If you have glass mugs or decorate hurricane glasses for serving the butterbeer in, stick them in the freezer to become frosty.
Beat the heavy cream, powdered sugar, and vanilla until soft peaks form. Set this aside in the fridge to chill until ready to use.
Make sure the cream soda is well chilled before starting. Pour about 1 cup into a large pitcher or punch bowl. Whisk in the butterscotch topping and butter extract. Gradually stir in the remaining cream soda until combined.
Fill the individual frosty glasses or mugs with the whipped cream and drizzle with additional butterscotch topping. Ten points for Gryffindor if you have gold star sprinkles to sprinkle on top.
