Neuer turned over a dipping strike by Robert Lewandowski, stopped a Jakub Blaszczykowski shot with his legs, blocked Sven Bender's snapshot and a Marco Reus effort as treble-chasing Bayern wobbled.
Dortmund goalkeeper Roman Weidenfeller was also called into action, tipping a Mario Mandzukic header on to the crossbar in the 27th minute.
As Bayern enjoyed some dominance, Arjen Robben got clear on the right but attempted to dink his shot over Weidenfeller who turned away the effort for a corner.
Then it was Neuer's turn again as he saved with his legs from Lewandowski after a Dortmund counter-attack.
