The Germany international has been out of action due to a hip injury ever since the 2-0 Champions League win at home over Juventus on April 2, but he's hopeful of returning to match action this season.
"I want to be back as soon as possible. The healing process is going well. We're making progress step-by-step," Kroos told reporters. "I'm dreaming of the cup final, but it would be ridiculous to assume anything.
"When you look at what we've invested in the competition, we really, really want to win the DFB Pokal."
Bayern last won the German cup in 2010 when it beat Werder Bremen 4-0 in the final. The club was beaten 5-2 by rival Borussia Dortmund last season
