Pour 1.5 ounces of butterscotch schnapps over the top of the ice cream in each mug.
3 ounces butterscotch schnapps
Tilt glass and slowly pour root beer down the side; this helps to control the amount of foam. One 12 ounce can will be enough to split between two cocktails.
12 ounces root beer
Top with whipped cream, a cherry, and add a straw. You may need to scoop some extra foam off the top first.

Notes
Chill the Glass: Place your mug or glass in the freezer for 15-20 minutes beforehand. A frosty mug keeps the ice cream from melting too quickly.
We actually use zero sugar root beer for this! Regular root beer, craft root beer, or even cream soda will work too.
One 12-ounce can of root beer makes 2 perfect root beer float cocktails.
