Preheat your oven to 350°F and grease a 9x13-inch baking dish.
In a large bowl, combine the strawberry cake mix, eggs, oil, and water as directed on the box, then pour the batter into the prepared baking dish.
Melt the butter and, in a medium bowl, use an electric mixer to blend the melted butter with the cream cheese until smooth. Mix in the powdered sugar.
Drop spoonfuls of the cream cheese mixture onto the cake batter in the pan.
Break up one white chocolate bar and sprinkle it over the cake batter.
Add 1 cup of chopped strawberries to the cake batter and swirl everything together.
Bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely, then top with the whipped topping.
Use a potato peeler to create white chocolate curls from the remaining bar and sprinkle them, along with the remaining 1 cup of chopped strawberries, over the top of the cake.
Serve and enjoy!
