For a crispier cookie, bake a little longer; for a softer center, reduce the baking time slightly. Make sure the butter is fully softened so it creams well with the sugar for the best texture. Rolling the dough in cinnamon sugar adds extra flavor and a light crunch on the outside. You can chill the dough for 20–30 minutes if you prefer thicker cookies that spread less. Let the cookies cool on the baking sheet first so they can set properly before moving them.
