You can make or prepare most of these New Year's Eve dessert recipes ahead of time. You can store cakes and cookies at room temperature for at least 1-2 days (cookies can be stored even longer). You can also store them in the refrigerator for up to one week or in the freezer for up to 3 months. Confirm full make ahead and storing instructions by checking each recipe.

To reheat any of these desserts and serve them warm as if they just came out of the oven, you can warm them up in a 300F preheated oven for about 5-15 minutes. I would check on it every 5 minutes until warmed through. If heating from frozen, let it thaw first and then reheat.
