Pooker...thats very similar to the recipe that I use. I get one pumpkin roll out of each recipe.
If you buy the big can of pumpkin puree they say you can get 4-5 pumpkin rolls out of the one can.
I did forget to mention one thing: make sure you use the pumpkin puree and not the pumpkin pie mix. I'm not saying this to be funny, but seriously its happened and it was not pretty
I have both at the shop, because I use the pumpkin pie mix for cheesecakes and cookies and sometimes the cans can look the same in a hurry
Trust me they are not the same
