Preheat your oven to 350 degrees F.
Combine water, butter, and eggs in a pan and mix thoroughly. (There should be no lumps when you are done.)
Pour half of your batter into a greased 9" x 13" pan.
Cover the brownie batter with your Symphony bars, breaking up the bars as necessary to completely cover the length and width of the pan.
Spread remaining batter atop the Symphony bars.
Bake for 25-27 minutes.
Allow to cool for at least 30 minutes; longer if you want clean squares when slicing.
Slice and serve!
