Can someone help me figure out how to get an off white or antique white fondant? I'm going to use regular vanilla, but I don't think that will get it to the shade I'd like.

Ivory food colour gel added very carefully. Americolor brand excellent shade.

wow...I've never heard of it. Thanks!

I use a full pound of butter in my buttercream, and with three tablespoons of vanilla it's very off-white.

Yes, what she said
And/or what Annie Cahill said

Just use Fondarific antique white fondant
