It's always best to reheat our cookies in a preheated oven at 350°F. If you want to feel present ASAP, microwaving at 10 second intervals can do the job, however it won't be as crunchy.
For our 2-ounce cookies, place cookies on a baking sheet and into the oven for 2-4 minutes. For our 5-ounce cookies, leave cookies for 5-7 minutes.
