I bought unsalted butter by mistake, can I still use it to make butter creme frosting? Will that change the taste? Do I add salt?

I actually use the unsalted butter all the time with my bc. It will be fine. I never add salt to mine and I have never had a complaint one. If you decide that you would like to add salt to it, most get a finer salt such as regular popcorn salt. A little goes a long way. Good luck to you
sincerely

I agree, I use only unsalted and I never have any problems!

I *think* the screen name says easy 4 you 2 see 98 but not sure what it means!
