This homemade fondant recipe can be made in less than 10 minutes and will change your life. I have been making LMF (Liz's Marshmallow Fondant) since 2010, and what sets it apart from regular marshmallow fondant is the addition of a small amount of store-bought fondant. That one extra step adds the gelatin and elasticity that marshmallow alone cannot replicate, so you get a batch that stretches like taffy, covers cakes without cracking, tearing, or elephant skin, and actually tastes delicious. I use this to cover everything from simple birthday cakes to tiered wedding cakes, and it is the recipe that turned my most skeptical clients into fondant converts.

Why This Fondant Recipe Works
- Marshmallows build the structure. Marshmallows are made of sugar and gelatin, which gives LMF its base elasticity and holds everything together. The sugar keeps it sweet and pliable, while the gelatin is what allows it to stretch without breaking.
- Store-bought fondant is the secret weapon. Adding a small amount of pre-made fondant is what separates LMF from every other marshmallow fondant recipe. Store-bought fondant contains additional gums and stabilizers that give the finished batch a level of stretch and smoothness that marshmallow fondant alone simply cannot achieve. You are essentially upgrading a cheap product with a homemade one to get the best of both.
- Cheap marshmallows work better than name brands. Store-brand marshmallows have a softer, airier texture that melts down smoothly and incorporates easily. Name brands like Jet-Puff tend to be denser and drier, which makes the fondant stiffer and harder to work with.
- Vegetable shortening keeps it from drying out. Shortening coats the sugar molecules and slows down moisture loss, which means your fondant stays soft and workable longer without cracking or developing elephant skin on your cake.
- Warmth is everything. This fondant performs best when it is warm. Heat relaxes the gelatin structure and makes the dough stretchy and forgiving. Cold fondant tightens up and tears, which is why you always knead it well and reheat before using.
My marshmallow fondant has been my secret weapon for years, and now it can be yours, too.
Fondant Ingredients
Making LMF only requires five ingredients, and most of them are easy to find at any grocery or craft store. Check the notes at the bottom of the recipe card for brand recommendations and substitutions.
- Marshmallows: Marshmallows are the base of this recipe and do most of the heavy lifting. They are made of sugar and gelatin, which gives the fondant its soft, pliable structure and natural elasticity. Store-brand marshmallows like WinCo, Hy-Top, Aldi, or Campfire work best because they are softer and melt down more smoothly than denser name-brand options like Jet-Puff.
- Powdered Sugar: Powdered sugar is what gives the fondant its body and workable texture. It absorbs into the melted marshmallow mixture and firms everything up into a dough you can knead and roll. You may not need every last bit depending on your climate, so add it gradually and stop when the dough feels smooth and slightly tacky.
- Store-Bought Fondant: This is the ingredient that makes LMF different from every other marshmallow fondant recipe. Adding Wilton or Satin Ice fondant introduces extra gums and stabilizers that dramatically improve stretch and smoothness. You are essentially using a small amount of a cheap product to upgrade your whole batch into something far better than either one would be on its own.
- Vegetable Shortening: Shortening coats the sugar molecules and slows down moisture loss, keeping the fondant soft and pliable. It also lubricates your hands and work surface during kneading so the dough does not stick or tear. Do not substitute butter here - the water content in butter can affect the texture.
- Warm Water: A small amount of warm water helps release the melted marshmallows from the bowl and loosens the mixture just enough to incorporate the powdered sugar smoothly. If you are making a dark-colored fondant, replace one tablespoon of water with one tablespoon of gel food color to get a head start on the color during mixing.
How To Make Fondant Step-By-Step
Before you start, coat your hands and work surface lightly with vegetable shortening. This prevents sticking during kneading and makes the whole process much easier to manage.
- Sift your powdered sugar into a large bowl and set it aside. Sifting prevents lumps in the finished fondant, which can show through on a cake.
- Place your vegetable shortening into the bowl of your stand mixer fitted with the dough hook. You do not need to mix it yet, it will incorporate on its own once the marshmallows go in.
- Heat your marshmallows in a microwave-safe bowl in 30-second bursts, stirring between each burst, until they are completely melted and glossy. They should look like a thick, sticky white lava.
- Pour your warm water over the top to help release them from the bowl, then pour everything into the mixer bowl with the shortening.
- Immediately add the melted marshmallows to the stand mixer with the vegetable shortening and the hook attachment.
- Turn the mixer to the lowest speed and begin adding your powdered sugar one cup at a time. It will look rough and shaggy at first; that is completely normal. Keep adding sugar and mixing until the dough is pulling away from the sides of the bowl and looks smooth and slightly sticky, about 5 minutes.
