This video shows you how to make addictive chocolate chip cookies using melted butter without fail. Melt unsalted butter in the microwave and let it cool to room temperature. Add brown sugar and egg and mix well until thickened. Sift in cake flour and baking powder, add crushed dark chocolate and white chocolate, and mix lightly until no dry flour remains. Let the dough rest in the refrigerator, then divide it evenly into 8 portions, shape them, and bake in a preheated oven. These cookies have a crispy texture and are packed with chocolate, and are easy enough for beginners to make.
