This is my new favorite baking tool. The cookie scoop. I've been eyeing them for years and finally I drove my butt down to South Portland to Wililams Sonoma and bought two. One medium sized and one larger. These have simplified my life so much. The larger scoop fills a cupcake liner perfectly. The smaller one makes perfect sized whoopie pie cakes. No more mismatched sizes! I've also used both sizes for cookies, like chocolate chip.
I don't know how I survived without one of these!!
