These have been a favorite of our family for a LONG TIME. We use the mini muff pans and make the recipe at 4x for the Christmas season.Had always used the mini tin holders in the pan, haven't tried without them yet.Great deal maybe with the extra we save on the holders we can make MORE! We never put them in the fridge or freezer we let them cool naturally. This lets the peanut butter cup melt within the cookie.We also simply refrigerate the Reeses and seems to work just fine.However you choose to make them enjoy!
