Crust: Cream butter and sugar until light and fluffy. Stir in vanilla. Gradually beat in flour and mix well. Pat dough evenly over bottom of ungreased jelly roll pan. Bake at 350 for 20 minutes until Lightly browned. Cool.
Cream Cheese Topping: Beat cream cheese until smooth. Add eggs and vanilla and beat until smooth. Stir in sugar. Fold in sour cream. Spread over cooled crust. Bake at 350 for 30-35 minutes. Cool before cutting. (I think it's easier to cut them when still warm.)
