This post is a little out of the ordinary for me, but I wanted to share it because it’s a fantastic way to get your kids in the kitchen!

What kid wouldn’t like to mix and match colors to create something that’s about as close to edible play dough as you can get?! When my daughter was younger, I would give her some of this traditional fondant and some cookie cutters on the kitchen island and it would keep her busy for hours!

And even better than that, it’s a great cake decorating way to make your cakes look professional with hardly any effort on your part!

What is Marshmallow Fondant?

Very simply, it’s marshmallows and powdered sugar. That’s it! You also need to add a little water but that doesn’t count as an ingredient, so seriously… only two ingredients and you could have your first batch of marshmallow fondant!

If you’re cringing right now because you’ve tasted regular fondant before and you can’t stand it, let me assure you that this is different. This is much sweeter and has more of a vanilla taste to it. I still wouldn’t go eating big chunks of it, but it’s perfect for small decorations on a cake or cupcake.

How Do You Make Marshmallow Fondant?

It’s as simple as emptying a bag of mini marshmallows into a large bowl with two tablespoons water. Then microwave them for 30 seconds, remove and stir. Repeat that until you have completely melted and smooth marshmallows.

Then add about 1 cup of powdered sugar to your melted marshmallows and stir. Keep adding small amounts of powdered sugar and stirring in between until you can no longer stir it.

Lightly dust your work surface and your hands with powdered sugar and then turn the contents of the bowl onto the counter. You’re going to knead, knead and knead some more all while adding more powdered sugar until you get a nice smooth disc of fondant that can stretch without tearing.

You will probably be kneading for about 8-10 minutes. You want to keep going till it reaches the consistency of play dough.

Tips for Making Marshmallow Fondant

  • If you’re kneading your fondant and it’s too dry and tearing, add 1/2 tablespoon of water at a time. Keep kneading it in until it reaches the point where it’s no longer tearing or cracking.
  • If you are coloring your fondant all one color, you can add drops of food coloring into the melted marshmallow stage.
  • If you are coloring your fondant in different colors as I did, then you will have to wait until you are done kneading. Then separate your fondant into different pieces, add food coloring and knead until it’s completely combined.marshmallow fondant in 4 colors rolled into a log
  • You will probably want to wear gloves if you are kneading in food coloring because it will stain your hands.
  • You can use the fondant immediately or store it until later.
  • If you are storing it for later, roll your fondant into a ball and then lightly coat the outside with vegetable oil or shortening so it doesn’t dry out. Store in an airtight container that you can remove most of the air from. Air is what will dry out the fondant and make it unusable, so be sure to get as much air out as possible.
  • If stored properly, homemade marshmallow fondant can last for a few months.

This recipe will give you enough to cover 2 8″ round cakes. Or you can cover one tier and use the rest to make decorations with like these camping toppers I made for cupcakes.

It’s so easy to make and only costs a few dollars, but could fool people into thinking you’re a professional cake decorator or give your kids hours of fun!

Either way, it’s a fun recipe to try that’s different from all the others!

In conclusion, this marshmallow fondant recipe is a great way to make a dessert that is both delicious and easy to work with. It is perfect for any occasion and can be customized to fit any taste. So if you are looking for a new and exciting way to make dessert, give marshmallow fondant a try!
