In a mixing bowl, beat the softened cream cheese and powdered sugar together until smooth and creamy, scraping down the sides to fully incorporate the sugar.

In a separate bowl, combine the yellow cake mix and water. Stir gently until just combined, leaving some lumps to avoid overmixing.

Pour the cake batter evenly into the prepared baking dish. Spoon dollops of the cream cheese mixture over the batter and use a spatula to swirl it gently, creating a marbled effect.