- Coat your fingers in shortening and pull the fondant off the dough hook. Scrape the mixture out of the bowl and into your remaining powdered sugar.
This is also the point you would add in food coloring if you want to color your fondant.
- Microwave your store-bought fondant for 30 to 40 seconds until it is warm and very soft.
- Scoop the fondant mixture out of the stand mixer bowl onto your workbench with extra powdered sugar to prevent sticking.
- Knead everything together until the powdered sugar and store-bought fondant are fully incorporated. You may not need every last bit of powdered sugar, stop when the dough feels smooth, pliable, and slightly tacky but not sticky. If it feels too stiff, microwave the whole batch for 20 to 30 seconds to soften it back up.
- Once combined, pull the fondant like taffy, stretching it out and folding it back on itself repeatedly. When it is ready, it will stretch several inches without tearing and feel silky and elastic. If it is still tearing, it needs more heat, microwave for 30 seconds and keep pulling.
To store: Wrap tightly in plastic wrap and place in a zip-lock bag at room temperature. LMF will keep for several months. Always reheat and knead well before using again.
Before applying fondant, frost your cake with a layer of white chocolate ganache - it sets firm enough to give the fondant a perfectly smooth surface to adhere to.
Common Mistakes To Avoid
- Using name-brand marshmallows. Brands like Jet-Puff are denser and drier than store-brand marshmallows, which makes the finished fondant stiffer and harder to work with. Stick to WinCo, Hy-Top, Aldi, or Campfire for the best texture and the lowest cost.
- Not heating the marshmallows enough. The marshmallows need to be completely melted and glossy before they go into the mixer. If there are any unmelted lumps, they will create hard spots in your fondant that show up on the surface of your cake. Heat in short bursts and stir between each one until the mixture is fully smooth.
- Adding the powdered sugar too fast. Dumping in all the sugar at once causes it to clump and mix unevenly. Add it one cup at a time on the lowest mixer speed and let it fully incorporate before adding more.
- Skipping the store-bought fondant. This is the step most people want to leave out, but it is the one that makes LMF work. Without it, the fondant will not have enough elasticity and will be more likely to tear when covering a cake. Do not skip it.
- Using cold fondant. Cold fondant is stiff and will crack or tear as soon as you start rolling it. Always microwave and knead your fondant thoroughly before using it, even if you just made it and it has cooled down. It should feel warm and stretchy before it goes anywhere near a cake.
- Covering a warm cake. The cake and its buttercream or ganache coating need to be fully chilled and firm before you cover it with fondant. A soft surface will not support the weight of the fondant and you will get bumps, bulges, and sliding.
- Rolling the fondant too thin or too thick. Too thin and it will tear during application. Too thick and it will look heavy and be hard to get sharp edges. Aim for about ⅛ inch, which gives you enough strength to cover the cake without the fondant looking clunky.
- Using too much food coloring. Liquid food coloring adds too much moisture and can make your fondant sticky and pocked with tiny holes. Always use gel food coloring, and for deep colors like red or black, add the color during the mixing process rather than kneading it in afterward.
If you want something more sculptural, try my modeling chocolate recipe instead - it holds fine details much better for sculpting.
Fondant Recipe FAQs
I know it seems counterintuitive, but this is the step that makes LMF better than any other marshmallow fondant recipe out there. Marshmallow fondant on its own lacks the elasticity you need to cover a cake cleanly. Store-bought fondant contains gums and stabilizers that dramatically improve how the finished batch stretches and handles. By adding it to your homemade batch you are essentially upgrading a cheap, average product into something far better. Think of it like adding a small amount of high-quality chocolate to a basic sauce. It changes everything.
Nine times out of ten, tearing and cracking come down to temperature. Cold fondant is stiff and unforgiving, so always microwave it until it is warm and knead it well before you start rolling. If it is still tearing after that, it may need more shortening worked in. Cracking on the cake usually means the buttercream underneath was too soft or the fondant was rolled too thin. Aim for ⅛ inch thickness and make sure your cake is fully chilled before covering.
Wrap your fondant tightly in plastic wrap, place it in a zip-lock bag, and store it at room temperature. Do not refrigerate it. The moisture in the fridge will make it sticky and affect the texture. Stored properly, LMF will keep for several months. Before using it again, microwave it for 20 to 30 seconds and knead it well until it is warm and stretchy.
Always use gel food coloring, not liquid. Liquid coloring adds too much moisture and can make your fondant sticky or pocked with tiny holes. For light pastel colors, you can knead the color in after the fondant is made. For deep or dark colors like red or black, add the gel color during the mixing process while the marshmallows are still warm. This gives the color time to distribute evenly and prevents you from overworking the fondant trying to knead in a large amount of color later.
