Can't get enough eggnog? Make this Eggnog French Toast! It's a great way to use up leftover eggnog in a festive holiday breakfast. This recipe gets double egg goodness with the egg bread and the eggnog. Challah is a tasty choice but any bread will work well. French toast is a good way to use up day-old bread. I can’t drink too much eggnog all by itself because it’s too rich on its own for my palate. However, I can have endless amounts of things made with eggnog, such as this Eggnog French Toast!
