Guinness and ice cream are a match made in heaven in this Guinness milkshake! This boozy milkshake combines good vanilla ice cream, chocolate bitters, a little Irish whiskey, and Guinness.
Add the ice cream to a pint glass or large glass. If it's hard to scoop, let it soften a bit.
Top with 1/2 oz whiskey and 2 dashes of chocolate bitters.
Top with the Guinness (Pour in two steps; for the 1st pour, pour it halfway up the glass at an angle, then let it settle for a minute, then top off the glass).
