• Prep Time: 15 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour
• Yield: 12 servings

Ingredients

• 1 box chocolate fudge cake mix (plus ingredients listed on the box)
• 1/2 cup creamy peanut butter
• 8 oz cream cheese, softened
• 1/2 cup (1 stick) butter, melted
• 2 cups powdered sugar
• 1/2 cup mini chocolate chips
• 1 cup chopped Reese’s peanut butter cups

Instructions

1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
2. Prepare the chocolate cake mix according to package directions and pour the batter into the prepared pan.
3. In a separate bowl, beat together the cream cheese, melted butter, and powdered sugar until smooth. Gently fold in the peanut butter.
4. Spoon the cream cheese mixture over the cake batter in random dollops — don’t spread it out completely. It will “sink” while baking and create that classic earthquake effect.
5. Sprinkle the top with chopped Reese’s and mini chocolate chips.
6. Bake for 40–45 minutes, or until the edges are set but the center is still slightly gooey.
7. Cool slightly before serving. Best served warm for ultimate gooeyness!

Tips for Best Results

• Use room-temperature cream cheese for a smoother filling.
• Want more peanut butter flavor? Swirl a few extra spoonfuls into the batter before baking.
• This cake is delicious slightly underbaked — that’s the “earthquake” magic!

Storage & Make-Ahead

• Fridge: Store leftovers in an airtight container for up to 5 days. Reheat in the microwave for 15–20 seconds before serving.
• Freezer: Freeze individual slices wrapped in foil for up to 2 months.
