Jell-O Marshmallow Fondant

Picture of Jell-O Marshmallow Fondant
Marshmallow fondant is already awesome, but if you add jello to it you can make it even more delicious while coloring it at the same time!  Jello seems to mix in really well with the powdered sugar and gives good results for taste and look.

Step 1: Supplies

Picture of Supplies


  • 8 oz Marshmallows
  • 1 lb Powdered Sugar*
  • 3 oz Box of Jello Mix flavor of choice
  • 2 tbs Water (I never measure this but it is about this much)

Helpful Supplies:

  • Silpat Mat (This is the best thing to have when working with marshmallow fondant! So easy to clean it off!)
  • Mixing Bowls
  • Microwave

I made only 2oz at a time and then multiplied it for a whole bag of marshmallows, but if you are wondering, here is what I did for each of the colors shown:

  • 2 oz Marshmallows
  • 1/4 lb Powdered Sugar
  • 4 tsp. Jello Mix
  • Little bit of water

*I actually don't measure powdered sugar. I figure it is always going to take what it takes.

Step 2: Initial Mixing

Picture of Initial Mixing
We are going to start off like normal, but instead of just mixing marshmallows and water, we are going to add in our jello mix.  If the jello has bigger grains, you might want to run it through a food processor.  You want this as fine as powdered sugar so it mixes in well.  Otherwise, it might come out too grainy.

I melt the mix for 50 seconds on half power, take out and stir, melt for 45 seconds on half power, and mix one more time.  If it still isn't melted, throw it in a little longer, but keep an eye on it.  It'll puff up!

This is awesome 'cause sometimes marshmallow fondant is a little bland, you know, so it's nice to give it a little sweetness : )

I'll bet my kids will love this... have to give it a try.
Awesome it looks deliciois

Have you ever tried an instant Jello pudding mix with the marshmallow fondant? I was thinking like banana or chocolate flavor pudding? I like the idea of adding the jello! Also, running the jello through a coffee bean grinder to get it more powdery texture would work great!

Gel or paste food coloring will work the best for making the colors more vibrant. Although, you should wear protective gloves (preferably non-latex to avoid allergic reactions) unless you really love the color you are using as it will also dye your skin.

To get around the Jell-O granuals being too large, try "blooming" it in the water for a minute or two. This would become your first step; adding the marshmallows and microwaving it becomes the next step. Make sure the water is towards the warm/hot side so the Jell-O dissolves.

Blooming is the process of dissolving gelatin in warm/hot water so rubbery "clumps" aren't left behind. Sprinkle it over the surface of the water rather than dumping it all in at once. This will allow all the gelatin to contact with the water and dissolve.

Hope this info is helpful. Great instructions!

Most people I've heard from that hate fondant, like Marshmallow fondant. You of course need to like marshmallows and sugar though :) Hope you enjoy!

I've made marshmallow fondant before and, while it tastes much better and is much more affordable than store-bought fondant, it has a shiny-ness to it that I'm not as fond of. Do you find that this jello recipe fondant has a shine, or is it more matte like store-bought fondant? Thanks! neat idea!

Penolopy Bulnick (author)  Jbszink16 days ago

I haven't noticed the shinyness of the marshmallow fondant really before. It always seems to need to be coated with powdered sugar to stop it from sticking so I feel like that prevents it from being shiny. But I would say that this fondant acts and looks just like normal marshmallow fondant.

Hmmm, I was following a recipe, and that was the result every time. Maybe I wasn't using enough powdered sugar. Thanks!

Yeah, I'm not sure, but I know the more you handle it the shinier it is and also if you try to put it in the fridge and then take it out it will get shiny.

wats it taste like?
Penolopy Bulnick (author)  Newell_Jalynn6 months ago
It will taste like whatever jello you use, but the flavor isn't really strong. You could add more jello for more flavor.

You're welcome :)
The berry blue looked the best too I think!!
I make my own fondant in a very similar way, but never tried adding jello. Sounds yummy and looks great. Home made fondant always taste better I think. I use the food coloring in jars by Wilton. Works great even though the package says not for coloring fondant. :)
Yeah, I haven't found a dye that hasn't worked on marshmallow fondant yet.

Brilliant! Will this fondant dry hard (like traditional fondant or like those little Valentine heart candies)? I want to put it on cookies and then be able to write on them with food markers. Thanks for sharing this, just in time to plan my holiday baking. It's just awesome!
Penolopy Bulnick (author)  deniseto6 months ago
I do not think it dries hard. I usually don't leave it out long enough to tell.
