Shelf life on buttercream & cupcakes: Butter cream can be stored in the piping bag, airtight container or freezer bag in the fridge, as long as the expiration date was on the butter.
How can you see if buttercream & cupcakes are good or bad? If it smells or taste bad.
Proper storage of buttercream & cupcakes: Butter cream must either be used immediately,refrigerated or frozen. Cake with buttercream, require refrigeration and should be taken out in room temperature before serving. Defrost time depends on cake-size.
If your buttercream have been refrigerated in a bag or container, take it out 1-1.5 hour before you need it.
Nice-to-know: Buttercream may occasionally separate slightly after thawing, but can be whipped up again at medium speed (in most cases). Chocolate buttercreams can be added melted chocolate (50 – 100 g) and that gets butter cream to regroup.
Can I make buttercream & cupcakes in advance and serve it later? YES! You can freeze butter cream in the piping bag, on the finished cupcake or in an airtight container. I would recommend NOT to freeze cupcake bottom down (cake sponges can be frozen if they are to be assembled with filling), as it may do a little harm in taste and texture. But it can be done without health consequences, so it is a matter of taste.
If you want to finish the cake/cupcake in advance, and put them in the refrigerator until serving, the sponges can be made 2 days before(if they are stored at room temperature), 3 days before(if they are refrigerated). The buttercream can be piped on the cake before the butter in the buttercream expires. Remember, to take the cake/cupcake out in time for serving, so the buttercream is soft and delicious.
