The Canaries set the tone for the afternoon inside the opening 40 seconds, when Mo Toure's thumping strike gave them the lead after Kenny McLean slotted him in behind the MK Dons defence.
Their slick attacking play continued and saw the Australian international striker turn provider as he chopped the ball into the path of Anis Ben Slimane, who turned inside his man before tucking the ball past Craig MacGillivray to double their lead inside seven minutes.
City's dominance and intensity continued, and they added a third before the interval. Andre Brooks latched onto a cutback, only for his strike to deflect off colleague Ben Chrisene and loop into the top corner of the net.
A crazy 10-minute spell in the second half saw MK Dons miss a penalty, score to reduce the deficit, all before Norwich added a fourth goal to kill off the contest.
Callum Paterson was bundled over inside the Canaries box after a deep free kick, but Vladan Kovacevic superbly denied Nathaniel Mendez-Laing from the spot. From the resulting corner, Ryan Wintle volleyed into the net to prevent Philippe Clement's side from earning a clean sheet.
It took just three minutes for City to reclaim their three-goal advantage, when a poor defensive pass was seized upon by Brooks, who ran through and coolly slotted the ball into the net to mark his debut with a goal after a ÂŁ8m move from Sheffield United earlier this summer.
City will now focus on their Championship opener against West Brom at Carrow Road next Saturday, hoping to take momentum from a convincing League Cup victory.
