Okay ladies, for those who asked, and those who are wondering... here's where I got my recipe's for the Buttercream frosting and Marshmallow fondant. I added color to my fondant after I had it made-that was the hardest part. If you are going to just use all one color, I suggest adding the food coloring in the 1st step, before you microwave it.
Good luck! Enjoy! It's sooooooo worth it- There is nothing like a homemade cake!
