Believe me, with the quantity of chocolate that I've brought back to the U.S., you won't have ANY problems bringing back the "giant" Toblerone. Buy it at the Duty Free store in MUC or, if you have plenty of time, go thru passport control, walk over to the Edeka store in Terminal One and buy it there. You'll have to go thru security and passport control again, but it shouldn't take you long. I've found MUC very efficient.
