Put mugs in the freezer about an hour before you need them to get them nice and cold.

Place 10 scoops of ice cream (about half the carton) into a blender. Add 2 cups cream soda and 1/2 cup butterscotch topping. Blend until combined.

Pour into chilled mugs and top with Redd-wip. Drizzle with butterscotch topping and serve with a straw.
