01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish thoroughly with butter or cooking spray.
02 - Combine the strawberry cake mix, eggs, vegetable oil, and water in a large mixing bowl. Beat with an electric mixer on medium speed for 2 minutes until smooth and well blended. Pour the batter into the prepared baking dish, spreading evenly.
03 - In a separate bowl, beat the softened cream cheese and butter together until creamy and smooth. Gradually add the powdered sugar and vanilla extract, continuing to beat until the mixture is fluffy and no lumps remain.
04 - Drop spoonfuls of the cream cheese mixture randomly over the surface of the cake batter. Use a butter knife or skewer to gently swirl the cream cheese through the batter, creating a marbled earthquake effect. Avoid over-swirling to maintain distinct pockets of creamy filling.
05 - Scatter the diced strawberries, white chocolate chips, and sweetened shredded coconut evenly across the top of the swirled batter.
06 - Bake for 40 to 45 minutes. The cake is done when the edges are set and slightly golden, while the center retains a gentle gooey texture. A toothpick inserted near the edge should come out clean.
07 - Allow the cake to cool in the baking dish for at least 30 minutes. The center will continue to set as it cools. Serve warm for the most indulgent experience, or let cool completely to room temperature for easier slicing.
