How to Make Marshmallow Fondant


Love the look of fondant but think, I could never do that? Well, you’re wrong!  Making a cake with fondant icing really isn’t all that hard, but if you’re going to attempt it then I highly suggest making your own fondant.  Yes, I know, just one more thing to do, but it will totally be worth it.  You can save some money and this recipe for fondant tastes so much better than the store-bought fondant.

My husband and I are huge fans of the show Cake Boss and after watching the first two seasons, we decided to make a cake with fondant icing for Rylan’s third birthday.  My husband researches everything and Amazon is his go-to-guy so he immediately began searching for some fondant to buy off of Amazon.  After minutes of searching, he wasn’t satisfied with any of the reviews of the fondant being sold so he began searching for fondant recipes and came across this one on We tried it and it works and tastes great!  We didn’t have to alter it a bit!

  • 1/4 cup butter
  • 1 (16 ounce) package miniature marshmallows
  • 4 tablespoons water
  • 1 teaspoon vanilla extract
  • 2 pounds powdered sugar, divided
Game Plan:

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.

3. Carefully stir the water and vanilla extract into the hot marshmallows, and stir until the mixture is smooth.

4. Slowly beat in the powdered 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.

5. Rub your hands thoroughly with butter, and begin kneading the sticky dough. As you knead, the dough will become workable and pliable.

7. 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.

Notice the hands in the photos are manly– that’s my husband; I guess you could say he’s MY cake boss.  I let him take the lead when it comes to making fondant cakes and am so glad I don’t have to make cakes on my own anymore.  Want your husband to get involved?  Watch some episodes of Cake Boss and who knows, he may just be inspired– worked for mine!