Yes, you can make LMF by hand, but it is a workout. Mix the melted marshmallows and shortening together in a large bowl, then add the powdered sugar gradually and knead it in with your hands. Make sure your hands are coated in vegetable shortening throughout the process. It will take about 10 to 15 minutes of kneading to get the same smooth, stretchy result you would get from a mixer.
Yes! My friend Danette developed a version called DKF (Danette's Kosher Fondant) that uses marshmallow fluff instead of regular marshmallows, making it gelatin-free and kosher. It works just as well as LMF and follows a nearly identical process.

Recipe
Ingredients
Ingredients
- 32 oz powdered sugar sifted (also called icing sugar, confectionary sugar)
- 16 oz marshmallows WinCo, Hy-Top, Aldi, and Campfire brands work best
- 20 oz Wilton fondant Satin Ice fondant will also work
- 2 tablespoon warm water For dark colors, use 1 tablespoon warm water and 1 tablespoon food color gel
- 4 oz vegetable shortening Also called white vegetable fat, trex, copha
Instructions
How to make fondant
- Sift the powdered sugar and set aside in a large bowl.
- Place vegetable shortening in a stand mixer bowl.
- Heat marshmallows for 40 seconds in the microwave on high (or on stove top). Stir with spoon.
- Place marshmallows back into microwave and heat for another 30 seconds (or on stove top). Stir with spoon.
- Heat marshmallows (last time!) for 30 seconds in the microwave (or on stove top).Marshmallows should be ooey-gooey at this point and ready to be added to the mixer bowl. Pour your water on top of the marshmallows to get them to release from the sides of the bowl. Pour into bowl with vegetable shortening
- Turn stand mixer on lowest setting (setting 1 on Kitchenaid stand mixers) with dough hook attachmentAdd in half of your sifted powdered sugar, a measuring cup at a time, and let mix for 2 minutes. It will be really rough looking at first
- Don't stop mixing until it's sticking to the sides of the bowl and looks smooth. Add in another cup of powdered sugar.
- Pull fondant off the dough hook attachment by putting vegetable shortening on your fingers and pulling it off the hook.
- Take the soft mixture out of the bowl and put it into the large bowl with the rest of the powdered sugar.
- Warm the Wilton fondant in the microwave for 40 seconds and add to the large bowl with the powdered sugar and marshmallow mix.
- Knead until powdered sugar, marshmallows and Wilton fondant is mostly incorporated. You may not use all of the powdered sugar depending on your climate and that is completely fine.
- Pull fondant like taffy until it is stretchy and smooth. If there are still rough spots or it's tearing, put everything back in the microwave for 30-40 seconds to make it really hot and pull like taffy with shortening on your hands until it pulls without breaking
- Store in a zip-lock bag at room temperature. Fondant will keep for months in a zip-lock bag. To use again, reheat and knead well until stretchy before each use. You can add color as desired but for dark colors, you should add them during the mixing process or you could get a sticky mess.

Notes
- To store: Wrap tightly in plastic wrap and seal in a zip-lock bag at room temperature. Do not refrigerate. LMF keeps for several months stored this way.
- To reuse: Microwave for 20 to 30 seconds and knead well with shortening-coated hands until warm and stretchy before rolling.
- If your fondant is too stiff: Microwave the whole batch for 20 to 30 seconds and pull it like taffy with shortening on your hands until it loosens up.
- If your fondant is too sticky: Knead in a little more powdered sugar a tablespoon at a time until it reaches the right consistency.
- For dark colors like black or red: Add gel food coloring during the mixing process while the marshmallows are still warm for the most even color distribution.
- Coverage: One batch covers approximately a 10-8-6 inch tiered cake when rolled to ⅛ inch thickness.

Hi I wanted to know if you can refrigerate this fondant?
The Sugar Geek Show says
Yes you can
Krish says
Hi i want to make vegan fondant which means i can only use Dandies marshmallow. Will i be able to make it using this and vegan marshmallow fluff?
Thank you
The Sugar Geek Show says
I really don't know, I am not an expert in vegan recipes 🙂
Jenn says
Love this recipe!! I made it last night! So easy and tastes amazing!! thanks so much!!! I'm new to using fondant and I did a few things differently in the recipe (ie not.sifting icing sugar) and I only did half the recipe as well and it made a lot!!! And it still turned out AMAZING ??? so thank you !!
Marcus says
Hi i'm baking a cake for my mom for mothers day/my birthday they fall on the same day this year but i don't have a table scale of any sorts. I have the measurements to the powdered sugar and marshmallows but I cant seem to find the measurements to the fondant. Also what do I do since I don't have the hook attachment. Can you help me please i need to plan ahead.
