To prepare a special chocolate chip sandwiches cookies recipe, you'll first need to prepare your ingredients. First, preheat your oven to 350?F (177?C) and grease two 9-inch square baking pans with non-stick cooking spray. Then, add your dry ingredients to the wet ingredients and stir to combine. Add your chocolate chips and mix until they're evenly coated. Bake the cookies for 10 to 12 minutes or until the edges are lightly browned. Remove from the oven and allow to cool for 5 minutes before cutting into squares.
