Step 1: Prep the Cake Mix
Prepare the chocolate cake mix according to package instructions. Pour the batter into a greased 9×13 baking pan.
Step 2: Make the Cream Cheese Mixture
In a separate bowl, beat together the softened cream cheese, butter, powdered sugar, and vanilla until smooth and creamy.
Step 3: Assemble the Earthquake Cake
Spoon dollops of the cream cheese mixture over the cake batter. Sprinkle chopped Reese’s, chocolate chips, and peanut butter chips evenly across the top. Gently swirl everything with a butter knife to create that “earthquake” effect.
Step 4: Bake to Gooey Perfection
Bake at 350°F (175°C) for 35–40 minutes, until the edges are set but the center is still a little gooey (that’s the magic!).
Step 5: Cool Slightly & Serve
Let the cake cool for about 15 minutes before serving. Drizzle with melted peanut butter or chocolate syrup if desired.
Tips for the Best Earthquake Cake
- Don’t overbake: A slightly gooey center is what makes it irresistible.
- Switch it up: Try Reese’s Pieces or peanut butter chips for even more texture.
- Serve warm: A scoop of vanilla ice cream on top takes it to the next level.
- Make ahead: Store covered at room temperature for up to 3 days, or refrigerate for a denser texture.
