I am making my daughter a lalaloopsy cake and decided to do the houses out of gingerbread. I want to cover them in royal icing and all the fondant piece designs (door, crayons, etc.) then insert the house into the cake. I'm worried the gingerbread and royal icing will get soft inside the cake and buttercream icing though. Does anyone know if this would work or have another idea? Her party is May 4 so i'm running out of time.
