Sister, sister! Kim Kardashian gifted her sister Kourtney with a sweet, nostalgic birthday present for her 37th birthday back in April, and Keeping Up With the Kardashians captured the moment in a never-before-seen clip.

In the video, Kim, 35, Kourtney, and their pals are dining in Iceland when the Selfish author presents Kourtney with a gift bag. Inside, the eldest Kardashian sister finds a Snoopy Snow-Cone Machine, a relic from their childhood.

“All we wanted to do was go to MJ’s house,” Kim explains to everyone around the table as Kourtney smiles and turns the present over in her hands. “My grandma worked and my grandpa didn’t, so my grandpa would sit at home with us and make those with us all day long. All we wanted was a Snoopy snow cone.”

“That is so cute!” Kourtney exclaims, adding with a slight eyebrow raise, “We should make it for the hot tub later.”

During the birthday dinner, Khloé, 32, calls in via FaceTime and explains to Kourtney that she tried to tell Kourt’s ex Scott Disick not to post a throwback photo on Instagram of the couple making out as a tribute to her birthday.

“I told him not to [post it],” the former Kocktails With Khloé host says. “Because I said you guys are making out, that kind of like, gives it a weird impression. I told him no, like, four times but he was determined.”

The dinner ends with just one more surprise: a brightly lit birthday cake, which Kim presents to the table as “your vegan-free, dairy-free cake.”

The health-conscious mother of three carefully counts the candles on the cake and declares, “I’m 7 years old today, guys!”