The Sugar Geek Show says
Be careful with not using a scale, there is a big chance your fondant will not turn out. I would suggest just buying the fondant if you can't use a scale
Tiffany McMillan says
I'm making your fondant for some decorations on my niece's 1st birthday cake before and I'm not sure if I used enough water. Your recipe says 2 tbsp and your vid says 3 tbsp. I used 2, and it's a little dryer than don't know if I need to add a little more water to it or if I can.. If it's dry still do I just heat it up and knead it until it isn't? Thank you!
The Sugar Geek Show says
You can def add more water if it seems dry. This recipe has been updated for the new Wilton fondant which is a bit softer than the older stuff but if you're in a dry area and need more water, totally ok.
Nichole says
I’m making a spongebob tier cake for my sons bday in a few weeks. Excited to try this recipe. I’ve never really worked much with fondant. There are characters and seaweed and coral.....etc. Will this hold up ok if I make its days to a week in advance? Like make it and color it and have the shapes and characters pre made and ready for when I make the cake later on. Should I store in an airtight container or ziplock bag at room temp? Thanks a million!!
The Sugar Geek Show says
Yes I have used LMF for covering cakes and making figures. I add about 1 tsp of tylose powder to 1 cup of fondant and mix it together to make it stiffer 🙂 You can store at room temperature.
Rebecca says
Can the fondant covered cake be left out room temperature or is it better to refrigerate? If refrigerate, how long take out before serving? Thank you.
Sora Strife says
Hi, I'm trying to make this in a few weeks but I don't have a stand mixer or the money for one, can a hand-held mixer be used instead? (I know it'll probably kill my hand, but if I can I will.)
The Sugar Geek Show says
It will kill your hand mixer. You can do it by hand but it requires a lot of pulling and stretching to get it to the right consistency
Denise says
New to fondant-
Can i use this with molds? I want to use the baby mold for a baby shower and was researching fondant and gumpaste (50/50)
If i can make and use what do you suggest ?
The Sugar Geek Show says
Yes you can, I add a little tylose powder to my fondant (about 1 tsp per cup of fondant) to stiffen it up a bit.
Chastity Hart says
If I'm making the cakes the night before with buttercream followed by fondant finish, how should I store the cakes? I was told not to put mmf in the refrigerator
The Sugar Geek Show says
ALWAYS chill your cakes. Always. The fondant will get a tiny bit sticky but it does not hurt the cake
Jenn says
I love your recipe and made it a few weeks ago for my daughter's cake. it was white. today I need to make a yellow bus cake for my son (along with many other colours). Can I simply add food colouring to the batch of white I made for my daughter a few weeks ago? or do I have to make it from start again? I bought some yellow store bought fondant. can I incorporate that into my white homemade fondant along with some food colouring? please advise!
The Sugar Geek Show says
Yes you can color previously made fondant any color you like except dark colors like dark blue, black, purple or red
Jenn says
I made your recipe two weeks ago for my daughter's bday. I saved the remainder of the white fondant in a tight bag like you suggested. I have to make a bus cake doe my son tomorrow. do you suggest I add food colouring to the already made fondant? I also bought 500 grams of store bought yellow but the problem is I need 1.5 kg of yellow fondant. do I simply mix the store bought yellow into my own 1 kg?
please advise!
The Sugar Geek Show says
Yes you can color previously made fondant and yes you can mix fondant together.
Holly McNamara says
Hi, I am going to be making an all-white wedding cake in the next few months, and I'm going to do a few practise runs with your LMF fondant recipe.
How white is your fondant? Is it whiteish-yellow colour? Is there a way I can "whiten" up the fondant to make it a really stark-white colour?
Thank you in advance!
The Sugar Geek Show says
It depends on the marshmallows you use but yes you can add white food coloring to make it whiter
Annie says
Is cost the only reason you would not use pre-colored fondant? I have some pre-colored Wilton that I got on clearance and I'm wondering if there's any reason to not use them in this recipe. Thank you so much!
The Sugar Geek Show says
You can use it but I'm not 100% sure it will work the same 😀 I always use white
alyssa piraux says
I LOVE YOUR FONDANT RECIPE!!!!! I just need to know how much you fondant will cover on the cake I´m making. I´m making a 12 inch, a 10 inch cake, a rice krispie treat ball that needs to be covered in fondant and a little peice of cardboard that needs to be covered with fondant. Will that cover that much cake? If I do maske to batches will It be to much?
The Sugar Geek Show says
I would do a double batch for that much 🙂
