Earthquake Cake is a rich, easy chocolate cake loaded with pecans, coconut, chocolate chips, and a gooey cream cheese filling that cracks through the top as it bakes. The name comes from the way the cake shifts, splits, and erupts in the oven, creating a messy, beautiful dessert that tastes even better than it looks.
This recipe starts with a chocolate cake mix, which keeps everything simple. Then pecans and coconut go into the bottom of the pan, cake batter goes over them, and a sweet cream cheese mixture gets spooned on top in big dollops. As the cake bakes, the cream cheese sinks, bubbles, and bursts through the chocolate layer like built-in frosting.
I first had Earthquake Cake at a family gathering where the dessert table had plenty of pretty options, but this messy chocolate cake disappeared first. It looked cracked and wild, yet everyone kept going back for “just one more small piece.” The cream cheese tasted like cheesecake, the chocolate stayed soft and rich, and the coconut-pecan layer added the perfect chewy crunch. Since then, this cake has become one of those dependable recipes I make when I want a dessert that feels fun, easy, and completely irresistible.

Notes
Why Earthquake Cake Is So Easy to Love
It Uses a Cake Mix
Earthquake Cake starts with boxed chocolate cake mix, so you do not need to measure flour, cocoa, baking powder, or sugar. Just prepare the batter according to the package directions and pour it over the pecans and coconut.
Because the base stays simple, the cream cheese filling becomes the star. It adds richness and gives the cake its signature cracked look.
It Frosts Itself
This cake does not need frosting. The cream cheese, butter, and powdered sugar mixture works like a built-in frosting that bakes into the cake.
As it heats, it moves through the batter and creates gooey pockets. That means every slice has chocolate cake, cheesecake-like filling, and sweet topping all in one.
Ingredients for Earthquake Cake
Cake and Bottom Layer
For Earthquake Cake, you need chopped pecans, sweetened flaked coconut, chocolate cake mix, and the eggs, oil, and water listed on the cake mix box.
You can use cooled black coffee instead of water for deeper chocolate flavor. You can also omit the nuts or coconut if preferred.
Cream Cheese Filling and Chocolate Chips
The filling uses melted salted butter, room-temperature cream cheese, and powdered sugar. Make sure the cream cheese is soft so it blends smoothly.
Chocolate chips are optional, but they add extra chocolate flavor and make the top look even better. Semi-sweet chips balance the sweet filling nicely.
How to Make Earthquake Cake
Prepare the Pan and Filling
Preheat the oven to 350 degrees Fahrenheit. Spray a 13×9-inch, 3-quart baking pan with cooking spray.
Scatter pecans and coconut evenly across the bottom. Then beat melted butter and cream cheese until smooth. Add powdered sugar one cup at a time and mix until creamy.
Assemble and Bake
Prepare the chocolate cake batter according to the box directions. Pour it over the pecans and coconut.
Next, spoon big dollops of the cream cheese mixture over the cake batter. Use about 8 heaping tablespoons so the filling has enough weight to break through the cake.
Sprinkle chocolate chips over the top and bake immediately for 40 to 45 minutes, or until the cake is set.
Tips for the Best Earthquake Cake
Use Big Cream Cheese Dollops
Small spoonfuls can disappear into the cake. Big dollops create the dramatic cracks and gooey pockets that make Earthquake Cake special.
Also, get the cake into the oven right after assembling it. This helps create the best earthquake effect.
Customize the Add-Ins
The classic combination uses pecans and coconut, but you have room to adjust. Use fewer pecans, less coconut, or more chocolate chips if you like.
German chocolate cake mix also works well. For a different twist, try dark chocolate cake mix or add a handful of chopped walnuts instead of pecans.
