If you’re overwhelmed with the holidays, take a deep breath and read on. These Eggnog Milkshakes take only 5 minutes to prepare and you really only need 2 ingredients. If you’re having a group of kids or adults over, or just want to make something sweet for your family, these are simple and delicious! For adults, if you want to add bourbon or rum for a nighttime dessert treat, go right ahead. This is my newest favorite Christmas milkshake although everyone still emails me for my recipe for Peppermint Milkshakes from 2008. Find the recipe here.
