Slice and bake cookies are exactly what they sound like. It’s cookie dough that you roll out into a log that can then be sliced and baked. No need for a cookie scoop, cookie-cutter, etc. Like with these chocolate pinwheel cookies, you can keep the cookie dough log in the fridge or freezer (often referred to as icebox cookies) and simply slice off as many cookies as you want to bake in one go. Then return it to the fridge - easy peasy!
