Take 1 oz of marshmallows*, add in a little water and microwave that for 1 minute on 50% power. Mix up the marshmallows and make sure they are all melted. I added in coloring here. If you do it now, you get a more thorough color, if you mix later, it can end up streaky. Start mixing in powdered sugar. I slowly add more and more or you get it everywhere. As it starts to stay together, I use powdered sugar to get as much of it off the spoon as possible. You can pour it out onto a clean surface or cling wrap when it stops melting. What I mean is, if you stir it and stop and it looks like it is melting into a pool, it isn't firm enough yet. Transfer to plastic wrap and kneed. I keep a bowl of powdered sugar nearby and keep my hands powdered. I call it good when I can squeeze it and transfer it between hands about 20 times without it sticking to my hand. I've never had it not be sticky. If you are going to use it right away, just set it to the side. If not, wrap tightly in cling wrap and keep in a dry place. It actually keeps for quite a while.

You can make and form the rice krispies or make the marshmallow fondant first. It doesn't really matter. I went fondant then krispies, but I think I should have formed the krispies first. If you do the krispies first, it gives them time to stiffen up and then you'll have very fresh fondant to work with.I decided to talk about what I did to make all my colored MMFs. Here was my method:

Amounts :

1 oz (marshmallows) for red, orange, yellow, and blue

About 10 oz (marshmallows) for green

7 - 10 oz (marshmallows) White (not pictured) and I pinched off just a bit of this to make purple and barely used any.



*The amount of marshmallows you need will depend on how many of that treat you are making. I ended up only having four rainbows and 1oz of each color was too much. So just plan accordingly. Also, for rainbows, you will need more red than orange, more orange than yellow and so on because of the order of the colors. So, going with that, you need very little purple.



What is nice is you can always pop more marshmallows in the microwave and whip up some more MMF. The more you make it, the easier it gets.



**Note from 1st image: I actually made this by mixing 1oz of chocolate marshmallows, 4 oz of black candy melts, along with powdered sugar. It tasted really good (chocolate marshmallows), but it just firmed up too much. Might be just me, or it might be that is just what happens when you mix in candy melts. See here for how I learned this trick, I may try it again another time, it might have not worked so well cause I let it sit and I did such a small amount.
