Toni Kroos, Mario Gotze and Franck Ribery scored in a 3-1 win at Hertha Berlin, which means Bayern defended their Bundesliga title with a whopping seven games to spare.
They have become the first Bundesliga winners in March and have now won 19 consecutive top flight matches, with an unbeaten record that sits at 52.
Guardiola's team had more than 1,000 passes and showed all the hallmarks of the Spaniard's trophy-laden reign at Barcelona.
He said: "Everything has come together for us. We've played phenomenal football this season.
"I don't think this would have been possible (for a Bundesliga side to win the title in March), but we're delighted.
"We're so happy to have Pep Guardiola here. He's evolved our game even further."
Ribery sealed the victory with an exquisite late chip, a goal that settled Bayern nerves after Adrian Ramos' second-half penalty.
And the Frenchman said every member of Bayern's squad can feel proud of their efforts as their unbeaten run continued.
"It's unbelievable to clinch the title on the back of an unbeaten record," Ribery stated.
"We're all unbelievably proud of the team and our achievements this season."
