We're doing cookie decorating for P's party and I am at a total loss at what the best "cookie" recipe/prep to use is. The cookies will be in the shape of a "P" so it needs to be something I can roll out.

Should I make the dough myself, what is the best recipe?
Is there a "cookie in a box" mix that is good?
Or maybe in the refrigerated section?

IDK! Any bees cookie makers?
