01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish thoroughly with cooking spray or butter.
02 - Combine strawberry cake mix, eggs, vegetable oil, and water in a large bowl. Beat with electric mixer on medium speed for 2 minutes until smooth and well-blended. Pour batter into prepared baking dish, spreading evenly.
03 - Beat softened cream cheese and butter together in separate bowl until creamy and smooth. Gradually add powdered sugar and vanilla extract, continuing to beat until fluffy and no lumps remain.
04 - Drop spoonfuls of cheesecake mixture randomly over cake batter. Use knife or skewer to gently swirl through both layers, creating marbled pattern without over-mixing.
05 - Scatter diced strawberries, white chocolate chips, and shredded coconut evenly over surface of swirled batter.
06 - Bake for 40 to 45 minutes until edges are set and center appears slightly gooey. The earthquake effect creates cracks and crevices—this is desired texture.
07 - Let cake cool in pan for minimum 30 minutes before slicing. Serve warm or at room temperature for best texture and flavor.
