For a richer flavor, use brown butter in place of regular softened butter. Brown the butter in a saucepan over medium heat until it has a nutty aroma and golden-brown color, then let it cool and solidify before using. If the dough becomes too soft while rolling, return it to the refrigerator for a few minutes to firm up. Store baked cookies in an airtight container at room temperature for up to 5 days. Feel free to experiment with different extracts, such as vanilla, almond, or peppermint, to customize the flavor of your cookies.
