In a large mixing bowl, combine 2 ounces of softened cream cheese, 1 cup of sifted confectioners' sugar, 1/3 cup of half and half, and 1 teaspoon of vanilla extract. Using an electric mixer, beat the ingredients until smooth and creamy.
Once your cream cheese mixture is smooth, add in 1 cup of creamy peanut butter. Mix until fully incorporated and the mixture is fluffy.
In a separate bowl, pour 1 1/2 cups of heavy whipping cream. Using the electric mixer, whip the cream until it forms soft peaks.
Gently fold the whipped cream into the peanut butter mixture using a spatula.
Pour the creamy peanut butter filling into your prepared 9-inch chocolate cookie crust or graham cracker crust. Spread it evenly with the spatula.
Refrigerate your pie for at least 2 hours to allow it to set. Slice and serve chilled for the best experience!
