The sister duo headed to Duff’s Cakemix on Friday (July 28) in West Hollywood, Calif.
They were joined by two of Kourtney‘s children – seven-year-old Mason and five-year-old Penelope (not pictured).
At the bake shop, Khloe took to her Snapchat to share some photos of the cupcakes the group decorated.
Their creations included a super cute puppy cupcake as well as one that was dolphin inspired and a mermaid treat!
“Mermaid life,” Khloe captioned the photo of the cupcake.
