Cream cheese frosting question
I'm going to be freezing unfrosted cupcakes and I want to be able to frost just a few at a time.
I'd like to make a cream cheese frosting for them, but I'm wondering how long it can be stored in the fridge when it's not on a cupcake. Any ideas?
If you're just using cream cheese, butter and sugar, it should last a good while. If you check the expiration date on your cream cheese, that's probably a good estimate of how long you can leave it.
I don't know about cream cheese frosting but I do know that a regular buttercream gets dry and grainy after about two weeks. (I've had leftovers that I stored in the fridge and used to sandwich Nilla wafers.) My guess is that store-ability is related to the amount of fat in a frosting, as the more liquid (milk, cream, lemon juice, whatever) is used to thin the frosting to a spreadable consistency evaporates over time. I've seen recipes with proportions of one 3-oz block to 4 c of powdered sugar, to one 8-oz block to 1 c powdered sugar. I'd bet that the former lasts better in the fridge.
You can also freeze your cream cheese frosting. I've done it with great success. I'd suggest freezing in portions small enough to frost just a few cupcakes at a time. Then, defrost the frosting along with the cupcakes, stir well and frost!
