A deliciously frozen slice of pumpkin pie in a glass.. Just a quick note: You're probably wondering why I'm using ice, when there's ice cream as ingredient... the ice cream tends to want to become creamy after it has been blended with the pumpkin, and the ice just helps to make it more slushy... more icy. If you think you'd prefer the drink creamy, then by all means, leave the ice out, it's not going to make a difference to the taste at all!
