I made really pretty cupcakes for a bake sale and the buttercream crusted. I don't use buttercream often so I was wondering is it ok to have crusted frosting on a cupcake?

It's fine

Mine always does it, unless I'm being lazy and using store-bought.

Completely fine! I guess I'm a little curious why you were wondering if it is OK or not.....

Powdered sugar b/c? Yeah, normal.

I hope they sell out for you!!

What do you normally use? And what do you mean when you say "crusted"? I always use a crusting buttercream - usually so its easier to smooth the icing out... but even with a cupcake where you may not need to smooth - I don't see where the problem would be. It's still frosting....

Thats what I always use. No problems for me.

I LOVE the crusted part of icing!

I specifically use a recipe that crusts so I can smooth it with my Viva.

Unless you specifically use a formula that results in a non-crusting bc, then yeah - its supposed to crust.

Thanks for all the replies. Actually they we're has hard as I thought they were.
Once at room temp they were crusty to the touch and soft and fluffy inside. I'll post a pic when I get some.
Thanks again.
