Bake at 350 degrees F (175 degrees C) for 8 minutes.
Sprinkle the chocolate chips evenly over the partially cooked brownies. Pour the melted caramel mixture over the top and with a teaspoon drop the remaining 1/2 of the batter evenly over the top.
Bake at 350 degrees F (175 degrees C) for 20 minutes. Let brownies cool in pan then cut into bars.
