The Bavarians hosted their Wildenau-based supporters and were already 3-0 up in the first period, thanks to goals from Thomas Muller as well as youth prospects Oliver Markoutz and Vladimir Rankovic.
Die Roten opened the floodgates in the second-half as Patrick Weihrauch, Julian Green, Franck Ribery, Mitchell Weiser and Toni Kroos struck.
Germany Under-19 international Weihrauch will have done his first-team prospects no harm after his four-goal haul, while fellow starlet Green, who was born in Florida, impressed with his display and subsequent hat-trick.
Guardiola will also be pleased to welcome back Kroos, after the playmaker missed the tail-end of last season through injury.
