The Reds responded with a double substitution at the break as Cornelia Kapocs and Fuka Nagano were introduced.
The half was barely 90 seconds old following the restart before Liverpool were level via Höbinger, with the midfielder making the most of a loose pass by pressing Sunderland on the edge of their own box.
As a result, she won the ball and calmly lifted a shot past the retreating Schumacher to score and even the match once more.
And a short while later, the Reds had put themselves back in front with two goals in just two minutes - making in three goals in 10 - as the game continued its topsy-turvy pattern.
Ramos first produced a piece of individual brilliance, dancing into the area on her own to open up space and fire low into the net.
From the restart, Höbinger then struck her second and Liverpool's fourth, shooting past Schumacher after strong hold-up play from Olsson allowed the midfielder time.
The Reds continued to pile on the pressure with momentum on their side as Ramos went close again, seeing a shot deflect over the bar.
Woodham also had a low effort saved well by the Sunderland goalkeeper, while Mia Enderby's shot from distance was easily halted.
Substitute Neve McDonald then flashed a shot inches past the far post, while another player from the bench in Sophie Roman-Haug worked a final save from Schumacher from inside the box in the last of the action.
