Combine all ingredients and mix until butter is whipped, place in plastic wrap and roll into log. Set in fridge until the whipped butter sets up.
Preheat skillet over medium-high heat. Pat whole tenderloin dry and rub the spice mixture over all sides of the loin, coating evenly. Shake off excess, coat the pan with EVOO and sear on all sides for approximately 2 minutes or until a good sear is achieved. Place loin in a preheated oven at 400 degrees F for approximately 15 minutes or until desired temperature is achieved being careful not to overcook (Elk is lean and will overcook quickly). Let meat rest for a few minutes before serving.
Slice the loin into 3/4" pieces and serve place prepared butter on top, and enjoy.
