2 (6 oz.) pkgs. semi-sweet chocolate bits
1 c. evaporated milk
3 c. finely crushed vanilla wafers
2 c. miniature marshmallows
1 c. sifted confectioners' sugar
1 c. flaked coconut
1/2 tsp. instant coffee
1/2 tsp. salt
2 tsp. shortening

Combine bits and milk in top of double boiler. Stir until melted and well blended. Combine all the rest ingredients (except shortening) in a large bowl. (Save 1/4 of chocolate mixture.) Add remaining chocolate to the crumb mixture, mix well, press into well greased 9-inch square pan. Return the chocolate mixture you saved to the top of the double boiler. Add the shortening. Stir until shortening melts.

Spoon this over the mixture and spread evenly. Chill until set. Use some peanut butter in the frosting, if you like. Graham crackers can be used instead of vanilla wafers.
