Cream Cheese Layer

8 oz. cream cheese, softened.
1/4 cup sugar
1 egg yolk
1 c. whipped cream or cool whip OR 2 Tbsp milk (to help it spread easier)

Blend well with a mixer and spread carefully over graham cracker crust.  I use the cool whip to make  the cream cheese layer go farther when I'm making a small gluten free pan as well.
