Aberdeen boss Derek McInnes praised his scoring substitutes Scott Vernon and Gregg Wylde following
Vernon came off the bench to net a stunning effort with 10 minutes to go, before setting up Wylde's first goal for the club to move Aberdeen up to second in the league.
"It shows the strength of the squad," McInnes told BBC Scotland.
"From start to finish we dominated it. We didn't have a failure in the team."
The Dons had passed up a glut of chances, with Niall McGinn and Calvin Zola spurning second-half chances.
However, Vernon finally broke the deadlock, grabbing his fifth goal of the season when he curled home from the edge of the area.
James Collins could have levelled for Hibs in a frantic finale but failed to take advantage of an error by Jamie Langfield.
Vernon then turned provider in time added on, setting up Wylde to finish low in to the left hand corner.
"It was a performance that was needed to overcome a resilient Hibs team," said McInnes.
"We were just looking for that cutting edge, and passed up ample opportunities.
"Just when you start to think maybe it is not going to be your day, Scott Vernon comes up with a real piece of quality. It's a top, top finish.
"From then on in he plays his part in Gregg Wylde's goal, and I think 2-0 was a fair reflection of the game.
"Substitutes have got a huge part to play. Scott's come off the bench previously and scored goals for us and none better than today."
Gregg Wylde has cut a frustrated figure on the bench in recent weeks, but his manager said his goal was deserved for his attitude.
"In the past few weeks he has been more like himself," added McInnes. "He has been really positive in training.
"He had an U20s game against Hearts in midweek and scored in a 5-0 victory. From then on in he seems to have that wee spring in his step again, and he took his goal brilliantly."
