Manchester United starlet Daniel Nardiello made a sparkling debut after arriving on a month's loan at Oakwell.
The 21-year-old is hoping to play his way to a lucrative new contract at Old Trafford by proving himself in the lower leagues.
And Barnsley profited immediately after the youngster put them back on the promotion trail as the Tykes secured their first victory in seven outings.
The youngster - a prolific scorer in United's youth and reserve teams - grabbed two goals and created another as he became an instant hero with the home crowd.
Nardiello showed pace to create an opening in the tenth minute but his initial shot was blocked by Blackpool keeper Phil Barnes.
But a minute later he showed a flash of brilliance with a cool left-foot first timer from six yards to beat Barnes after Neil Austin had drilled in a low cross.
Blackpool's former Barnsley striker Mike Sheron went close to an equaliser after 20 minutes but keeper Tony Caig did well to save the effort.
Seconds before half time Barnsley could have been further in front but new signing Mark Stallard was off target with a clever curling shot that dipped over the top.
But eight minutes into the second half a mistake by Blackpool's former Barnsley defender Mike Flynn helped the home side to their second goal of the night.
Flynn dithered and the lively Nardiello stole the ball and raced forward, drawing the defence before slipping the ball to Stallard who provided a simple close-range finish for his first Barnsley goal on his home debut.
Sheron was again dangerous as Blackpool looked for a way back but his shot from the edge of the box drifted over the top.
Then in the 61st minute another Nardiello goal killed off the visitors.
Peter Handyside saw his free-kick headed down by Craig Ireland and Nardiello controlled he ball cleverly before racing across the box and cutting in another excellent goal from a tight angle.
