01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish thoroughly.
02 - Combine strawberry cake mix, eggs, oil, and water in a large bowl. Beat until well blended and smooth. Spread batter evenly in prepared baking dish.
03 - Beat softened cream cheese and butter until smooth and creamy. Add powdered sugar and vanilla extract; continue beating until fully combined and fluffy.
04 - Drop spoonfuls of cream cheese mixture randomly over the cake batter, leaving some batter visible.
05 - Run a knife or skewer through the batter and cream cheese mixture in swirling motions to create a marbled pattern. Do not overmix.
06 - Sprinkle white chocolate chips, chopped strawberries, coconut, and nuts evenly over the surface of the swirled batter.
07 - Bake for 40-45 minutes until edges are golden brown and center is set. A toothpick inserted should come out with moist crumbs but not wet batter.
08 - Allow cake to cool in pan for at least 30 minutes before serving. Serve warm or at room temperature.
