1 15 oz can pumpkin (Not pumpkin pie filling!)
1 box Spice Cake mix
1/2 tsp pumpkin pie spice (but don’t sweat if you don’t have it)
3 eggs

Mix it all up like you would a box cake and bake according to the directions on the box! (Although, at the recommendation of our lovely BethKevin, I bake all my cakes at 325.) It’s done when a toothpick comes out clean.
