This recipe is for American chocolate chunk cookies with a chewy texture. Soften the butter, then mix in brown sugar, granulated sugar, baking powder, and beaten egg in that order. Add the cake flour and chocolate chunks to make the dough. Chill the dough, shape it, and bake in a preheated oven at 180°C for about 11 minutes. The process is simple, just mixing the ingredients, making it perfect for beginners. These cookies are moist and soft, and the generous chunks of chocolate make them incredibly satisfying.
