Drop by tsp. full onto an ungreased baking sheet. Bake 8-10 min. at 375 until delicately browned. Frost right away.
Frosting (make while dough cools)
Blend cream cheese, milk, vanilla, and salt. Gradually add sugar until smooth.
If you want both vanilla and chocolate frosting, divide in half.
Melt 1/2 oz. unsweetened chocolate, cool, add to mixture before adding sugar. If all chocolate, add 2 oz. chocolate. This is best.....
For easier frosting, place 2 sq. milk chocolate bar on cookie as soon as out of oven.
