1 box Betty Crocker traditional brownie mix 9"x13" size
1/3 cup oil
1/4 cup water
3 giant Symphony candy bars
Make the Brownies according to the box with two exceptions...add a third egg and reduce the 1/2 cup oil to 1/3 cup.
Pour half the batter into a greased 9 x 13" pan and arrange the candy bars over the top--covering as much of the batter as possible. Cover with remaining batter and bake according to the box instructions.
Cool and cut. Serve slightly warm and whenever possible, with a tall glass of milk!
Leftovers may need to be softened slightly in the microwave, as the chocolate does solidify over time.
