Equipment

Large wire mesh strainer
Large bowl
Microwave safe bowl

Ingredients

  • 1 lb Mini Marshmallows
  • 2 lbs Icing powdered sugar
  • 2 tablespoon water
  • Flavoring optional
  • Cocoa Powder optional
  • Coloring optional.
  • Vegetable Shortening

Instructions

  • Use the wire strainer to "sift" your icing sugar into the large mixing bowl, set aside.
  • Measure water into a microwave safe glass / Pyrex bowl - Mine is about 9" across, 3" deep.
  • Dump the bag of marshmallows into the glass dish - on top of the liquid - and microwave it till melted. I find it's usually 1:35 - 1:45. Don't burn it!
  • Stir the marshmallows/liquid together until smooth - make sure you get ALL of the water incorporated! I grease a butter knife with a little shortening to do this.
  • At this point, add coloring if you plan to. You'll want to color it a bit darker than you want the final color to be.
  • This is also the point you will add your cocoa - sifting it in - if you are making chocolate fondant.
  • I use the Hershey's Dark / Dutch Processed cocoa powder, and just mix it in till it's slightly too dark. I use between ¼- ½ cup of cocoa. If I'm doing a light brown color, I use regular cocoa powder, and less of it.
  • Dump the melted marshmallow mix into the bowl of icing sugar, stirring with the knife until fairly well incorporated.
  • Grease your hands up with some shortening, and knead the fondant for a couple of minutes, till it's no longer sticky. It should use about ⅔ - ¾ of the powdered sugar in the bowl.
  • Turn the fondant out onto a clean, flat surface. Knead it for another minute or so until it is smooth. It should be fairly firm.

Notes

This takes me about 7 minutes from the time I put the marshmallows into the microwave.
Nutrition calculation information is for one whole batch of fondant, which is enough to cover a 10" cake.
