The Liverpool Boys star equalled Rooney's record from the 1996/97 season - achieved with the same team - with two matches left to play.
He then broke it with a goal in the North West Cup Final against Macclesfield before ending his season with a hat-trick against Wirral to sign off a 76-goal season.
"I never thought I would get anywhere near the record at the start of the season," said Garner. "I didn't even know there was one until much later!"
The incredible season has helped his side win all 39 of their matches this season, with the star player himself notching eight hat-tricks as they collected an astonishing nine trophies. Among those hat-tricks he scored four in a match on three occasions and five twice.
The Kirkby-born left-footer attended the same school as Rooney - Our Lady & St Swithun's primary school in Croxteth - and is heading to the same secondary school in September, and is already being tipped to follow the Rooney path to a glorious career.
Yet the lifelong Liverpool fan - who signed for the club at age six - actually prefers Spanish striker Fernando Torres to the England talisman.
"Wayne is a great player and I enjoy watching him," he explained.
"But I have been signed up by the Liverpool Academy and really like Fernando Torres.
"For me, he is my sort of striker and I love to watch him play and score."
And despite his exploits, the boy they nickname 'Jazza' still has his size-five boots well and truly on the ground.
"I'm only part of a team and I want to thank my team-mates for helping me break the record, and those who coached me," he added. "I couldn't have done it without them."
