Directions

1. Prepare and bake brownie mix according to package directions for fudge-like brownies. Cool completely on a wire rack. In a small mixing bowl, cream the butter, confectioners' sugar and vanilla until smooth. Place in a heavy-duty resealable plastic bag; cut a small hole in a corner of bag; set aside.
2. Line a baking sheet with waxed paper. Dust with cocoa; set aside. Cut brownies into 15 rectangles. Using a 1-1/2-in. heart-shaped cookie cutter, cut out a heart from the center of each brownie. Reserve cutout centers for another use. Place brownies on prepared baking sheet. Pipe frosting into centers of brownies.
