Depending on the size of your cookies you may need to let them bake longer or instantly remove from baking sheet once out of oven so they won't continue to bake.
I made my cookies a little bigger and baked them about 12-14 minutes. I allowed them to sit on the baking sheet for a minute and then placed on cooling rack.
If your cookies are about a tablespoon and a half in size then 8-10 minutes should be enough time to bake.
