Homemade Marshmallow FondantTime has been flying right by!! I can’t believe Christmas is THIS TUESDAY! Yikes. My sister and her family arrive today and my husband finally flies in on Saturday {yippee!!}. So far, I’ve happily eaten a TON of my parents cooking, made gingerbread houses, gotten together with friends, watched a lot of Friends episodes {love them!}, gotten a little shopping in, tried to convince my daughter that sitting on Santa’s lap really isn’t that scary, snuggled my new niece and hung out with my family. SO FUN. I’m glad I’m making the most of this vacation as best as I can!

In other news: this baby has been doing back flips nonstop. I think he enjoys Canada….and/or all this food I’m eating! I actually felt him kicking up in between my ribs from the outside! My husband was a little bummed he missed it, but there will be plenty of other kicks to be felt. My 3 year old felt him kicking her hand briefly to which she replied “we shouldn’t kick others. He should apologize”. It was fun explaining THAT one to her. Haha!

Anyways, this recipe is brought to you by my older, wiser, Idaho-living, cake-decorating sister. After you make a bunch of wedding cakes like she does, storebought fondant gets expensive…and is also super gross. Whenever you go to a wedding, all the guests peel the fondant off because you don’t want to ruin the flavor of the cake! I know I do…

Well, this marshmallow fondant is easy to make, costs a quarter of the price and tastes a million times better! Honest to goodness, I could eat it straight. And it takes about 10 minutes to make. Basically, it’s super sweet melty marshmallows all wrapped around a cake. Seriously yummy.

Here’s how you do it:

MarshmallowsStart by measuring out some marshmallows.

Adding ingredients to marshmallowsAdd in some water–like 1/2 tablespoons…not a lot!

Making marshmallow fluff in the microwaveAnd microwave it until its all melted.

Melted marshmallowsLike so!

Powdered sugar to melted marshmallowsSift in about 2 cups of powdered sugar and stir.

Marshmallow mixture on a roulpatOnce it gets thick and hard to stir, pour it onto your clean work surface and get kneading! It’ll be warm and sticky to start with, but the more powdered sugar you knead into it the easier is becomes to work with.

Marshmallow FondantAfter kneading in another 2-3 cups, you should have a smooth ball of fondant. It shouldn’t be sticky at all anymore and pretty much cooled. Store this in plastic wrap at room temperature until you’re ready to use.

Marshmallow FondantI rolled some of this out and covered a 2 layer 8 inch cake for the holidays….nothing special. I wrapped the bottom with blue ribbon and let my little one color the top with these fun Wilton Edible Markers that I have fallen in love with. They make such a cute presentation! I’d recommend refrigerating the cake before coloring…or not have a 3 year old do all the decorating–LOL! 🙂 The word ‘gentle’ can only be said so many times….Overall, I fell in love with how this cake turned out…just because I think it’s adorable and would make such a cute present for the grandparents or neighbors.

    How would you make this recipe colored? Add coloring to the marshmallows before melting? After? Can you add color? Would it just be light colors?

    Just saw this recipe via Pinterest! Excited to try it! Have you used the other Silpat like products by Demarle? My favorites are the large round mold, which you could microwave your marshmallows in and they would not stick to the bowl! And the mini muffin – no greasing the muffin molds and everything pops right out. All made and work the same way as the silpat and roul pat. Check them out www.mydemarleathome.com/MelanieHolan

    Hey Lauren,

    I have never used a silpat or made foudant. I am starting to do alot of baking and I am learning alot. This would help me out!

    Thanks for the opportunity!

    Man I need those. I’ve been making marshmallow fondant for years! Yes it tastes so much better and is way cheaper. The recipe I use, you smear crisco all over the counter and knead and knead, while getting a good arm workout. 🙂 In my experience if your making a cake for a party you shouldn’t refridgerate it though, when it comes out it of the fridge, the the cake sweat, and possibly the fondant will start to fall off, not fun. However, I do refridgerate the fondant untill ready to use, it lasts a looooooog time in the fridge, which is great cuz you can make it way in advance unlike buttercream 🙁

    I love your daughter’s decorating technique! I see that she included the whole family… and a crab? Also, she’s already being a good big sister and teaching her little brother to mind his manners. 😀

    Merry Christmas!

    All the directions look simple. Most recipes now say use silplat. I don’t have one and would love to get one. Expensive and beyond my budget. Trying to get into baking more. Doing it for one is a little bit of a chore and puts me off sometimes.

    This fondant is sooooo much better than traditional fondant. Whenever I make it, my kids end up grabbing chunks of it to eat straight – it’s that good! I’ve also used the colored/flavored marshmallows when I am adding color to the fondant.

    What a great recipe! I’ve never attempted fondant. Sure makes a
    beautiful base to decorate. I’ve never used a Silpat. Sounds like a
    wonderful invention!

    Oh, I have been wanting a Silpat mat for months now, ever since I heard of them. This is the best giveaway! Oh and this recipe looks tasty. This summer I tasted fondant for the first time. It was too bad although the texture was not what I was expecting. So now I will have to try making some myself. My MIL used to decorate cakes and make her own so I’ll have to send her the recipe too.

    Oh and I get email updates.

    YUM! i am excited to try this because i love the look of fondant, but just cannot stand to eat it! That makes me rule out using it all together because it feels so wasteful. Ive also been wanting to buy a silpat! Maybe I’ll get one for Christmas this year! 🙂
