It's best to make bigger cookies for the right crispy yet chewy texture - I recommend using a tablespoon size scoop for the size of your cookies.
Place 6 scoops of cookie mixture onto one large tray lined with baking paper.
Bake for about 15 minutes.
I like mine to look a little undercooked in the middle, then let them finish cooking on the cookie sheet for a few minutes while they cool.
Then move them to a cookie rack or plate to keep cooling.
If you are freezing these cookies: Form into balls, and freeze on a cookie sheet. After frozen remove and place them in a container to store in the freezer. They will last for about a month in the freezer. To bake just take out and bake as directed, adding a few extra minutes of baking time.
