01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan thoroughly.
02 - In a medium bowl, toss sliced strawberries with granulated sugar. Set aside to macerate while preparing remaining components.
03 - In a large bowl, combine strawberry cake mix, melted butter, eggs, and milk. Beat until smooth and fully incorporated. Spread batter evenly into prepared pan.
04 - Scatter sugared strawberries, white chocolate chips, and shredded coconut evenly over the surface of the cake batter.
05 - In a separate bowl, beat cream cheese and softened butter until smooth and creamy. Add powdered sugar and vanilla extract, mixing until fluffy and well combined.
06 - Drop spoonfuls of cream cheese mixture randomly over the batter and toppings. Use a butter knife to gently swirl, creating a marbled pattern. Do not overmix—the distinct layers create the earthquake appearance.
07 - Bake for 38 to 42 minutes until edges are set but center remains slightly gooey. The cracked, marbled top is characteristic of this dessert.
08 - Cool in pan for 15 to 20 minutes before slicing. Serve warm or at room temperature.
