You’ll need:

Chocolate cake mix (or homemade chocolate cake batter)
Eggs
Oil or melted butter
Water or milk
Cream cheese, softened
Creamy peanut butter
Powdered sugar
Vanilla extract
Reese’s peanut butter cups, chopped
Chocolate chips

Reese’s are essential here.
They melt into the cake as it bakes, creating pockets of chocolate-peanut butter goodness that define this dessert.

Cream cheese and peanut butter swirl through the center, giving the cake its signature “earthquake” texture.

🍰 How to Make Reese’s Chocolate Peanut Butter Earthquake Cake

Start with the chocolate base.
Prepare the chocolate cake batter according to package or recipe instructions. Pour it into a greased baking dish, spreading it evenly.

Make the peanut butter swirl.
In a bowl, beat together cream cheese, peanut butter, powdered sugar, and vanilla until smooth and creamy. This mixture creates the gooey, cracked center that makes earthquake cake so irresistible.

Layer the indulgence.
Drop spoonfuls of the peanut butter mixture over the cake batter. Sprinkle chopped Reese’s and chocolate chips generously across the top.

Let it bake imperfectly.
Bake until the edges are set but the center is still soft and slightly jiggly. Cracks will form naturally as the cake bakes — that’s exactly what you want.

Cool slightly before serving.
This cake is best served warm, when the center is gooey and the Reese’s are melted.
