Yes, you can! I find it best to freeze these pumpkin cookies without the frosting though. Just for the best taste, texture, and freshness of everything. Freeze pumpkin cookies WITHOUT the frosting - make the cookies, and cool them completely. Set each cooking on a baking sheet making sure not to touch each other. Place in the freezer for 30-60 minutes or until frozen. Place frozen cookies in a freezer-safe and ait tight container or bag. Keep in the freezer for up to 6 months. To thaw, remove it from the freezer and place it in the fridge for 24 hours. Frost as normal.
