Whip the Cream

Make the Cake Batter Filling

1. In a large bowl, beat the softened cream cheese and butter together until smooth and lump-free.

Fold and Assemble

1. Gently fold the whipped heavy cream into the cream cheese mixture using a rubber spatula until combined.

3. Spread the filling evenly into the premade graham cracker pie crust and smooth the top with a spatula.
