 tsp vanilla extract

For Topping:

  • ½ cup Reese’s Pieces or extra chopped mini Reese’s cups
  • Drizzle of melted peanut butter or chocolate (optional)

Instructions

Step 1: Preheat & Prepare Pan

  1. Preheat oven to 175°C (350°F).
  2. Grease a 9×13-inch baking pan.
  3. Sprinkle the bottom with coconut, chocolate chips, and nuts (this forms the “earthquake” base).

Step 2: Prepare the Chocolate Cake Mix

  1. In a large bowl, prepare the cake batter according to the package directions.
  2. Pour the batter evenly over the coconut, chocolate chips, and nuts in the pan.

Step 3: Make the Cream Cheese Peanut Butter Swirl

  1. In a mixing bowl, beat together cream cheese and butter until smooth and creamy.
  2. Add powdered sugar, peanut butter, and vanilla. Mix until well combined and fluffy.
  3. Drop large spoonfuls of this mixture over the chocolate cake batter.

Step 4: Add Reese’s & Swirl

  1. Scatter halved Reese’s Peanut Butter Cups evenly over the top.
  2. Using a knife or skewer, gently swirl the cream cheese mixture into the cake batter (do not overmix – you want ribbons).

Step 5: Bake

  1. Bake for 40–50 minutes, until the center is set but still slightly gooey (it should jiggle a little – that’s the “earthquake” effect).
  2. Remove from oven and let cool for at least 20 minutes before cutting.

Step 6: Garnish & Serve

  1. Top with Reese’s Pieces or extra chopped peanut butter cups.
  2. Drizzle with melted chocolate or peanut butter for extra indulgence.
  3. Slice into squares and serve warm or at room temperature.

🍽️ Serving Suggestions

  • Best enjoyed slightly warm with a scoop of vanilla ice cream.
  • Store leftovers covered at room temp for 2 days or in the fridge for up to 5 days.
  • Can be reheated in the microwave for a gooey texture.

🔥 Chef’s Tip: If you love extra peanut butter flavor, swirl in 2–3 tbsp of warmed peanut butter directly into the cake batter before baking.
