Thanks to the onset of root beer flavored ales, there are several ways of making an easy root beer float cocktail. You can simply add a scoop of vanilla ice cream to any root beer flavored beer. Not complicated but not all that interesting either.
Another option? Back in the seventies we used to drop a jigger of root beer schnapps right into a pint of regular beer for an alcoholic root beer treat and all you'd have to do is add a scoop of ice cream to that. Pretty darn sweet, but it works as well.
However, my favorite root beer cocktail is now this version. Thanks to the addition of Art In The Age's Root Liqueur and some bitters it is less sweet and has way more depth of flavor.
ROOT BEER FLOAT
1-1/2 Oz. Vodka
1 Oz. Root Beer Schnapps or Liqueur
1 Scoop Vanilla Ice Cream
2 Dashes Chocolate Bitters
Shake the vodka and root beer liqueur with ice until chilled.
Add the scoop of ice cream to your chilled glass.
Strain the chilled vodka and root beer vodka over the ice cream.
Tap the bitters on top of the ice cream, add a spoon and straw then serve.
TO MAKE A
Simply add some actual root beer just after adding the ice cream.
