Arsene Wenger handed a debut to new signing Petr Cech and saw goals from Theo Walcott, Santi Cazorla and Mesut Ozil secure his side victory in front of a crowd of 53,000 at the National Stadium.
Everton midfielder Ross Barkley scored a late consolation, but the result was never in doubt.
Walcott's pace took him clear of Everton defender Seamus Coleman in the 22nd minute and the Arsenal striker was able to toe-poke home the game's opening goal.
Cech pulled off a fine save to push Steven Naismith's first-half effort on to the crossbar, but Cazorla cut inside on the edge of the penalty area to drill home a low shot and double Arsenal's lead in the 58th minute before Ozil slotted home a third four minutes later.
Barkley's emphatic finish made it 3-1 in the 75th minute, but it did little to paper over what had been a disappointing Everton display.
Arsenal had sealed their place in the final by beating a Singapore Select XI 4-0, while Everton won through against Stoke after a penalty shootout.Reuse content
