Combine butter, vanilla, sugars, flour and salt in a large mixing bowl. Press 1-1/4 cups of mixture into the bottom of a lightly greased 13"x9" baking pan. Set remaining crumbs aside. Bake at 350 degrees for 10 minutes; remove from oven. Combine one cup chocolate chips with condensed milk in a small saucepan; melt over low heat until smooth. Spread over crust. Sprinkle reserved crumbs over chocolate mixture. Drop jam by teaspoonfuls over crumbs; sprinkle remaining chocolate chips on top of jam. Bake at 350 degrees for an additional 30 minutes. Remove to a wire rack; let cool one hour. Cut into bars. Makes about 2 dozen.
