Great this time of the year, I found this recipe in the local paper in 2004. When my sister visited recently, we made this cake to use up some pumpkin I had on hand. If you use canned pumpkin it is really simple and delicious. Although it was called a Pumpkin Bar in the original recipe, it's more of a cake in texture. The recipe makes enough for a traditional jelly roll pan (15" x 10" x 1") and is not sufficient for a full half sheet (typically 18' x 13" x 1"). You could cut it into bars, or serve it in squares more like cake. It works fine to make as a dessert for a crowd, when several dessert options may be available.
