This is based on a lemon cheesecake bar recipe a friend of my son's mom made. I've been making it for 28 yrs. and is now a favorite with all his golfing buddies. I make 2 -4 lemon cheesecake bars when they go to tournaments. I made with pumpkin because my grandsons love pumpkin pie but everyone makes traditional pumpkin cheesecake with my family isn't big on, so... I made a smaller pie first time and hubby liked having a choice. Second time I made 2 pans of bars and froze some. When thawed they were just liked fresh baked and not soggy. Hope You Enjoy!!!
