Leave cream cheese out to soften. Beat until smooth with sugar and vanilla.
Add eggs, one at a time, beating on high. Fold in sour cream.
Will make more than what a 9-inch graham cracker crust will hold.
Bake at 350° F for 30 to 35 minutes, or until crust is golden brown and toothpick comes out clean.
Servings: 2 dozen cupcakes
