How to Make Sweet and Easy Decorating Fondant for Cakes

Kylyssa is an artist who works in a wide variety of media that has included fondant since 2008. She enjoys creating and sharing sweet tips.


A Home Made Marshmallow Fondant Recipe That's Fun and Easy to Make

Fondant is like edible modeling clay. It can be shaped, colored, cut or molded. It can turn a plain cake into a work of art. This pliable icing used to be something seldom used by amateurs, but with the advent of cake shows, fondant and other culinary ideas once relegated to professionals have moved right into our living rooms. If you've seen Ace of Cakes or Cake Boss you've seen some in use. A baker can make real works of art with the use of a little modeled sugary decoration.

However, commercial, pre-made fondant can be expensive and frankly doesn't taste very good. With some experimentation, much of it very messy, quite unappetizing and downright dangerous, I've arrived at a simple and inexpensive alternative to the commercial version that is surprisingly easy to work with.

This recipe costs under $10 per cake even including the initial outlay for a multicolor box of food coloring. Typically, I spend less than $5 per cake on fondant ingredients, even for cakes with a dozen colors of it!

Home Made Fondant Ingredients

You will need:

  • 1 cup of mini marshmallows, packed tightly
  • 1 - 1.5 cups of powdered sugar
  • 4 teaspoons of water
  • Half a teaspoon of cooking oil cooking oil to grease up your hands and work surface if needed extra powdered sugar for rolling out the icing

One batch makes enough fondant to cover a double layered, eight inch round cake.

Step One: Mix Marshmallows, Food Coloring, and Water

Mix the mini marshmallows with the water in a microwave safe bowl, coating them as evenly as possible with the liquid. If you wish to make a colored finished product, add the food coloring at this point.

Step Two: Microwave with Care

Microwave the mixture for ten seconds or until they first begin to melt. If the marshmallows have not begun melting, microwave in increments of ten seconds until they do. Watch the process closely; you do not want to overcook the marshmallows because their consistency can turn stringy or the mixture can get too hot, creating a sticky burn hazard.

Step Three: Stir the Mixture and Add Cooking Oil

Stir the mixture to check for readiness - if all the lumps are gone once you stir it up for about thirty seconds, it is ready for the next step. If there are still lumps, microwave it again for another ten seconds. Stir until the lumps are gone.

If the color isn't almost twice as deep as you want the final color to be, add more food coloring and stir it in until the mixture is dark enough.

Add the cooking oil and stir it in thoroughly.

If you need to microwave the mixture longer be very, very watchful and use very short increments of time as it can easily be overcooked and become stringy.

Step Four: Stir in Powdered Sugar

Once you are able to stir out all the lumps add the powdered sugar in small batches to the hot marshmallow mixture stirring vigorously. Be very careful as this mixture may be extremely hot and sticky.

Trust me; if you get the mixture too hot it burns like the dickens if you get it stuck to your skin. It may not seem like all the sugar will stir into the marshmallows but I assure you, it will. By the time you've stirred in all the powdered sugar you can with your spoon, it is usually pretty cool to the touch.

It takes a lot of stirring to incorporate the sugar into the melted marshmallows.

Step Five: Kneading

Once you've gotten all the powdered sugar stirred in allow the mixture to cool enough to be touched. Then grease your hands with a cooking oil and knead the mixture until it is smooth and somewhat similar in consistency to Play-Doh. If the fondant feels sticky instead of doughy, continue to add more powdered sugar until it feels doughy. If it feels too grainy try heating it in the microwave for four to six seconds and allow it to cool wrapped tightly in plastic. This should help it to become more like a very viscous liquid than like a bunch of grains of sugar bonded together with goo.

Now you can either use the fondant right away or store it for later use.


How to Make It into Colored Fondant

If you want colored fondant add food coloring with the water before microwaving your marshmallows. Otherwise the coloring comes out streaky and uneven. Use liquid food coloring as part of your 4 teaspoons of water, not in addition to it.

To make a hot pink icing add 20 drops of hot pink food coloring.

To make neon lime green add 20 drops of neon green food coloring.

The food coloring brand I prefer is McCormack which has a neon line great for creating bright colors.

To make chocolate fondant substitute dark cocoa powder for half of the powdered sugar and increase the cooking oil by half a teaspoon.

Rolling out Home Made Fondant: Step One


Lay down sheets of wax paper on your work surface and generously sprinkle them with powdered sugar to prevent the fondant from sticking. I use a tea strainer to to make a more-or-less even layer of powdered sugar.

