This is a recipe for Starbucks-style large chocolate chunk cookies made with rice flour. Because it uses melted butter, the dough is easy to prepare by simply mixing it with the dry ingredients. Chill the dough in the refrigerator, shape it into 10cm circles, and bake in a preheated oven for 12 minutes. You'll enjoy a satisfying cookie with a crispy exterior and a moist interior, packed with plenty of chocolate. Tips for shaping and baking in the summer are also included.
