Trump, 22, added the UK crown to the China Open success he achieved just prior to heading to the Crucible in April.
The 22-year-old from Bristol fended off a sparkling evening revival from Allen, who rifled three century breaks in four frames, to win 10-8 and carry off the silverware and a cheque for £100,000.
"To win it the way I did is a brilliant achievement," Trump said.
"Mark pushed me all the way. It's a good job I had a big lead in that last session."
The Barbican Centre crowd were wowed by a match-defining run from Trump of seven frames in a row which took him from 3-1 behind to 8-3 ahead and left Allen with too much ground to make up.
Allen went close to pulling off the spectacular comeback but he rattled a long red in the jaws of a corner pocket at the start of frame 18 and Trump, having spent so much of the evening in his chair, seized his big chance with a rapid match-clinching 91 break.
It was Allen's first major final in his career and it came at the end of a week when he caused controversy away from the table.
Allen called for World Snooker chairman Barry Hearn to quit and faced the possibility of legal action from the veteran sports promoter, who took offence at the 25-year-old's remarks.
The row was defused on Sunday when Hearn said he would happily meet with Allen at the World Snooker AGM later this month, and Allen said he would rather enter face-to-face talks than head to court.
