In a small saucepan, boil the orange juice until reduced to 1/2 c (keep an eye on it or it may boil over). Add the reduced juice to the butter in a large mixing bowl and combine. Mix in the remaining ingredients in the order given. Pour batter into a 8x11-inch pan sprayed with cooking spray. Bake 350°F for 30-40 minutes or until desired doneness. Yield: 24 brownies.
