01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan thoroughly with butter or cooking spray.
02 - In a medium bowl, combine sliced fresh strawberries with granulated sugar. Toss gently to coat and set aside to macerate.
03 - In a large bowl, whisk together strawberry cake mix, melted butter, eggs, and milk until smooth and fully combined. Spread batter evenly into prepared pan.
04 - Distribute sugared strawberries, white chocolate chips, and shredded coconut evenly over the surface of the cake batter.
05 - Using an electric mixer, beat cream cheese and softened butter until creamy and smooth. Gradually add powdered sugar and vanilla extract, mixing until fluffy and well incorporated.
06 - Drop spoonfuls of cream cheese mixture randomly over the batter. Using a butter knife, gently swirl through the batter to create a marbled pattern, being careful not to overmix.
07 - Bake for 38-42 minutes until edges are set but center remains slightly gooey. The characteristic cracked, earthquake-like appearance should be visible on top.
08 - Allow cake to cool in pan for 15-20 minutes before slicing. Serve warm or at room temperature for optimal texture.
