The reigning champions successfully defended their crown in a record number of matches, having sewn up the title race by early March following a storming domestic campaign.
The Champions League holders were thrashed by Real Madrid in the last four of this season's tournament, prompting criticism of Guardiola's tactical approach, but the former Barcelona boss maintains the league title was the most important to him in his first senior coaching campaign away from Spain.
"I'm happy and very proud of the whole club this season," Guardiola said at a press conference. "Maybe for some people it's just another Bundesliga title but for me it's my first one.
"It's the most important title this term.
"Winning your domestic league is always the best title because you have to play week after week."
Bayern finish their league campaign against Stuttgart this weekend and Guardiola revealed Holger Badstuber may play some part in the game after recovering from two serious knee injuries.
"We're very happy that Badstuber has trained with us again," he added. "I won't take any risks with him.
"He might be on the bench."
