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. Beat until completely smooth and well incorporated.
03 - Spread cake batter evenly in the prepared pan. Sprinkle chopped strawberries, coconut, and white chocolate chips uniformly over the batter.
04 - Beat cream cheese and butter together in a separate bowl until smooth. Gradually add powdered sugar, continuing to beat until creamy and fully blended.
05 - Drop large spoonfuls of cream cheese mixture randomly across the top of the cake.
06 - Gently swirl a knife through the cream cheese and batter to marble. Avoid overmixing to maintain distinct layers.
07 - Bake for 45 minutes until edges are set and center remains slightly wobbly.
08 - Allow cake to cool for at least 30 minutes before serving. Enjoy warm or at room temperature.
