1. Preheat oven to 350°. Prepare brownie batter according to package directions for cake-like brownies. Pour into a lightly greased 13- x 9-inch pan. Sprinkle batter with frozen cherries.
2. Bake at 350° for 27 to 30 minutes or until a wooden pick inserted in center comes out with a few moist crumbs. Cool completely in pan on a wire rack (about 45 minutes). Spread frosting over cooled brownies. Spoon preserves over frosting; gently swirl with a long wooden skewer or knife. Cut into squares.
