This is a different version of the cookbook - since I found it on pg 310 of my Better Homes and Gardens New Cookbook (paperback, 1985) - but maybe this is the recipe you're looking for:
Double Chocolate Drops
1-1/2 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 cup shortening
2 squares (2 ounces) unsweetened chocolate
1 cup packed brown sugar
1 egg
1/2 cup buttermilk or sour milk
1 teaspoon vanill
1 6-ounce package (1 cup) semisweet chocolate pieces
1/2 cup chopped walnuts
Mocha frosting
Grease a cookie sheet. Stir together flour, baking powder, soda, and 1/4 teaspoon salt. Melt shortening and unsweetened chocolate over low heat. Cool 10 minutes. Stir in brown sugar, egg, buttermilk or sour milk, and vanilla; mix till smooth. Stir dry ingredients into saucepan mixture; mix well. Stir in chocolate pieces and nuts. Drop from a teaspoon 2 inches apart onto a greased cookie sheet. Bake in a 350 degree oven about 10 minutes. Cool about 1 minute before removing to a wire rack. Frost with Mocha Frosting. Makes about 42
