Hi Sandy! Might want to use a spring form pan, put a layer of the cake in the bottom of the pan than fill it with softened icecream. Put it back into the freezer till that icecream gets really firm. Than take it out to ice it. If your doing alot of decorating it may be alot of in and out of the freezer. I don’t really recommend ganache or buttercream cause they will get pretty hard when frozen. I normally use a sweetened whipped cream like pastry pride your you can make a homemade version. Hope that helps!
