Add me to those who put the fondant on the cookies when they're hot from the oven. Sometimes I use a dab of RI or water to adhere accents.
I love the taste of MMF on cookies, especially when it's flavored (the most popular one thus far has been cheesecake flavoring from Bickford Flavors, but I have more to try.

) I also use a not-so-sweet cookie recipe.
I don't much like MMF otherwise.

I have a bucket of Satin Ice I keep intending to try, but I keep wanting to see how certain flavors work with MMF and just haven't used it yet.
