or try modeling chocolate instead of fondant. Easier to use. Tastes better too.

You shouldn't have any trouble. The fondant is so much thicker than frosting, I cannot imagine the frosting bleeding through. Just make sure your frosting is of a stiff enough consistency to hold the fondant. That will be the trickiest part--thin enough to flow the way you want but stiff enough to hold the fondant and keeping it at that consistency for the duration of frosting.

PP Thanks for your reply. I don't want to cover the whole cake with fondant, just add a few details. It is a character and I was thinking I could do the eyes and clothing details with fondant and place on top of the regular frosting. Do you think that will work?
Thanks!

Yes, you absolutely can and should frost first but fondant is tricky. You might need to practice on something with shaving cream on it before you ruin your cake. Good luck.

Frost a cake with both frosting and fondant?
I am making my daughter a fancy birthday cake with chocolate frosting, but would like to add some details made out of fondant. Would that work? or will the fondant slid from the frosting or come through it (i.e if the fondant is white will the chocolate background make it look brownish) ? Any tips?
I have never used fondant as I think it tastes horrible, but there is no way I can make what she wants with regular frosting.
Thanks a lot!
