Pound each chicken breasts to an even 1/2 inch thickness.
Place milk and bread crumbs in separate, shallow bowls.
In a large skillet, heat butter over medium heat. Dip chicken in milk, then coat with crumbs. Cook chicken in butter, on both sides, until cooked through (About 10 or so minutes). Remove from skillet and keep warm.
Add the garlic to skillet and cook for 30 seconds over medium heat. Add the chicken broth to the skillet. Bring to a boil over medium-high heat, and stir to loosen browned bits from pan. Stir in cream. Boil and stir for 1 minute. Reduce heat.
Add Parmesan cheese, basil and pepper. Stir sauce and cook until heated through. Remember that for a thicker sauce all you have to do is cook it longer. I cooked mine about 5 minutes. Turn off heat and let stand a minute or so and sauce will thicken even more.
