The midfield magician was on another level altogether as he scored two goals and provided another in a seven-goal thriller, which saw the Owls pegged back after taking a two-goal lead before scoring three times in the second half to earn a seventh win in eight games.
Liam Palmer opened the scoring before Bannan converted the first of two wonder strikes.
Goals from Adlène Guedioura and Oumar Niasse got Burton on level terms before efforts from Callum Paterson, Marvin Johnson and Bannan once again helped Wednesday match their best run of form since the promotion-winning 2011/12 campaign.
Here are our player ratings as the Owls march on.
13. Saido Berahino - 7
His introduction helped swing the momentum of the match back in Wednesday's favour. Fired over from close range, but it looked a tough chance. Photo: SWFC
14. Dominic Iorfa - N/A
Replaced Gibson late on for his first appearance since October. Great to see him back and what a lift he could provide. On Tuesday's showing, the defence needs shoring up. Photo: Steve Ellis
15. Ciaran Brennan - N/A
