Eileen's Tips for Success
- Don’t skip the parchment paper! It makes cleanup a breeze and keeps the cookies from sticking to the baking sheet! A baking mat would also work.
- Once you add the dry ingredients to the dough, mix until just combined. Overmixing can lead to tough cookies.
- If you don't have a cookie scoop, you can weigh the dough balls or even use an ice cream scoop to get perfectly sized cookies.
