Kevin Nisbet continued his excellent start to the season as Aberdeen finished the Premier Sports Cup group phase with a 100% record after beating Kelty Hearts at Pittodrie.
The Scotland striker knocked in his sixth goal in four games after just two minutes, converting from the penalty spot after a trip on Toyosi Olusanya.
Nisbet then turned provider as his knockdown was bundled in by Kjartan Kjartansson.
Nisbet went close to a second on the half hour when his free-kick rattled against the crossbar.
Olusanya knocked in Aberdeen's third goal early second half as a Tony Yogane cross was pushed into his path by goalkeeper Jamie Smith.
With the Dons cruising, substitute Connor Ronan went close before 15-year-old Andrew Fasanya became the club's youngest ever player, while there was also a debut for Findlay Marshall, who impressed on loan at Arbroath last season.
