Divide the caramel into its three jobs
The three tablespoons are split between two glass drizzles and the blender mixture. Measure that division before starting so the shake does not receive the entire amount as well as a second unmeasured drizzle. Use plain pumpkin puree, with the cinnamon measured separately, to keep the written flavor balance.
Prepare the glasses before blending. A brief blend should combine the ice cream, milk and pumpkin while retaining thickness; stop and scrape only as the machine instructions allow. Divide into the large glasses, leaving space for the measured cream topping. Serve at once, keeping spare ingredient containers stored properly instead of leaving the ice cream out while the finished drinks are decorated.
