I am in a bind as I am making cookies for a b-day party and one of the little guests is severely allergic to eggs, nuts, etc. Mom says she can have a purchased Rice Krispie treat and would I please put it in a cute bag like the other cookies? Oh, so sad. My thought it to at least make the Rice Krispie treat from scratch, cut it in a large flower shape and cover with MMF, but I have never used/made MMF. Does anyone have a specific recipe they recommend? Will it adhere to the Rice Krispie treat if the treat is warm? I think MMF has to go on a warm surface to adhere. I can't use RI for any kind of glue due to the egg allergy issue and my Wilton meringue powder has egg white.

No time for trail and error as I need to do it tomorrow, so a recipe recommendation would be much appreciated! Thanks, ladies!

MMF would be perfect for what you are doing, the recipe I use is Rhonda's Ultimate Marshmallow fondant
You can color it, shape it, and you can attach it warm or cold...just use a tiny bit of corn syrup to attach.
There are some really great things you can do with rice crispy treats, so have fun...everyone will be jealous of her yummy treat!

I second wyckedwytch 's recommendation of Rhonda's Ultimate MMF. It is just great.

Thankyou wyckedwytch and linedancer! That is what I needed! As I only need a small amount (for two treats) have you ever decreased the recipe size?
Thanks again for your help!

I have made half many times. It still makes quite a bit. It keeps well if you double wrap it in plastic wrap and put it in a ziplock bag. It is really fun to work with, you might want to try it for some of your other cookies.
It is my preferred icing.
