Pour warm frosting over brownies, spreading evenly. Cool in pan on a wire rack; cut into bars.

After brownies are cool, I put in the refrigerator for about an hour to set. Using a sharp knife dipped in warm water, then wiped dry, cut the brownies. Dip knife in warm water, wipe dry before each new cut.
