01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan thoroughly.
02 - Combine strawberry cake mix, eggs, oil, and water in a large bowl. Mix until completely smooth and well incorporated.
03 - Pour cake batter evenly into the prepared baking pan, spreading to corners.
04 - Sprinkle chopped strawberries, shredded coconut, and white chocolate chips evenly over the surface of the batter.
05 - Beat cream cheese and butter together in a separate bowl until smooth. Gradually add powdered sugar, beating until creamy and fully combined.
06 - Drop large spoonfuls of cream cheese mixture randomly across the top of the cake.
07 - Using a knife, gently swirl cream cheese mixture into cake batter to create marbled appearance. Avoid overmixing to maintain distinct layers.
08 - Bake for 45 minutes until edges are set and center is slightly wobbly.
09 - Cool for at least 30 minutes before serving. Serve warm or at room temperature.
