I need to make about 100 cookies for a cookie decorating party for children. I don't have the time to make all the cookies at once so I wanted to stretch it out. Can I freeze them? If so can someone recommend a recipe? And also how do I thaw them? Also they don't want royal icing so do you think buttercream will work? Sorry so many questions! TFL!

Yes-
I have a book that recommends it undecorated
I put them in saran and then put styrofoam between the layers of cookies. I thawed them in the wrap room temp--they did fine (in our dry climate)
I didn't decorate them until I needed them--I used fondant (vs. RI)

No Fail Sugar Cookies in the recipe section under cookies are great! And Toba's Glace also in the recipe section under icing is really good.

sure can... here are some threads that talk about freezing cookies, both undecorated and decorated.
