Sonic Drive-In is catering to the season with a limited time only Pumpkin Pie Shake. The indulgent frozen dessert drink is a hand-mixed shake made of real ice cream, real pumpkin, nutmeg, cinnamon, pie crust pieces and a whipped topping (with even more pie crust pieces for good measure).

A regular 14 oz. shake will set you back 710 calories, 34 grams of fat and credit you with 9 grams of protein. If you opt for the larger 20 oz. serving, you'll be sipping back 1040 calories, 47 grams of fat and 13 grams of protein.
