Whisk the first five ingredients together in an 8 cup mixing bowl.
Whip the last 3 ingredients together in a separate bowl, and pour over the dry mixture.
Stir with a wooden spoon until well mixed. About 30 stirs will get it. You don't want to over mix.
Spray a 9" x 13" pan. Add the brownie batter, and smooth the top.
Bake at 350° for 20 to 25 minutes.
