If you are looking for a fun and festive boozy eggnog cocktail then you have found the one you are going to make this year. While I call this Grinch Spiked eggnog, because I made it for a fun movie night for myself, this spiked eggnog recipe is one that is simple to make. With some store-bought eggnog, rum, and a little bit of sparkle this is one of my favorite holiday cocktails to make.
