Ingredients
6 oz chilled root beer
3 small scoops vanilla ice cream (about ¾ cup)
Chilled club soda, seltzer or sparkling water (optional)
Directions
Fill a tall, 14-oz glass ⅓ full with root beer. Add 1 scoop ice cream. Pour about ¼ cup more root beer. Add 2 more scoops of ice cream. Pour in enough root beer to fill glass. Top with club soda, if you like, to add extra carbonation.
