Terry Brown hailed a classic away day performance as the Dons recorded their first win on the road in nearly three months.
Danny Kedwell’s solo winner midway through the second half re-ignited the club’s promotion quest.
Hatters boss Richard Money claimed his side were far superior – despite James Pullen having little work to do in the second half.
Money said: “They have had two shots. To say we had the better chances and more possession is the understatement of the year.
“We’ve had some indifferent performances at home this season but that wasn’t one of them. I thought we were outstanding, fantastic.
“Hopefully they (Wimbledon) understand that they were second best today.”
But Brown, celebrating a first away victory since the December 1 success at Salisbury, responded, saying: “I thought it was the perfect away display.
“It must be very frustrating for him (Money) There were nearly 8,000 in the ground and there’s no doubt we played better here than we did at Cambridge. We’ve had clubs raising their game for years!
“You can’t come here and go hell for leather. There were a lot of threats to contend with and we coped well.
“We may not have created an awful lot but we took our chances. I have told the players now to make sure this isn’t a one-off good result. Use it as a platform.”
Wimbledon took the lead against the run of play with the Hatters enjoying more of the early exchanges.
In the 28th minute Will Hendry did well wide right and his cross found its way to Nathan Elder who half hit the close-range shot – the ball eventually squirming over the line despite Mark Tyler’s best attempts.
But straight away Wimbledon lacked focus. Hatters captain Kevin Nicholls was given too much space and Tom Craddock made the most of the chance, sweeping home his low shot within 30 seconds of the re-start.
With seven minutes to go before half-time, Elder could have made it 2-1. Steven Gregory’s cross was good but the on-loan striker opted for placement over power, nodding down and the wrong side of the near post when totally unmarked.
Luton had the vast majority of second half possession but the Dons boasted the match-winning chance.
Elder set free Kedwell on the left, injuring himself in the process.
So Kedwell went it alone, brushing aside Janos Kovacs before closing in on goal – the top scorer found the top corner for a truly wonderful winner.
Luton had their chances to level but Rossi Jarvis headed straight at James Pullen and stand-in right-back Adam Newton had all the composure of a defender by missing the target by five yards when one-on-one.
