1 sm. pkg. Hydrox chocolate cookies
30 reg. size marshmallows
1/2 c. milk
16 oz. Hershey bar 9 (grated)
2 c. Cool Whip

Crush enough of the cookies to cover the bottom of an 8 inch square cake pan. Line the pan with the cookies. Melt the marshmallows in the milk over low heat. Cool this mixture and then fold in the Cool Whip and half of the grated Hershey bar. Pour this mixture over the cookie crumbs. Cover the top with the rest of the grated chocolate. Additional cookie crumbs can be added to the top if you wish.
