One of the best time saving gadgets I own is the Pampered Chef Medium Scoop. It was the best $15.50 (price with shipping) I ever spent. It give perfectly sized cookies, which are a commodity around here. My hands also stay clean so I can stop and run after the kids. It is dishwasher safe and easy action. Just dip and dish. I also use for potato pancakes.

Even cooler is the little one they sell is the same size as a mini-muffin cup and the big one is a muffin cup size. I spend forever trying to get them just right.
