Preheat oven to 325 F.
In two small bowls, combine ingredients for each layer separately.
Grease an 8"x 4" loaf pan. Spread the chocolate chip cake layer evenly in the bottom of the pan.
Next, spread the brownie batter evenly on top. Top with additional chocolate chips if desired.
Bake for about 20 minutes or until slightly firm in the center. I recommend checking on it after 15 minutes to make sure it is not getting overdone, as all ovens cook differently. Allow to cool before slicing into 8 squares.
