Parchment paper (a tip)
Just a quick tip... when baking cookies (recipes to follow soon!), use parchment paper on top of your cookie sheets. When you take them out of the oven you can just (carefully!) slide the parchment paper, cookies and all, right onto your counter (or cooling rack) to cool. And if you prepare your next batch while the current one is baking, you can just slide the ready-to-bake cookies right on to the hot cookie sheet and bake.
It's easier to slide them on to another (cooled) cookie sheet, but in a pinch, a hot one will do. Oh, and fold or cut the parchment paper to fit your cookie sheet. Any overhanging paper will burn. Can be used for baking so long as the temperature doesn't exceed 450°F.
