-true, these aren't a replacement for actual home made cookies. however, if you don't have the time to bake some of your own and yet don't want to suffer through a crunchy crumbly version of a cookie that is more delicious when it is soft, then perhaps this is a viable option for you.
Step 1: Boil Water
Step 2: Make a Steam Bath
Step 3: Add Cookies
i have not tried this process on cookies that are inherently crunchy, like oreos or ginger snaps, so i can't recommend it. i tested this with some pepperidge farm, nantucket cookies and had good results.
Step 4: Cover & Wait
i waited somewhere between three and five minutes. sorry i don't have an exact time, but i would bet that the time would vary depending on the density of the cookie.
Step 5: Check, Remove & Enjoy
remove them carefully from the steamer. (they may be prone to breaking)
