1 3/4 c. sifted flour
1 tsp. baking soda
1/2 tsp. salt
1/2 c. cocoa
1/2 c. butter
1/2 c. sugar
1/2 c. milk
1 egg
1/2 c. chopped nuts (optional)
1/2 tsp. vanilla

Sift dry ingredients. Cream butter and sugar; add eggs, milk and vanilla. Mix well. Add dry ingredients and nuts. Drop by teaspoon on greased cookie sheet. Bake at 350 degrees for 8 minutes (no more). Cut marshmallow sin half (tiny ones do not work as well). Be sure they are fresh and soft.

Remove cookies from oven and place 1/2 marshmallow on top of each cookie, giving a slight push to break the top crust slightly. Return to oven for not more than 1 minute. Remove and cool. Ice each cookie with a chocolate butter icing.
