Hi Bold Bakers!

Have you ever heard me say I’m not a cake decorator? I mean at all! Over 15-plus-years as a professional pastry chef, I was rarely in the position where I had to decorate a cake — never mind covering the thing in fondant.

So, why make marshmallow fondant? More traditional rolled fondant recipes require a few more ingredients and you more than likely won’t have them on hand. Marshmallow Fondant is a bag of marshmallows and icing sugar, That’s all you need.

Making your own fondant is inexpensive and fast. I have a great tip on fondant making and coloring on this post for my traditional Fondant recipe.

The Difference Between Marshmallow Fondant And Regular Fondant

Actually, there is really very little difference between marshmallow fondant and traditional fondant when it comes to the ingredients in them. Although marshmallow fondant is just 3 ingredients, and traditional fondant is many more, they are basically made up of the same things.

Marshmallows fondant is quicker and easier to make because the first step is already done for you when you use marshmallows that are already made. Basically, all you need to do is melt down the marshmallows, then add a little water and powdered sugar to get it to the right consistency. If you are new to cake decorating and are starting out, I strongly recommend marshmallow fondant over traditional fondant.

From start to finish I just find it so much easier to work with!

What You Need to Make Your Own Marshmallow Fondant

• 1 bag of mini marshmallows
• Water
• Powdered Sugar
• Flavorless Oil
• A Kitchen Mixer (see also how to make by hand)

How To Make Your Own Marshmallow Fondant

Quick and easy, with very few ingredients — that’s how! Get the full recipe with measurements on the page down below):

1. First, you need to melt your marshmallows. Pour your big bag of marshmallows into a microwave-safe bowl, add a little bit of water, and put it in the microwave until melted.
2. Once melted, you add in your icing sugar (recipe measurement below!), and you mix — you can do this by hand, but it will take some elbow grease for sure.
3. After the fondant begins to come together, you drop it onto a well-oiled surface and you knead (and add some more icing sugar) until it’s nice and smooth!
4. Once it’s kneaded, you can then add any color you’d like to it.

How To Store Marshmallow Fondant

To store Fondant and use at a later date, cover it in a little vegetable oil (like below) and store it in an airtight bag. The less air the better so your fondant doesn’t dry out.

Also, you can always use your leftover fondant to make Homemade Sprinkles. And you can make your own Homemade Marshmallows too!

How to Decorate a Cake with Fondant?

1. Cover your cake in a thin layer of buttercream frosting to create a crumb coat. For more info check out my How to Do A Crumb Coat.
2. Roll out marshmallow fondant on a surface dusted with powdered sugar or cornstarch. If your fondant is hard you can microwave it for a few seconds to soften it so it is easy to roll.
3. Using your rolling pin gently drape the fondant over the cake
4. Using your hands press and shape the fondant to the sides of the cake until smooth.
5. Cut off any excess fondant. Tuck what remains under the cake and smooth it out to look flush.
