Will buttercream icing make gingerbread house soggy?
I'm trying a bit of a combination cake for my son's birthday but can't find it done anywhere before so hoping it's not a ridiculously bad idea!
Plan is to make a house "core" from normal spongecake, cover with buttercream icing and stick gingerbread walls and roof on top of that... So basically it looks like a gingerbread house but has cake inside!
I'll still use royal frosting to build the house but on the inside it'll be stuck to buttercream. Has anyone done this and did it work? Or will the buttercream make the gingerbread too soggy to stand?
