Mix all ingredients (except fo the Hershey's syrup) in a large bowl.  Pour 2/3 of batter into a tube (bundt) pan.  Mix Hershey's syrup with remainder of the batter.  Spoon this mixture on top of batter in the pan.  Bake at 350 degrees for 50-60 minutes.  Check for doneness with a knife - the cake may need to be
