Add the salt, chili powder, onion powder, garlic powder, and paprika to a small bowl and stir to combine.

Sprinkle half of the spice mixture over both sides of the chicken breasts to season. Reserve remaining seasoning.

Heat 2 tablespoons butter in a large skillet over medium heat until melted.

Add the chicken breasts and cook for about 5 minutes per side or until cooked through.

Remove chicken to a plate and set aside.

Add the heavy cream, remaining 2 tablespoons of butter, and reserved spice mix to the skillet. Whisk well to combine.

Bring to a boil and let sauce thicken slightly, stirring often, about 2 minutes.

Return chicken to the pan to coat with the sauce.

Serve immediately.
