Brown Butter Sugar Cookies
I once regarded sugar cookies as tremendously boring, but these cookies showed me the light. Sugar cookies tend to be a bit crumbly with a very direct sugary flavor (hence the name), but brown butter brings an extra layer of complexity to the flavor along with some much needed chewiness. The full recipe is available over at Sally's Baking Addiction. Sprinkles are listed as "optional" but... you need them. Don't rob yourself of festiveness.