An alternate method is to liberally grease the waxed paper with cooking oil. Do not combine the two methods.

Rolling out: Step Two


Lay the blob fondant on top of the powdered or greased work surface.

Grease or Sprinkle with Powdered Sugar


Sprinkle fondant liberally with powdered sugar or, if using the oil method, grease its entire exposed surface with a very thin layer of cooking oil.

Sandwich It Between Layers of Waxed Paper


Cover the fondant with another sheet of waxed paper.

Flatten It Evenly


Roll out the fondant with a rolling pin until it's as long as it needs to be to cover your cake.

Add More Powdered Sugar or Vegetable Oil and Re-Cover


Lift the top sheet of waxed paper and sprinkle powdered sugar onto the fondant. Then, flip the fondant over on the waxed paper and generously sprinkle it with more powdered sugar or rub with cooking oil if using the oil method.

Flavored Fondant

To make it flavored add a few drops of food flavoring such as almond or vanilla extract or peppermint or lemon oil before adding the powdered sugar to the melted marshmallows. LorAnn candy-flavoring oils also work great and taste amazing.

Rolling out Home Made Fondant: Step Seven

Re-cover the fondant with waxed paper and roll it out in the other direction until it is wide enough to cover your cake.

Now it can be applied to your cake!

What to Do When It Sticks


How to Salvage Stuck Fondant

Don't panic, this can be fixed!

If the fondant sticks to the waxed paper, gently slide it up with a metal spatula. Then you can either powder it and flip it over, giving it a few gentle passes with a rolling pin to flatten it out or simply apply it with the "good" side up on the cake.

If all else fails you can wad it back up, spritz it with a little water and roll it out all over again, starting from the beginning. If you do this too many times, however, it will start to get a bit stiff and crumbly.

And Now It Is Ready to Use


Once you have a big, flat sheet of fondant you can use it to carefully cover your cake. I recommend using a traditional frosting in a light color to serve as an adhesive before applying it. This recipe makes more than enough to cover an 8-9" double-layer round cake or a similar surface area.

You can either dust off the excess powdered sugar with a pastry brush for a matte finish or give it a light mist spray of water to melt the sugar in and give it a shiny look. Icing rolled out with cooking oil automatically gives it a very smooth, shiny finish.

Storing It

Home made marshmallow fondant can be stored in any airtight container for several days at room temperature or for several weeks in the fridge. If refrigerated, you can either use the heat of your hands to soften it before use or put it in the microwave for several seconds set on defrost.

Shaping It


To shape the decorations you can either mold them with your hands as if out of clay, you can cut them out with cookie cutters, or use a knife to cut out custom shapes as I did for the tiger cake. An X-acto knife or other precision tip craft knife coated with cooking oil or non-stick cooking spray on its cutting blade works very well to cut out designs.

Prevent Fondant from Sticking in Cutters

Spray cutters such as alphabet cutters and shape cutters with non-stick cooking spray before use to prevent the fondant or gumpastefrom getting stuck in them. Wipe and re-apply non-stick spray between cut-outs on mini cutters.

thanks for sharing!!!

Margaret Schindel from Massachusetts on March 17, 2012:

Wow - this is by far the easiest-looking fondant recipe I've ever seen! Thank you so much for sharing it and for all the helpful tips you've included.

Kylyssa Shay (author) from Overlooking a meadow near Grand Rapids, Michigan, USA on March 01, 2012:

@anonymous: Yes! Spray some cooking spray on a pair of kitchen scissors and cut standard marshmallows into thirds or quarters to use them in this recipe. Compact the cut marshmallows into the measuring cup to be sure you get enough into your batch of fondant. Cut marshmallows seem to cook just a tad more quickly than mini marshmallows so watch the cooking process very carefully.

anonymous on March 01, 2012:

Can you use large marshmallows if you cut them into smaller pieces?

ChrissLJ on December 18, 2011:

As a vegetarian, I can't eat marshmallows. (They contain gelatin.) Many marshmallow creams though are veg friendly and don't contain gelatin, so I wonder if they would work in the recipe. Have you ever tried it?

Kylyssa Shay (author) from Overlooking a meadow near Grand Rapids, Michigan, USA on November 23, 2011:

@anonymous: It makes enough fondant to cover a double-layer eight inch round cake.
