The unnamed Brit was caught with around €160,000 - €200,000 worth of crystal meth trying to get through secutity, reports the Münchner Abendzeitung.
Customs officers at the airport found the drugs in the woman's hand-luggage.
The meth had been carefully divided up, and wrapped up in a variety of sweet wrappers.
Customs officers became suspicious at the vast quantity of "bon-bons" the woman was taking on her journey – and after an examination of the contents, the drugs were seized.
The woman is believed to have entered Germany from Lisbon.
Currently in custody, she is likely to face a prison sentence of at least two years.
