Pumpkin "unroll" or Pumpkin cake

I LOVE pumpkin roll... it's always been a holiday favorite. Sometimes though, I just don't feel like rolling it! It's a lot of trouble to roll the cake and let it cool, what if you want some while it's still slightly warm? So I made the 'Libby's famous pumpkin roll, but I was rebellious and didn't roll it! AND it was delicious anyway! I love their cream cheese frosting.. more cream cheesy with less powdered sugar than a lot of cream cheese icing recipes. I dare you to make it  and NOT roll ... YUMMO!
