Preheat the oven to 350 degrees F. Grease a 9-x-13-inch glass baking dish and set aside.
In a medium bowl, combine brown sugar, butter, eggs and vanilla. Mix well with a wooden spoon.
Gradually add flour, salt, baking powder and baking soda.
Stir until well combined and pour into the prepared baking dish.
Sprinkle with chocolate chips and bake for 24–28 minutes.
Let cool completely in the pan before cutting. ENJOY
