Generally, you can prepare most Valentine’s desserts 3 days in advance. Some things, like pie crusts, are possible to make weeks in advance and freeze. With so many diverse possibilities, it’s best to err on the side of caution and give your loved one something as fresh as possible! I think it is best to prepare by making sure you have enough of each ingredient, designating bakeware and unique plating possibilities, and making toppings if needed to take away an extra step at the end of baking. That way the desserts are easier to assemble, prepare, and present on Valentine’s Day.
