Place in pre-heated 375 degree oven and bake for 35 minutes. Keep a watch during last 5 minutes that the top of cheesecake does not crack. Carefully remove from oven and set undisturbed to cool to room temperature, then chill in refridgerator for 5-6 hours or overnight before serving. Remove spring form when ready to serve. If desired, before serving, cover with fruit pie filling of choice or serve pie filling on the side.
This can also be made sugar free but substituting the sugar with granulated sugar substitute. As the butter or margarine tends to seep out the bottom of the pan while baking, cover the bottom of the pan with aluminum foil or place on large round pan while baking.
