To make the bourbon sugar, combine sugar, bourbon and vanilla bean in a mason jar. Shake well to combine, occasionally removing the lid to stir to make sure all of the sugar is coated. Seal and let sit for 24 hours.
Remove vanilla bean from sugar before use.
To make the spicy bourbon sugar rub, combine bourbon sugar, salt, paprika, pepper, cayenne, cumin and garlic powder in a small bowl. Whisk to combine.
Remove steaks from packaging and pat dry with paper towels. Coat both steaks in the spicy bourbon sugar rub on all sides.
Heat canola oil in a cast iron skillet over medium-high heat. Once hot, add both steaks. Sear on all sides until browned, approximately 1-2 minutes per side.
Cook until it reaches your desired temperature (approx. 5-6 minutes for medium rare).
Remove from the cast iron skillet. Rest for 10-15 minutes before slicing and serving.
Serve with roasted asparagus and crispy steak fries.
