1 1/4 cups packed brown sugar
1/2 cup butter, softened
1 egg
1 1/4 cups all-purpose flour
1/4 tsp. baking soda
1/8 tsp. salt
1 cup miniature semisweet chocolate chips
Chocolate Frosting, (recipe follows)

2 ounces unsweetened baking chocolate
2 TBSP. butter or margarine
2 cups powdered sugar
3 TBSP. hot water

Heat oven to 350 degrees. Lightly grease cookie sheet. Beat brown sugar, butter and egg in large bowl with electric mixer on medium speed, or mix with spoon. Stir in flour, baking soda and salt. Stir in chocolate chips. Drop dough by level teaspoonfuls about 2 inches apart onto cookie sheet (dough will flatten and spread). Bake 8 to 10 minutes or until golden brown. Cool 1 to 2 minutes; remove from cookie sheet to wire rack. Cool completely. Spread 1 tsp. Chocolate Frosting between bottoms of pairs of cookies.

Melt chocolate and butter in 2-quart saucepan over low heat, stirring occasionally; remove from heat. Stir in powdered sugar and hot water until smooth and spreadable. (If frosting is too thick, add more water. If frosting is too thin, add more powdered sugar.)
