Chocolate Marshmallow Cookies

My mom thrills me when she makes these.

Chocolate and marshmallow -- a favorite combination!

1/2 c butter

1 c sugar

1 egg

1 t vanilla

1 3/4 c flour

1/2 t salt

1/2 c cocoa

1/4 c milk

18 large marshmallows, cut in half horizontally (with clean scissors)

Frosting:

1 egg

1/3 c butter, melted

1 1/2 oz unsweetened chocolate, melted

1 t vanilla

1 1/2 c powdered sugar

pecan halves

Cream butter and sugar. Add egg and vanilla, beat until creamy. Add dry ingredients alternately with milk. Drop by a teaspoon onto greased cookie sheets. Bake at 350 for 8 minutes. Placd 1/2 marshmallow, cut side down on each cookie. Bake an additional 2 minutes. Top each cookie with icing and a pecan half. (Sometimes it's easier to dip the cookie, marshmallow side down, into the icing because it's runny.)
