I am going to make a batch of this tonight for a cake for easter. I avoid fondant becuase of the taste of most but I need more practice so I figured a cake for the family dinner is the way to go.

Can I make this in my kitchen aid?

I do. But I prefer Michele Foster's Fondant (white chocolate version) HANDS DOWN!!! for taste and workability and I make it in my mixer as well. Easy peasy.

If I am making marshmallow fondant --this is the recipe I use. I do make it in my KA. After it gets to its final stages I knead it on a silicone mat for a minute or two then wrap it and store it in a freezer bag on the counter. It can be used immediately; however, it works best if you let it sit up to a minimum of four hours.

My favorite fondant overall is Michele Foster's as well; however, instead of making the white chocolate version anymore, I knead white chocolate candy clay into it and it makes the most incredible tasting/working fondant I have ever used!
