  1. Place the butter in a shallow bowl, and set aside.
  2. Place the marshmallows in a large microwave-safe bowl, and microwave on High for 30 seconds to 1 minute to start melting the marshmallows. Carefully stir the water and vanilla extract into the hot marshmallows, and stir until the mixture is smooth. Slowly beat in the confectioners' sugar, a cup at a time, until you have a sticky dough. Reserve 1 cup of powdered sugar for kneading. The dough will be very stiff.
  3. Rub your hands thoroughly with butter, and begin kneading the sticky dough. As you knead, the dough will become workable and pliable. Turn the dough out onto a working surface dusted with confectioners' sugar and continue kneading until the fondant is smooth and no longer sticky to the touch, 5 to 10 minutes.
  4. Form the fondant into a ball, wrap it tightly in plastic wrap, and refrigerate overnight. To use, allow the fondant to come to room temperature, and roll it out onto a flat surface dusted with confectioners' sugar.

I made this with MARSHMALLOW FLUFF!!!! I definitely recommend to do it this way! Based on the previous reviews of saying to wait till the melted marshmallows cooled, I skipped the melting the marshmallows and water step and I placed a whole container of marshmallow fluff into the refrigerator over night. The next morning, I sprayed my kitchen aid very well with PAM, dumped the whole container of Marshmallow fluff into the KA and food coloring and confectioner/powdered sugar as needed. This really was not that difficult or messy at all. When the fondant was at a good consistency, I placed it into plastic wrap and into the freezer for about a 1/2 hour. I then rolled it out and it rolled really nicely. I used this fondant to cover a barbie doll cake than I made for my daughter's birthday! I spread a very thin layer of regular frosting onto the cakes surface to make sure the fondant would stick to the cake. It came out great!


I've used a very similar version of this recipe for years. It is WORLDS better than any prepackaged fondant you can buy, in ease of use, in taste, and especially economically. I've never added the extra vanilla, though I've occasionally added different flavoring oils. I've also never used the butter in this recipe, with no problems. A tip: If you need colored fondant, add the color to the hot marshmallow mixture before you start adding sugar. Otherwise you'll have to knead in the color later, which will result in technicolor hands and a potentially off texture. **Edit: Yesterday I used this recipe to make chocolate fondant. I added Americolor chocolate brown color to the melted marshmallows, and I also kneaded in about 1/2 cup sifted cocoa with the confectioner's sugar. After coating with shortening, wrapping in plastic and allowing to sit overnight, it was a bit dry, but water didn't help; I had to knead in some extra shortening to get it to a good texture (which didn't take long). Instead of dusting the countertop with confectioner's sugar when rolling it out, I just greased it with a little bit of shortening - it prevented sticking and gave the fondant a nice shine.


For all you skeptics/"I'm not good enough"/"I can't do it"/doubters out there, YOU CAN DO THIS! It is soooooooo easy. I'm VERY new to cake/cupcake baking/decorating (just started playing around for fun in Oct 08). I made this last night for a legal pad sheet cake (11X15, my very first sheet cake) and it was super easy. I melted the marshmallows and added the water and vanilla...then panicked because I couldn't get it smooth. No prob, just kept nuking at 30 sec intervals. AT THIS POINT, I ADDED GEL FOOD COLORING to get my desired color (soooo much easier than adding at the kneading stage like I did the other time!). I added as much 10X sugar as I could w/a spoon, then turned it onto my HEAVILY GREASED (I use Crisco) counter to knead the rest in. I am impatient, so I attempted to roll it out and use it the same night I made it. Didn't work (however, it would have worked if I'd been using it for cut outs/decorations, just not for covering an entire cake). I put it back in a ball, rubbed some more shortening on it, then wrapped it in plastic wrap and put it in the frig til morning. After letting it warm, I rolled it on a cutting board sprinkled w/corn starch and had no problem getting it on the cake (I simply inverted the cutting board over the cake!). I want to also add that it was INCREDIBLY HUMID when I made this and it STILL worked super well. I'm telling you, give this a try; people will think you are a baking ROCK STAR for very minimal effort! TY for post
