Preheat oven to 350°F. In a medium bowl mix the Nu Life Market’s Gluten Free All-Purpose Flour, salt, and baking soda; set aside. In a separate bowl use a hand held mixer or a stand mixer to cream together the butter, brown sugar, and white sugar. Using a rubber spatula scrape the sides of the bowl. Beat in the vanilla and eggs until well mixed. Slowly add the flour mixture into the butter mixture. Fold in the chocolate chips. Spread in a greased 9×13″ baking dish or a greased cast-iron skillet. Bake for 15-18 minutes or until golden brown.
