After doing some Googling, I found this very simple coconut macaroon recipe on AllRecipes.com. I followed the recipe exactly, and took some of the advice I found in the comments section: let the dough sit in the frige a bit so the cookies are easier to shape. I'm not sure what it's like if you don't chill the dough, but it was easy enough--although a bit messy--to make them into balls for baking.
I doubled the recipe so that I could maximize the amount of cookies I could bring to the bake sale!
These were really easy and really good.
