The reality stars were joined by mates as well as sisters Khloé, 28, Kendall, 17, and Kylie, 15.
Mum-of-two Kourtney looked cute in an all-denim outfit as she took part in the friendly competition.
Uploading snaps to Instagram, she showed off her 10-pin skills as well as a girly cake covered in edible roses.
‘Happy Birthday to me Happy Birthday to me,’ she posted.
‘Original DASH dolls hit the lanes. Better than when we were hitting the clubs.’
Kim took her own photos of the event too, sharing shots of Kourtney and the group.
‘Kisses to the Birthday girl @kourtneykardash,‘ she wrote.
