Create a tasty alternative to the standard pumpkin pie by creating a pumpkin roll cake. To make this simple tasty treat, prepare a yellow cake mix, according to package directions, adding half a can of prepared pumpkin to the mix to give it a seasonally appropriate flavor. Spread your batter on a jelly roll tray lined with parchment. Cook the cake, watching it closely to ensure that the thin cake layer does not become over done. Let the cake cool after baking. Spread whipped cream or white frosting across the top of your cake layer, then roll up your pumpkin creation to finish your dessert preparation. Peel away the parchment as you roll the cake.
