Stir everything but the steaks, butter and broth in a pot over medium heat, stir until sugar is melted.

Place steaks in shallow dish, pour marinade over steaks and cover with airtight lid. Refrigerate, at least 4 hours, up to overnight. Overnight is best.

Heat iron skillet, melt 2 Tbsp butter. Place steak in skillet and sear both sides, flipping back and forth. Use a meat thermometer to check for your desired temperature: medium rare 145*, medium 160*, well done 170*.

Remove steaks to serving plate. Pour 1 cup broth into skillet, use edge of wooden spatula to scrape bottom of skillet to remove steak bits. Spoon over steak(s) just before serving.

Enjoy!
