Preheat oven to 400 degrees. Rub lamb chops with one of the garlic halves, then brush the chops lightly with oil and season with salt and pepper. Heat a large nonstick skillet over high heat. Add the lamb chops and brown well on both sides, about 2 minutes per side. Transfer the chops to a small ovenproof dish and roast until desired doneness, about 10 minutes for medium-rare. Meanwhile, pour beef broth and 1 cup of beer into the skillet; stir in molasses and the remaining garlic. Bring to a boil and cook over medium-high heat until the liquid is reduced by half, about 8 to 10 minutes. Remove garlic and stir in mustard. In a small bowl, combine cornstarch and remaining beer. Add to the sauce in the pan and whisk until slightly thickened. Season to taste with salt and pepper. Serve Immediately.
