I was just wondering if MMF Fondant ever fully hardens?
Like enough to use as a free standing topper on a cake?If so, how long does it take?
Or if not, what should I use to make it stiff (or maybe use only gumpaste - will that be strong enough)?

I kneaded in some powder gumpaste and it had gotten stiffer before I rolled it out, but 24 hours later I am wondering if it will harden enough to stand straight up? It is rolled about 1/8" thick.

Thanks so much!

It does, but from my experience it does take a while. I have some MMF bears, candycanes and other decorations I made for fun a couple of years ago and they are completely hard. They are either made from all MMF or MMF with gum-tex added to it.

Gumpaste would harden completely for you overnight.

It should harden up if you've added some gum-tex or tylose to your fondant. It might help though that when you mold first mold it that you insert a skewer (or something similar) and use that to help you anchor it into the cake.

Thanks,

I will give it a try!

You could also try mixing your fondant 50/50 with gumpaste. I just recently started doing that and it works out really well.
