Yes, you can reheat Insomnia Cookies. Please put them in the oven for 5 minutes at 350 degrees Fahrenheit to make the cookie taste fresh again. Read carefully because this is not as simple as just popping them back in the oven. Reheating cookies helps to soften them up.
You will need a damp paper towel and a microwave. Wrap each cookie individually with a paper towel. It has to be damp and not soaking wet.

Methods
Oven
Insomnia Cookies are better hot right out of the oven. Reheating cookies in the oven makes them too dry to eat. Remove all the cookies you plan to reheat from the recipe. Ensure that your plate has been microwaved oven-safe. Set the oven to 300 degrees, placing cookies over the oven for a few minutes. Allow the cookie to sit for a few minutes.
Use baking soda or warm chocolate sauce. Warm your cookies for four to six minutes. Enjoy the cookies after they are removed from the oven. If you do not have an oven-safe container, you can use a baking sheet for your cookies.
Make sure you put these cookies out well. Let them steep for the balance of sweetness and chewiness. Place a thermometer inside the oven to check that the temperature is accurate–home ovens can be off by 50 degrees or more, making a difference for cookies.

Microwave
As much as cookies are best hot, avoid using the microwave. Microwaves heat by jostling the water molecules around. So if your cookie is already dry, microwaving might not help much other than melting the chocolate chunks, and they have more water content than the surrounding cookie.
If you are desperate, microwave your cookie next to a mug of water. The microwave waves will boil the water, creating a steam cloud inside. That steam will permeate the cookies in the mug. Adding the steamy water vapor back into the dough will make it fresh. You will not be eating molten-hot chocolate chips.
It is handy to put a little water on a paper towel before blotting it off. A sheet of damp paper can be wrapped tightly around your cookies as an alternative. Up to 20 times per second may be enough to microwave cookies. If you take them out and they are not soft enough yet, wrap them in another damp paper towel and microwave again for 10 seconds.
Stovetop
The stovetop method of reheating biscuits involves the use of a pan. The pan’s size depends on the number of biscuits you need to reheat. Place the pan over low heat as you increase the temperature. Get an aluminum foil and place your biscuits inside. Wrap and place the biscuits in the heated pan.
Cover it for heat to be distributed in the pan. The heat should remain low to help preserve the biscuits’ moisture. It takes less than a minute to reheat the biscuits in the pan.
Air fryer
You can reheat cookies in an air fryer by setting them to 300 degrees Fahrenheit for two to three minutes. All the cookies are lined along the bottom to prevent them from getting too crispy or doughy. That softens the cookies while preserving their flavor and texture.
This air fryer sometimes has an app that alerts you when baked goods are ready while connecting to my Alexa or Google Assistant. Put as many cookies as you want on the bottom of the air fryer. The cookies should not touch inside the air fryer. Leave the cookies in the air fryer for 2-3 minutes. Remove the cookies from the air fryer one by one.
The quick heating air inside an air fryer warms up your cookies while preventing them from becoming too crispy. The air in the fryer circulates within a much smaller surface area than the air in an oven. Your old, stale cookies become soft, chewy, and great-tasting treats.5

Microwave
Using a microwave is the fastest way to reheat frozen cookies. It does not take much time and effort to set up, and the procedure is fast and effective. Using the microwave to reheat biscuits gives you fewer chances to spoil the cookies.
Storage
Insomnia cookies can stay fresh for as long as 2 to 3 weeks. That is enough time to have these cookies on any day you feel like eating them. To maximize the shelf life of crisp cookies, place the cookies in a loosely covered container.
Make sure the cookies are cooled before freezing. Place the cookies into an airtight container lined with aluminum foil or plastic food wrap. Wrap the cookies individually in plastic food wrap and freeze them for better results. For baked cookies, also freeze them successfully for up to two months.
Some people choose to refrigerate over freezing. Insomnia Cookies will last in the fridge for up to 7 days. Keep the cookies at room temperature for two to three weeks or two months in the refrigerator. The refrigerator has to be functioning well without power problems. Cookies retain their quality when stored in the freezer for eight to 12 months.
