Prepare the brine by combining salt and sugar in water until dissolved. Submerge the beef chops in this mixture and refrigerate for 30 minutes to 2 hours.
Remove beef chops from the brine and pat them dry with paper towels. Season both sides with salt and black pepper.
In a small saucepan over medium heat, combine maple syrup, Dijon mustard, apple cider vinegar, and garlic powder. Simmer until reduced by about one-third, about 5-7 minutes.
Heat a large cast-iron skillet over medium-high heat and add vegetable oil. Sear the beef chops for 3-4 minutes on each side until golden-brown.
Reduce heat to medium-low, brush each chop with glaze, and continue cooking for 2-3 minutes per side until internal temperature reaches 145°F (63°C).
Remove the chops from the skillet and let them rest for 5 minutes. Drizzle any remaining glaze over the top before serving.
