Easy Marshmallow Fondant

Have you ever seen those beautiful cakes, cupcakes, and cookies at a fancy bakery, and wondered how they made them look so perfect? The answer is fondant! Fondant is a thick sugar paste that’s used in pastry decorating and is easier and more stable to use for decorations than buttercream or other icings.

Unlike other regular types of frosting, fondant creates a very smooth surface on your favorite baked goods that you’re trying to decorate.  This marshmallow fondant not only tastes great, but it’s easy to make at home too. It’s the perfect way to take your decorating up a notch!

How to Make Marshmallow Fondant

Marshmallow fondant is surprisingly easy to make! You’ll need the following ingredients; mini marshmallows, water, powdered sugar, and vanilla extract, plus gel food colors (I like the Wilton brand) if you want to color it different colors and then you’re ready to go.

  1. Add the marshmallows to a microwave-safe bowl and then sprinkle the water over the top of the marshmallows
  2. Heat in the microwave on high for 30 seconds and then stir
  3. Continue to heat in 30 second increments until the marshmallows have completely melted
  4. Stir in the vanilla with the melted marshmallow
  5. Add half of the powdered sugar and then stir until combined – note that it will be very sticky and hard to stir
  6. Continue to add in the remaining powdered sugar until the mixture has the consistency of playdough
  7. If you want to color the fondant, separate the amount you want to color and add in a few drops of the gel food color and then knead the dough into the fondant

Tips For Making Marshmallow Fondant

  • It’s very important to use gel food coloring (as opposed to water-based food coloring) for the best results. You can buy it at most grocery stores, and I’ve found a wide selection of gel food coloring at Walmart in the cake decorating section.
  • I found it easiest to knead the food coloring in while wearing gloves that I dusted in powdered sugar. It will take a little work to get it evenly distributed, but keep working and it will come together.
  • If the fondant is too sticky, you can add a little more powdered sugar to the mix

How To Use Marshmallow Fondant

So now that you have your colorful marshmallow fondant, what can you make with it? The sky is the limit! Just like play dough, it’s easy to roll out and shape in any number of ways, which makes it perfect for decorating cakes, cupcakes, and cookies.

One of my favorite and easy ways to use marshmallow fondant is as a topper for sugar cookies. Just roll out the fondant, cut it with the same cookie cutters as you used for the cookies, and attach it to the top of the cookie with a small amount of buttercream.

And voila! A perfectly frosted cookie that tastes delicious and looks like it came from a bakery. It doesn’t get easier than that! You can make the cookies as simple or elaborate as you like. If you’re looking for a great recipe to use, this Sugar Cookie Recipe is one of our favorites!

How To Store Marshmallow Fondant

If you’re making the cookies ahead of time, be sure to store them at room temperature, in an airtight container, to prevent the fondant from drying out. If stored this way, the cookies should stay fresh for about 3 to 5 days.  Enjoy using fondant to make all of your baked goods more beautiful!

If after decorating your cookies or cupcakes you have leftover marshmallow fondant you can store it and save it to use for another time.  Marshmallow fondant can dry out quickly, so I like to first wrap it in plastic wrap and then place it into an airtight container for storage.  Stored at room temperature (do not refrigerate or freeze it) the fondant should stay fresh for about 2 months.
