Transfer the butter mixture to the center of a piece of plastic wrap and spread the butter into a log shape. Lift one side of the plastic wrap and cover the cowboy butter. Gently squeeze to form a log. Roll the log to completely seal the cowboy butter. Twist the ends until very tight to compact the butter into a tight log. Refrigerate until firm, about 2-3 hours.

Notes:
- Any type of butter works well here, but try and source the best quality butter for the best-tasting cowboy butter.
- We recommend making the cowboy butter a day in advance for a more flavorful cowboy butter. The extra time gives the flavors to meld.
