In a 12-inch skillet over medium heat, melt 1 tablespoon butter.
Sear the chicken breasts for 3-4 minutes on each side, remove from skillet, and set aside. (Note that the chicken won't be fully cooked at this stage.)
Add 1 tablespoon butter, garlic, mushrooms, 1/2 cup wine or broth, and simmer until liquid is almost gone.
Add 1 tablespoon butter, 1/4 cup cream, stir well.
