Frosted Peanut Butter Fingers Recipe

In a large bowl, cream butter and sugars until light and fluffy. Beat in 1 cup peanut butter, egg and vanilla. Combine oats, flour, baking soda and salt; gradually add to creamed mixture, beating well after each addition. Spread into a greased 15-in. x 10-in. x 1-in. baking pan. Bake at 350° for 13-17 minutes or until golden brown. Cool slightly on a wire rack, about 12 minutes. Spread with remaining peanut butter. Cool completely. In a large bowl, beat the butter, confectioners' sugar, cocoa, vanilla and enough milk to achieve spreading consistency. Spread over peanut butter. Cut into bars. Yield: about 3 dozen.
