Can I use instant oats instead of quick cooking or rolled oats?

How long will these cookies stay fresh?

Store in an airtight container at room temperature for up to one week, or freeze for up to 3 months.

Can I freeze the cookie dough?

Yes, shape the dough into balls and freeze on a baking sheet, then transfer to bags. Bake directly from frozen, adding 1-2 minutes to baking time.
