In a skillet over medium-high heat, sear pork chops for 2-3 minutes on each side, just until slightly browned.
Transfer pork chops to a baking dish (make sure they're touching and not too spread out).
In a small bowl, whisk together maple syrup, water, minced onions, vinegar, Worcestershire sauce, chili powder, and salt and pepper. Pour over pork chops.
Bake for 35-40 minutes, or until cooked through.
Notes
The secret to these pork chops is to sear them before they bake. That way, it keeps them from drying out. Nobody likes a dried out pork chop for dinner. The second secret is the sauce that it bakes in. If you use a smaller pan (so that the pork chops are touching and not spread out so much), they will bake in the sauce keeping them nice and moist (again - no one likes a dried out pork chop for dinner).
