Germany's perennial champions missed out on lifting the cup over the past three seasons, but they are now clicking into top gear, having scored 11 times in their last two games.
Match preview
Fresh from their 14th straight Champions League group-stage win in midweek, Bayern Munich welcomed VfL Bochum to the Allianz Arena on Saturday afternoon and dealt out a familiar beating to their visitors from the Ruhr region.
Days after Thomas Tuchel's men posted a 4-3 home win over Manchester United, they ruthlessly dispatched domestic opponents who lost 7-0 in Munich last season, as Harry Kane's first hat-trick for the club helped his side smash seven past Bochum once again.
Kane also found time to lay on two assists as he surpassed a record jointly held by Gerd Muller, Miroslav Klose and Mario Mandzukic, taking his tally to seven goals in five Bundesliga matches to start his Bayern career.
Now, ahead of Saturday's league clash with RB Leipzig, Die Roten must take care of business in the rather less glamorous surrounds of the 14,300-capacity Preussenstadion, where their first-round tie in the DFB-Pokal will take place.
Given their ongoing dominance of the Bundesliga, Bayern have been relatively unsuccessful in their national cup in recent times, having failed to make the last three finals and lifted the trophy only two times in the past seven years.
The Bavarian giants will no doubt seek to change that trend this season, which they have begun in menacing style: after starting with a shock 3-0 Super Cup loss to Leipzig in August, they have since won five of their last six matches, scoring 22 goals and netting at least twice on each occasion.
While Bayern moved top of the Bundesliga standings with their battering of Bochum, their cup hosts currently occupy a far more modest 14th place in German football's third tier.
Having won only two of their first seven league matches this term - averaging just one goal per game - Preussen Munster will surely head into their first-round tie with some trepidation.
Founded in 1906, and an original member of the first Bundesliga back in 1963, the North Rhine-Westphalia club have plenty of history to reflect on, but in recent decades they have languished in the lower leagues.
Beating SV Sandhausen and holding VfB Lubeck to a 1-1 draw in their last two outings may boost confidence in the camp, but coach Sascha Hildmann - who led Die Adler out of the Regionalliga last season - has his work cut out to suppress the irresistible force of Bayern Munich.

Ahead of an important league game at the weekend, Bayern boss Thomas Tuchel is sure to make several changes at Preussenstadion, with Harry Kane likely to be rested after his action-packed start to life in Germany.
Kane was joined on the scoresheet by fellow forwards Mathys Tel and Eric Maxim Choupo-Moting against Bochum, and the latter pair could now join forces on Tuesday night.
The visitors are still without veteran goalkeeper Manuel Neuer, while Raphael Guerreiro is yet to return from a calf injury, but Tuchel should otherwise have a full squad to choose from.
After featuring as a substitute on Saturday, young Franz Kratzig could be among those drafted into Bayern's starting XI, alongside Senegalese right-back Bouna Sarr.
Preussen Munster, meanwhile, will make no such changes, as Sascha Hildmann selects his strongest available side.
Joel Grodowski impressed in Die Adler's 1-1 draw with Lubeck, and the former Bradford City striker should partner Malik Batmaz up front; however, for the sixth time this season, Gerrit Wegkamp made a substitute appearance on Saturday, and having scored a header within five minutes of his introduction could now press for a start instead.
Munster-born midfielder Marc Lorenz, who is the hosts' club captain, may also play a part, while ex-USA international Andrew Wooten offers an alternative attacking option from the bench.
Preussen Munster possible starting lineup:
Niehues; Koulis, Kok, Hahn; Kyerewaa, Preissinger, Bazzoli, Lorenz, Bockle; Batmaz, Grodowski
Bayern Munich possible starting lineup:
Ulreich; Sarr, Upamecano, Kim, Kratzig; Laimer, Goretzka; Gnabry, Choupo-Moting, Muller; Tel
