01 - Preheat the oven to 350°F. Grease a 9x13-inch baking pan thoroughly.
02 - In a medium bowl, toss the sliced strawberries with granulated sugar. Set aside to macerate while preparing the batter.
03 - In a large bowl, combine strawberry cake mix, melted butter, eggs, and milk. Beat until smooth and fully incorporated. Spread the batter evenly into the prepared pan.
04 - Evenly scatter sugared strawberries, white chocolate chips, and shredded coconut 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 fully combined.
06 - Drop spoonfuls of the cream cheese mixture over the cake batter. Use a butter knife to gently swirl the cream cheese into the batter, creating a marbled effect. Do not overmix—the distinct swirls create the earthquake appearance.
07 - Bake for 38–42 minutes, or until the cake is set around the edges but still slightly gooey in the center. Do not overbake—the characteristic earthquake look comes from the cracked, gooey top.
08 - Cool in the pan for 15–20 minutes before slicing. Serve warm or at room temperature for best texture and flavor.
