Non-Alcoholic Shakes: Substitute the creme de menthe for 1 teaspoon peppermint extract and skip the vodka. Increase milk to 1/3 cup. Add a few drops of green food coloring to make them green.
Make it Green: Creme de menthe comes in green or white, which is clear. If you have white, you can add a few drops of green food coloring to make the shakes a festive green color.
Vodka: We used whipping cream vodka, vanilla vodka or plain vodka works great too.
Storage: Leftover milkshakes can be frozen in an airtight container up to 1 month.
