Mix the all-purpose spice and oil together in a small bowl. In a dish, brush the mixture over the chicken liberally using all of the oil. Cover the meat with plastic wrap to marinated.

Heat a skillet over medium flame until smoky and hot. Place the chicken into the pan without overcrowding. Allow the meat to cook for 7-8 minutes before flipping. They should release easily at this point. Cook on the other side for about 2-3 minutes.

Add the butter and turn the breasts to coat. Turn off the heat and remove the chicken to a plate to rest for 5 minutes before serving.
