01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan thoroughly.
02 - In a medium bowl, toss sliced strawberries with granulated sugar until evenly coated. Set aside to macerate.
03 - Combine strawberry cake mix, melted butter, eggs, and milk in a large bowl. Beat until smooth and well 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 - Beat cream cheese and softened butter in a separate bowl until smooth and creamy. Add powdered sugar and vanilla extract, mixing until fluffy and fully combined.
06 - Drop spoonfuls of cream cheese mixture randomly over the cake batter. Use a butter knife to gently swirl through the batter, creating a marbled pattern. Avoid overmixing to maintain distinct swirls.
07 - Bake for 38-42 minutes until edges are set but center remains slightly gooey. The characteristic earthquake appearance comes from the cracked, uneven top.
08 - Let cake cool in pan for 15-20 minutes before slicing. Serve warm or at room temperature for best texture and flavor.
