3 ounces unsweetened chocolate 1 cup butter 1 cup granulated sugar 1 large egg 1 teaspoon vanilla extract 2 cups all-purpose flour 1 teaspoon baking soda 1/4 teaspoon salt additional sugar
Microwave chocolate and margarine in large microwavable bowl on high 2 minutes or until margarine is melted. Stir until chocolate is completely melted. Stir 1 cup sugar into melted chocolate mixture until well blended. Stir in egg and vanilla until completely blended. Mix in flour, baking soda and salt. Refrigerate 30 minutes. Heat oven to 375 F. Shape dough into 1" balls; roll in additional sugar.
Alternately, roll out to 1/4" thick and cut with cookie cutters. Place, 2" apart, on ungreased cookie sheets. (If flatter, crisper cookies are desired, flatten balls with bottom of drinking glass.) Bake 8-10 minutes or until set. Remove from cookie sheets to cool on wire racks. Decorate with icing and sprinkles, if desired.
