3/4 cup butter or margarine, melted
1 can (14 ounces) sweetened condensed milk
2 cups (12 ounces) miniature semisweet chocolate chips, divided
Combine cookie crumbs and butter; pat into the bottom of an ungreased 13x9x2-inch baking pan. Combine milk and 1 cup of chips in a microwave-safe bowl. Cover and microwave on high for 1 minute or until chips are melted; stir until smooth. Pour over crust. Sprinkle with remaining chips. Bake at 350 degrees for 10 to 12 minutes or until chips are melted.
These bars are very rich, so cut them in bite size pieces.
Makes about 4 dozen.
