Marshmallow Fondant




About: I am a stay at home mother who loves making cool things to entertain my family and improve our lives. What more is there to say?

I am in love with Marshmallow Fondant. This stuff is like delicious Sculpey. It is ridiculously easy to make and incredibly versatile.

Step 1: Ingredients!

You will need:

1 lb (16oz) of Mini Marshmallows
2lb bag Confectioners Sugar (Sifted, to prevent lumps)
4 tablespoons of water
3/4 cup of Vegetable Shortening
Food coloring and/or flavoring (optional)*

*I personally prefer to paint the fondant with food coloring, rather than mix it in.

Step 2: Melt 'em

Mix water and marshmallows in a microwave safe bowl. Microwave in 30 second increments, stirring in between, until completely melted (approximately 2 1/2 minutes).

If you are using food coloring or flavoring add them to the melted marshmallows for easy mixing. You can knead in coloring later but it makes an awful mess.

Step 3: Mix 'em

This is an excellent time to physically work out any frustrations you may have.

Once the Marshmallows are melted, sift and mix in 3/4 of your powdered sugar. Mix together with a fork and once the mixture gets stiff coat your hands liberally with vegetable shortening (if it looks like too much you have just enough) and knead the mix like bread dough. As the mix gets sticky, reapply your shortening.

*Be careful, the marshmallow will be hot and if it sticks to your hands it will burn the expletive out of you*

After you have worked all the powdered sugar into your fondant grease up your counter with some vegetable shortening and knead in the remaining 1/4 powdered sugar. Work quickly, it is easiest to knead/mix while the fondant is still warm.

Step 4: Fondant

Once you have incorporated all the powdered sugar you should have a fondant that is smooth, pliable, and does not tear too easily. You can use it right away but I recommend letting it refrigerate over night. This helps get rid of any little powdered sugar lumps that might ruin the smooth appearance of the fondant.

If you are going to store your fondant before use grease it up to prevent sticking or drying out. This fondant will keep for a couple weeks properly refrigerated.

Also, be sure to bring the fondant  to room temperature before rolling or molding. (I always nuke it for 15 seconds to make rolling easier)

Step 5: Get Creative

Now you have fondant! The sky is the limit with this stuff. It not only gives cakes a beautiful satin finish but it is ideal for making creative themed confections.

    Thanks for posting this recipe along with the detailed instructions. My husband and son had to bake and decorate a cake for Boy Scouts, and let's just say that they have no talent for using traditional icing. Frankly, I'm not much better, but I couldn't have helped with it, anyway. My son wanted to do a Portal-themed cake, and someone on Instructables posted an awesome one, but it looked a bit out of my fellows' league. She did post a link to your Instructable, though. I never knew about marshmallow fondant, much less that it was so easy to make and to use. (Not to mention fun!) I wasn't allowed to help with the cake, but I figured that since they could use pre-made frosting and other items, the pre-made fondant would be okay. My husband already took off for the banquet with the cake, or I'd post a picture. Again, great job!

    You didn't leave it out. It says right there in the materials section:
    " 2LB bag confectioners sugar ( sifted to prevent lumps) "

    And about how much do you think you would be able to cover with one batch? Because I need to have enough of one color because I will never be able to replicate the color again.

    Great instructable too! I have tried a few recipes without marshmallows and they never work.

    I have worked with store bought fondant to make detailed people figures - is the home made fondant as easy to work with? I am worried it might be sticky or a little sloppy? The people figures I made came out awesome with the store bought fondant - clean & neat... so before I undertake the Angry Birds project for my sister I wanted to get your opinion on the comparison between the two.

    I have found the store bought and the home made to be fairly equal in workability. Your finished product if done right should be perfect for detailed work. If you find it too soft for what you are doing, let it rest in the refrigerator for a bit and firm up. And of course if it is too firm you can nuke it for a couple seconds at a time until you find the desired malleability. It's pretty versatile and forgiving, have fun!

    I want to thank you for your information & encouragement. I made the angry birds cake and i was AMAZED at how realistic they came out! I couldn't believe I had made them myself! my Brother in Law to be LOVED them and that was the highlight for me.

    Thank you for the encouragement, but I haven't done them yet - i'm still chicken.
    I am in CT and with all the rain and humidity we have been having i'm worried they will ooze, sweat, wilt or become sticky. Any suggestions? I don't have a cool dry place per se to keep them. I also noticed a recipe just like yours but without the shortening - what do you believe the shortening adds to this recipe in your opinion? I am wondering if perhaps it helps keep it's integrity ?

    I am making angry birds figures to put on top of a cake for Friday afternoon. I will make the cake and transport it the 1 hr drive and had wanted to place the birds and pigs on the cake once it reaches its destination. I thought perhaps i could transport them in a tupperware type container maybe with wax paper squares to keep them apart ? Any advice would be appreciated. Thanks again!!

    how do you paint the fondant? is the food coloring diluted and what type of brush do you use? do you use a basting brush?

    I was afraid of making my own fondant. This looks totally do-able. Thank you for taking away my fear.
