Don't know what to do with leftover eggnog? You could always make my Eggnog Cookies. Or you could bust out the bread and make yourself some eggnog French toast. Two yummy solutions.
We used challah, but you can use whatever bread you've got. Soak the slices in eggnog that you've accented with whatever complementary flavors you have on hand. For example, add a splash of vanilla extract, a few teaspoons of cinnamon or nutmeg, or maybe even a dash of ginger or pumpkin pie spice.
Fry the soaked bread slices in butter until the bread warms all the way through and is brown and toasty--about 2-3 minutes on each side. Top with maple syrup and a big, honkin' dollop of butter. (Paul Deen...paging Paula Deen!) It's the holidays on a plate.
