I am making a giant cupcake for the first time for my daughter's bday. I've noticed that most people cover the bottom of the cupcake with chocolate candy melts to look like a cupcake liner. I was wondering if I could just cover it in fondant instead? Thanks for your help in advance.

Not really specific to your answer, but I made a giant cupcake for a friend ( its in my gallery), and I covered the top in fondant and the bottom part of the cupcake in Swiss meringue buttercream. I am sure you could use fondant. It held up really well. I drove it about 20 miles to my friends house. Of course I used dowels just as I would have with a stacked wedding cake. Hope this helps.

I've made quite a few of them and use melted chocolate but you can use fondant too.

How about using kit cat bars? You can separate the sticks and put them around the sides maybe with a little buttercream and a ribbon to look nice? Haven't tried it but it would be an interesting look.
