In a small mixing bowl, mix together the whipped cream, butterscotch topping, melted butter, butter extract, and caramel extract.
Add 2 tablespoons each, of the whipped cream mixture, into the bottom of 2 mugs.
Then pour 1 cup of the cream soda into each mug and stir.
Add 2 more tablespoons of the whipped cream on top of each mug and stir.
The mixture will fizz up and the whipped cream will expand, creating a fizzy top that'll give you a butterbeer mustache when you drink it.
