Wednesday arrived at Elland Road on the back of three straight wins but Leeds ultimately proved too strong.
After Butler headed home Jonathan Douglas' hooked cross, Cresswell added a header of his own from Gary Kelly's corner before adding an injury-time tap-in.
Blackwell: 'That's the dream for everyone - to play against your old club and be man of the match with a couple of goals. He'll have a good weekend, I think. The three points were vital and I felt we looked a good strong team today and showed no signs of tiredness from the Wigan game on Tuesday.
'I thought 3-0 was a fair result and am pleased with the attitude of the players.'
Owls boss Paul Sturrock felt there was several positives to come out of the defeat.
Sturrock: 'In the end the first goal was key, but I didn't feel it was a 3-0 result. I'm not downhearted and I've learned a few things today about my players.
'I've learned we are not a 4-3-3 team, but needs must today because we needed to get up there in their faces.
'You probably learn more in defeat than you do when you win. We're going to get healthier now because we've got 10 days without a game and we live to fight another day.
'The result will be hard for our fans to take because they were magnificent today and will find losing to one of their deadliest rivals a bitter pill to swallow.'
