Rhonda's Ultimate MMF

I love to work w/ fondant. My past expereinces w/ mmf was that it always tasted too sweet. I've played around with several concoctions and variations and I think I've found the ultimate taste. It is pliable, easy to use and DELICIOUS. Try it for your self and let me know what you think!

Rhonda's Ultimate MMF


  • 15 oz. mini marshmallows 2 T water 1/2 tsp salt 2 tsp lemon juice (fresh or bottled) 2 tsp light corn syrup (helps w/ pliability) 1 tsp vanilla 1/2 tsp lemon extract 2 lbs (approx 7 C) confectioner's sugar, sifted 1/2 C Crisco or vegetable shortening


  1. Grease microwave proof bowl w/ Crisco. Also grease wooden or heat proof spoon. Pour marshmallows and water into bowl. Microwave for approximately 2 minutes stopping and stirring at 40 second intervals. Mixture should be soupy.
  2. Take out of microwave and immediately add corn syrup, lemon juice, salt and extracts. Stir well. Sift confectioner's sugar into mixture, one cup at a time. After approximately 5 cups, grease your hands well with Crisco and knead the mixture in the bowl. Add the sixth cup and continue to knead. Now grease your work surface well and turn mixture out of bowl onto counter. Sift remaining sugar, regrease hands, and knead well. If mixture seems soft, add one additional cup of powdered sugar.
  3. Shape into a mound and put a coating of crisco on outside. Double wrap in cling wrap and insert into ziplock bag. Press air out of bag and seal. Allow to rest overnight, but, can be used after sitting for a few hours.
  4. **Quick note, if you can order the Princess Cake and Cookie emulsion it will be well worth it. It gives this fondant a delicious flavor and I have been able to convince brides who hated fondant to order fondant wedding cakes after sampling my fondant. Hope you like it!

I tried making marshmallow fondant, and it tasted way to sweet to me, although it was easy to work with. Thanks for sharing your recipe. I'm so excited to try this!
really like this - and I have made a ton of cakes with the original MMF recipe - but the lemon is such a nice twist ... still need to roll it out - but for taste I give it a 10 - I'll be back with a verdict when I have covered my cake in a couple of hours (didn't realize it had to rest - shame on me for not reading through the whole recipe!)
LOVE this recipe. Use it all the time. I like it better than Satin Ice, Wilton, and some others. I find it very easy and inexpensive to make. The flavor can easily be adjusted and the consistency is great. Thanks Rhonda!
What is princess cake and cookie emulsion? When do you add it to recipe? Where do you suggest to buy this? Thanks, I will try this fondant.
I actually saw the princess cake and cookie emulsion at my Hobby Lobby, I think it is a new item since I've never seen it there before. I also would like to know when to add it to the recipe and do I omit other ingredients if I use the Princess cake and cookie emulsion? I love this MMF recipe and would love to try it using Princess too. Thanks, Lisa
Thank you, Rhonda. I used your recipe this last weekend, and it was delicious!
Thank you so much I have to try it, I do work with regular mmf and I add some corn syrup but now I will try this recipe
has anyone made this recipe using regular-sized marshmallows?
Rosie, I've used regular marshmallows instead of miniature in regular MMF, so I have to imagine that they work work all right for this as well. Just be sure to use fewer regular mm than it calls for mini.
Has anyone ever tried this with fresh orange juice and orange extract instead of the lemon flavors? I love to use fresh orange buttercream on white cakes, perhaps my favorite flavor combination; and would love to try this fondant recipe but am a little nervous about the lemon/orange combo.
I can not say Thank you enough! I am still new to decorating and I have not wanted to try MMF until now. I tried another recipe and it was awful. I keep reading everyone’s comments and I thought 10 stars is saying something. If you are scared to try MMF, you HAVE to try this. I truly enjoyed making it. It taste so good and it is not dry. I have found that Crisco is a key in helping knead. I didn't use the lemon ext. (didn't have any) just added a little more lemon juice. I also made this stove top and added the liquids as the MM melted. It is a messy process, but if you make enough to keep on hand it is worth it! Thank you Rhonda and everyone for your comments...I hope to post a pict. soon! Today was a good day in my kitchen! :)
I tried this recipe for the first time today, and it is very good! I love the look of fondant, but hate the taste of the stuff you buy so I have always made MMF. I always found the MMF incredibly sweet. This fondant is so much better, and very easy to work with! I did try it today with orange extract added instead of the lemon (per my question above) and it was awesome! Two thumb's up!
love it love it love it !!!!! Sooo much easier to work with and tastes great !
I love this recipe! I am not a lover of fondant, but this recipe is the best I've tasted and worked with. Just wondering if anyone knows an approximate yield for this recipe?
A few questions: 1. How do you store the unused MMF, how long does it keep? 2.I am making leaves out of it, how far in advance can I make them? 3.Could you use marshmallow fluff? (Gelatin in marshmallows a no-no for some) Thanks!
This recipe is fantastic! My hubby hated fondant until he tried this - then I had to "shoo" him away so I'd have enough to finish my project. Thank you! (And I LOVE that Princess emulsion, too - I call it my not-so-secret ingredient in just about all my icings) Cheers!
This recipe is wonderful and very easy to make. Thank you for sharing!!!
what is princess emulsion and how do you add it to the recipe?
How long does this keep stored in plastic zip lock bags?
This is definitely the best MMF I have worked with. It was more pliable than normal MMF and tasted great! I added 1 tsp creme bouquet and 1/2 tsp vanilla and the stuff was soooo good! I will definitely use the recipe from now on. The only downside was that I couldn't get it to harden with tylose powder, so I will not be using it to make bows.
