Preheat oven to 350. In a large bowl, combine, sugar, flour, cream cheese and egg until smooth. Open the tube of biscuits and separate into 10. Arrange in a 8 or 9 inch round cake pan. Press firmly over bottom and up the sides of the pan to form crust. Patch as necessary. Pour cream cheese mixture over crust. Bake at 350 for 24-30 minutes or until crust is a deep golden brown. Cool 20 minutes and serve warm or refrigerate until cold. Promptly refrigerate leftovers.
*I never use processed foods in my baking (except for this recipe) and no one has ever guessed that this is what the crust is made of.
