Directions:
Chop 1/4 of the chocolate chips. Sift flour. Blend butter, brown sugar, and 3 teaspoons vanilla. Stir in flour, milk, and chopped chips. Shape in 1/2-inch balls. Place on ungreased cookie sheet, and make a depression in center of each cookie with your thumb. Bake 10 to 12 minutes at 375° F, and then roll in powdered sugar.
In a small bowl over hot water, combine the rest of the chips and the shortening. Stir until melted and then remove from heat. Stir in corn syrup, 2 tablespoons water, and the 2 teaspoons vanilla. Fill each cookie.
Makes about 4 dozen.
