How Do You Make Cookies Crunchy?
To make cookies crunchy, use less butter or oil and more sugar and flour in the recipe. This will result in a drier dough, which will produce a crisper texture when baking. Also, avoid adding too much liquid ingredients like milk or water. Bake the cookies for longer than the recipe calls for and let them cool completely on a wire rack before storing them in an airtight container. This will help retain their crunchiness.
