Combine maple syrup, soy, hoisin, and apple cider vinegar in a small bowl or pyrek with pour spout and whisk with fork. Set aside.
Heat olive oil in large skillet on medium high heat. Turn skillet so it's well oiled. Add chicken, smooth (or what would be skin) side up, to sear.
Cook for 2-3 minutes before adding sauce and then flip chicken, smooth side down.
Keep heat at medium-high and let sauce boil, cooking down. Cook for another 2-3 minutes before flipping to smooth side down.
Keep cooking the glaze and chicken until most of the liquid has cooked off. Keep the chicken smooth side down so that the sauce carmalizes to the chicken.
After another about 10 more minutres of cooking, or until the glaze has mostly cooked off and chicken has reached 165 degrees, remove from heat and serve immediately.
