Place the steaks indirectly on the grill and smoke them at 225°F for 30 minutes. I used my Nomad Grill which works great for smaller cooks like this.

In a food processor, combine all ingredients and pulsate it until all of the ingredients are thoroughly combined. It should be the consistency of a very soft paste.

Remove the mixed butter from the food processor and place it on some plastic wrap. Tightly secure the butter and roll it into the shape of a stick of butter then place in the fridge for 15 minutes.

Increase the heat on the grill to direct cooking then sear the steaks flipping every 2 minutes until they reach your desired doneness.
