The Garden Baker, it’s traditional to cover a fruitcake in marzipan, and then usually the fondant covering is very thin. And Garden Baker is correct, your 2nd tier needs to have it’s own cake board. And you need to put dowels through both tiers, with one central dowel in the middle that should go right through to your main cake board. Since the fruitcake is quite dense, I personally would use sharpened wooden dowels. This will ensure your cake with be sturdy, won’t slide, tip, and be safe to transport.
