With a few eggs, a dash of nutmeg, and some milk, heavy cream, sugar, and bourbon you can make eggnog, a delicious holiday drink. It’s a common Christmas treat, so it’s no surprise that December is National Eggnog Month. So, if you’re a big fan of eggnog, consider enjoying a batch with homemade gingerbread cookies. Is this drink not your favorite? Try an eggnog-flavored treat instead. There’s eggnog-flavored coffee creamer, eggnog-flavored ice cream, and eggnog cookies. National Eggnog Month is a time to get inventive.
