Prepare the Pork Chops: Pat the pork chops dry with paper towels. In a small bowl, mix together the garlic powder, onion powder, smoked paprika, black pepper, salt, and brown sugar. Rub this spice mixture evenly over both sides of each pork chop. Sear the Pork Chops: Heat olive oil in a large skillet over medium-high heat. Once hot, add the pork chops and sear for 3-4 minutes on each side until they develop a golden-brown crust. Ensure the internal temperature reaches 145°F (63°C). Remove the pork chops from the skillet and let them rest. Prepare the Peppercorn Sauce: In the same skillet, reduce the heat to medium and add the butter. Once melted, add the green peppercorns and cook for about 1 minute. Carefully add the brandy or cognac (if using) and cook until mostly evaporated. Pour in the beef broth and heavy cream, stirring to combine. Let the sauce simmer for 2-3 minutes until slightly thickened. Season with salt to taste. Serve: Spoon the peppercorn sauce over the rested pork chops and serve immediately.
