I am making my daughter's birthday cake and I would like the top layer to be a chocolate cake with chocolate frosting. I am covering in fondant and was wondering if I had to dirty ice with BC or if I could just use store bought chocolate icing for under the fondant to make it stick.

ive ues it before (check out my pictures its the snowflake one) and it worked great. Ran out of icing sugar one say and used it.

The store bought will work just fine. The fondant just needs anything to moisten the cake to adhere to it. I would treat it like you would BC, make the cake as perfect as possible and do a thin layer of the icing.

Thank you so much for the replies! This is going to be my first two tiered cake ever and I have been keeping myself up at night with questions in my head!
