Cut into squares and serve cold. Use a sharp knife for neat slices. Garnish with extra Cool Whip or fresh cherries if desired. Store covered in the fridge for up to 3 to 4 days. Can freeze pieces for up to 1 month, but texture may change after freezing and thawing. Tips include softening cream cheese to room temperature, pressing the crust firmly, and using a silicone spatula to spread layers.
