Recipe Help Please: Thin Mint Memory of over 30 Years Ago!

[4MyDisney]

I often made a desert using Girl Scout Thin Mint Cookies. It has made me almost crazy trying to find this recipe to make these for the last several years, I hope you all can help. You made this in a muffin pan, by first putting in a cupcake paper, then a cookie. Then I made a white creme or batter type mix, I remember putting peppermint flavoring in it and I actually think it was made out cool whip?? You pour that on top of cookie. Put that in the freezer like an hour, then put a half cherry on top and chopped nuts if desired. You kept these frozen, pull out and eat. Did not need to thaw, it was soft, like butter.
