The Englishman was heavily favoured to do the business, in front of his home fans at a soggy Wembley Stadium on Sunday morning (NZ time), and the 28-year-old proceeded to maintain his flawless professional fight record (now 22-0) in keeping his WBO, IBF and WBA belts safe.
And as he was handed a microphone for a post-fight interview, Joshua revealed his number one target for his next fight - April 13 at Wembley - is Wilder, the man who has so far evaded his clutches.
Joshua first wobbled Povetkin with a right hand, followed by a left before the telling left hook and right hand sent the challenger crashing to the canvas.
Previously convicted for his doping offences, many had felt it would be something of an aberration had the Russian fighter claimed the win on the night.

LONDON, ENGLAND - SEPTEMBER 22: Anthony Joshua celebrates victory over Alexander Povetkin during the IBF, WBA Super, WBO & IBO World Heavyweight Championship title fight between Anthony Joshua and Alexander Povetkin at Wembley Stadium on September 22, 2018 in London, England. Anthony is a very strong fighter but I am just as strong.
"I have lived and worked in the United Kingdom for 20 years now and am proud to call myself an adopted Englishman, my wife and children are English so am a little bit torn between these two fighters". And if it is not Wilder next up, Joshua could find himself facing the 27-0 Tyson Fury after Povetkin. You can't beat me. Joshua jumped on Povetkin with another combination that forced the referee to jump in and stop the fight.
Asked who would win between Wilder and Fury, Joshua replied: "I'm not too fussed who wins, I only concentrate on myself".
"We both showed that against Klitschko, dug deep and stayed in there. If it's not Deontay Wilder then it will be Dillian Whyte on April 13".
