In a large bowl, cream together the butter, sugars and peanut butter until smooth. Beat in the eggs, two at a time, then stir in the corn syrup and vanilla extract. Mix in baking soda and oats until well blended. Stir in the chocolate candies and chocolate chips. Roll dough into 2-inch balls and place 3 inches apart on an ungreased cookie sheet.
