Geisenberger was victorious last time out in Koenigssee, that her third World Cup win of the season, ahead of German team-mates Carina Schwab in second and Aileen Frisch in third.
And there was to be no denying Geisenberger or Germany as the circuit moved across the nation to Oberhof with the 24-year-old the winner and two of her compatriots on the podium.
Tatjana Hufner and Anke Wischnewski finished second and third respectively with another German, Dajana Eitberger, fourth and Geisenberger returning the European title to the country.
Russia's Tatiana Ivanova arrived as the two-time defending European champion but it was clear from the off that Geisenberger, the 2008 champion, would dethrone her as she finished 11th.
She topped the time sheets at the end of run one after clocking 41.764 and then maintained her lead with an effort of 41.833 second time out for an overall winning time of 1:23.597 minutes.
Hufner was second after run one and remained there while Wischnewski was third throughout, Eitberger was fourth throughout and the first non-German Alex Gough was fifth for the duration.
Hufner finished 0.187 behind Geisenberger with Wischnewski a further 0.112 adrift with the margin thereafter between her and Canadian Gough in fourth 0.105.
