Decadently delicious, eggnog crème brûlée makes the perfect ending for your Christmas dinner. It's a luscious dessert of creamy custard with the rich flavor of eggnog hidden under a crunchy layer of brûléed sugar. It may look fancy, but with only five ingredients, it's easier than you would expect. Even better, you can make it in advance and brûlée the tops just prior to serving.
