Begin by adding two scoops of vanilla ice cream to a tall glass.
Pour cola over the top to fill the glass. Be careful not to overfill.
Garnish with a maraschino cherry. Enjoy immediately.
Notes
To make an adult drink, add a shot of dark rum, vanilla vodka or bourbon to the top of the float. Adding a shot (one ounce) of any liquor you love most will turn it into an alcoholic coke float.
Some recipes call for whipped cream with sprinkles and a maraschino cherry on top.
I like to serve my floats with a straw and a spoon. Much like a milkshake, it's fun to have both options.
Try chocolate ice cream instead of vanilla for a slight variation. Even better, make one of each and compare, choosing a favorite.
If you want to go even more old school, use sparkling water and flavored syrups to create your sodas from scratch.
Use cold soda for the best possible drink on a hot summer day. You can also add a chilled glass (just pop it in the freezer for at least 30 minutes before serving).
