In large mixing bowl, blend cake mix, butter and 1 egg. Pat mixture into buttered 15x10 inch jelly roll pan. Beat cream cheese until fluffy; blend in 2 eggs and sugar. Pour over cake mixture. Spoon Blueberry preserves over top. Sprinkle with coconut and nuts. I only used nuts & it was good.
Bake at 325 degrees for 50 minutes until lightly browned. Cool; cut into bars.
