When it comes to preparing and storing coffee cake at home, you need to keep a few basic rules in mind. According to the food blog Lil Luna, coffee cake remains edible for about a week if you store it in the fridge in an airtight container. On the other hand, if you’re storing the cake in a container on your kitchen counter, it’s best to consume the dessert within two days. But if you really want to make your coffee cake last for a long time, store it in the freezer and you’ll be good to go for as long as three months.
A Redditor has an extra tip for making coffee taste as good as new the next day. “Put it in an airtight container with a slice of plain white bread,” they advised. “Or wrap it in cling film.” A smart idea, eh?
