Combine butter, sugar, egg and vanilla. Beat well. Combine flour and cocoa; add to creamed mixture. Stir in chocolate chips and pecans. Roll into 1 inch balls and place 2 inches apart on ungreased cookie sheets. Using a wooden spoon handle makes a 1/2 inch deep dent in the center of each ball; fill half full of caramel topping. Bake at 350 degrees F for 15-18 minutes or until caramel is bubbly and cookies are set. Cool then remove and drizzle with chocolate coating. These are more like candy than cookies.
