What do you use to "paint" on fondant?? I want to paint leapord spots on a fondant cake, but what can I use that's edible? HELP please, I have 4 days to figure this out! Thanks

You can dilute some gel food colors in vodka or clear vanilla and use that to paint on fondant. Just be sure not to use too much and dilute the color too far, especially if you're looking for darker colors. The fondant may seem a little sticky right after you first paint it, but the liquid will evaporate in time and the stickiness will disappear.

Will it stay wet? I am just affraid of smudging.

I would test it out on a piece of fondant and see if, after a drying period, how it holds up to smudging. Maybe you could stencil it with butter cream or royal icing.....can you come up with a leopard stencil? i would also test this technique out before hand and compare the 2. Thats how I learn before I actually do it on the final cake.

You can also use dusts and airbrush colors.

I thought about dusts. Can I use petal dust? Do I mix it with water or vodka? I'm going to have to try some test runs before the actual cake.

I suggest you mix it with vodka. Make sure you don't put too much liquid.
