I had some leftover pumpkin from when I made pumpkin bread and wasn't really sure what to do with it. I raided my cupboards and this is what I came up with. I thought it was pretty darn tasty, and it stayed moist. As far as icing or topping the cake, I used leftover streusel I had in the freezer, but feel free to use your imagination. I think it'd be great with a cream cheese frosting.
