I found this scoop & release cookie dropper the other day and immediately balked. While it might seem like a genius idea, I've got a great tip that works just as well. Instead of investing $9 on a cookie dropper, why not spend the same amount on an ice cream scooper instead? I use mine every time I make cookies. It's a great way to come up with uniform drops for even baking, and the perfectly round scoop creates perfectly round cookies, making your cookies look like they came from a professional bakery! Just remember, that a larger scoop size will create a larger cookie, meaning longer baking time. And conversely a smaller scoop will create smaller cookies, meaning a shorter baking time.
