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

wats it taste like?
Penolopy Bulnick (author)  Newell_Jalynn3 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!

I do not think it dries hard. I usually don't leave it out long enough to tell.

You could use paste food color for more vibrant colors

Neat, Fondant is such a cool "building" material. Can't wait to see what you make with it. I love the pastel colors. Thanks for posting.

I will have to give that a try. I was using food coloring with my fondant and flavoring my rice krispie treats with powdered drink mix now to make my watermelons. It would nice to pair it with another flavor.
Penolopy Bulnick (author)  bwente6 months ago
Oooh drink mix! How did it work out? Sounds so genius, I don't know why I didn't think of it!
Turned out pretty good. I used packet (enough for two quarts of drink) the rice krispie treats are plenty sweet. Plus, I didn't have to use as much food coloring. The first time I made them I used strawberry marshmallows , this time I could not find any.

I didn't add any to the fondant, I wasn't sure if it would dissolve enough without heat and be gritty. Next time I will try or might grind the kool-aid in my mortar. They have a watermelon flavor that I will use for the inside, and a kiwi lime for the outside. Should be a good flavor combo.
what type of powdered drink mix did you use? traditional add your own sugar or the one bottle of water at a time no sugar ones? and how much? thanks!

I guess it is okay to mention brand names. It was Kool-aid, watermelon flavored, they has the most flavors.
how could you make the colors more vibrant
I would imagine that food coloring would do the trick. When I was 'into' cake decorating I used Wilton's paste food colorings, it doesn't add unneeded liquid...and the colors are quite vibrant.

How can you make the colors more vibrant?
Penolopy Bulnick (author)  disneylover6 months ago
You could try adding more jell-o mix, but I'm not sure if that would do it, especially with the yellow. You might have to add in a bit of food coloring too. You can see with the blue when I added just a little water, the color still isn't much brighter than the final product.
