So if the Keeping Up with the Kardashians sisters want to enjoy a sweet treat from time to time, they’ve earned it — and Friday was no exception. The sisters kicked off the weekend by rewarding themselves for another hard workout with some cupcakes at Duff’s Cakemix in West Hollywood, California. The DIY dessert design studio lets the customer be the artist, and Kourtney and Khloé were ready. With Kourtney’s kids Mason, 7, Penelope, 5, by their side, the family got to work — decorating dozens of delicious-looking chocolate cupcakes to their heart’s content. Of course, the reality stars shared all on social media. One cupcake was done up with a heart-eyed emoji face. Another, a shark head swimming in a pool of water according to one shot shared to Snapchat by Kourtney, 38. Kourtney Kardashian/Snapchat Snaps from Khloé, 33, got a little more detailed — showing close-ups of the cupcakes, one decorated as a panda bear and the other, a mermaid. There were a handful of other colorful creations too — including glittery cupcakes that looked too good to eat.
