I am wondering how are the little figures on this cute cake are made? Whats the material and where can you buy molds and casts to shape them? and how are they so shiny?
These figures are probably made with fondant.
I think the figures are handshaped. There are plenty of tutorials. You can even look for tutorials working with modelling clay. Basically you only need a rolling pin, a knife and tweezers. Cans, forks, any food-safe utensil that has an interesting pattern are useful. Of course there are special molds for fondant but I don't think that you need them unless you want to make fancy things like laces. You can buy molds online but also in some larger hardware stores, supermarktes, or gift shops. It depends on where you are located.
Fondant is quite matt. To make fondant shiny you can
- hold the fondant over steam or
- apply shortening,
- egg whites,
- corn syrup, or
- alcohol on the surface
Ching Chong's answer is already very good. But note that everybody he said can also apply to marzipan figurines, not only fondant ones. This may increase your options, since I think marzipan is somewhat easier to shape.
