If you make cupcakes and have them sitting out for a few hours, how do you keep them soft and moist? I have found that when I make them, but have to wait until the event which could be a few hours away, makes the cake and frosting harden. How do I keep this from happening?
Your cake shouldn't harden within a few hours, so you may need to look at other recipes. As for the frosting, you could try a meringue buttercream as it doesn't crust over like a traditional buttercream.
If you are using American Buttercream it is supposed to form a hard crust on the outside. Have you actually tried the cupcakes to see if the cake is hard? The ABC should keep them nice and moist. If not then you need to find a new recipe.
didn't you say yesterday that your cupcakes were not cooking properly, some were uncooked, now they're dry. maybe someone you know who bakes well could tutor you a bit. just to get you kick started.
