In a medium saucepan, mix the cream soda and butterscotch sauce over medium heat. Stir gently until the sauce is fully incorporated.

Continue to heat until the mixture is warm but not boiling.

In a separate bowl, whip the heavy cream until soft peaks form.

Gently fold the vanilla extract into the whipped cream.

Carefully pour the warm butterscotch mixture into your mugs, filling each mug about three-quarters full.

Spoon the whipped cream on top of each mug.

Drizzle extra butterscotch sauce over the whipped cream.

Enjoy your Butterbeer warm while it’s still frothy.
