Preheat the oven to 350° and spray a 9×13-inch baking dish with cooking spray.
To a medium bowl, add cake mix, eggs, water, and oil. Mix until combined. Pour the batter into the prepared baking dish.
In a large bowl, use a hand mixer to combine the cream cheese, butter, confectioners' sugar, vanilla, and salt.
Fold in the strawberries.
Dollop the cream cheese mixture over the cake batter. Using a knife, swirl it into the batter.
Sprinkle white chocolate chips on top. Bake for about 50-55 minutes, or until the center is set.
Garnish with diced strawberries. Serve warm with vanilla ice cream.
