Chocolate Guinness Boozy Milkshakes

0 Blend the ice cream and Guinness together in a blender.
1 Combine the half-and-half with the sugar and Irish whiskey in a medium-sized bowl, and whip for five minutes using a hand mixer. (The mixture will get fluffier, but it won't turn into whipped cream.)
2 Pour a little bit of the milkshake into a cup, then add a little Irish Whiskey Cream, and continue this process back-and-forth until two milkshakes have been made.
3 Enjoy cold!
