We will get the obvious one out of the way. Use a cookie scoop for your cookies! If you are using a spoon to scoop your cookie dough, or rolling the dough balls by hand, you my friend, have a lot more patience than I do. Besides being A LOT faster, using a cookie scoop to dish out your cookie dough will ensure even baking, consistent bake time, uniform cookies, and clean hands!
If you have ever tried making homemade meatballs, you know how hard it is to try to make all the meatballs the same size. Unless you have a cookie scoop! No more eye-balling your meat-balls. With a cookie scoop, none of your meat balls will be under-baked because it's bigger than the rest of them.
