Harry, 19, had a go at making Hawaiian pizzas from scratch with 14-year-old Presley and his two friends, and his 12-year-old sister Kaia.
The One Direction heartthrob, who is currently performing with the band on their Take Me Home world tour, seems to have been a hit at the cooking session.

"Thanks for stopping by the house again and helping the boys and I make our pizzas @harrystyles," wrote Presley, alongside a photo of the gang in the kitchen.
"Anytime brother. See you for surfing soon," replied Harry.
The pop sensation then posed with Kaia and her friend in another photo, in which the singer's swallow tattoos on his chest can be seen peeking out of his shirt.
"Thanks for coming by again @harrystyles and giving my friend, Ava, a mini heart attack...," wrote the 12-year-old, alongside the Instagram photo.
This is not the first time Harry has hung out with Cindy's children. The One Direction star stopped by Cindy and her husband Rande Gerber's West Hollywood home earlier in August, shortly after Presley had a tonsil operation.
Harry again posed for photos with the two youngsters, which Presley was quick to post online.
"I was chilling at my house after I got my tonsils taken out and my sister had a friend over to hang," wrote Presley, alongside the snap of himself and Harry.
"This guy knows how I feel," he posted again, next to a photo of Harry imitating the teenager's throat pain.
