Combine 1 cup plus 2 tablespoons cream cheese, 1/4 cup unsalted butter, and a "scant" 1/2 cup whole milk in a double boiler (or, make your own by placing a heatproof bowl over a saucepan containing 2-inches of water, ensuring that the bottom of the bowl does not touch the water). Cook over medium heat, whisking occasionally, until the cream cheese and butter is completely melted and the mixture is completely pale yellow.
