Kim and Khloe Kardashian Epically Attack Mom Kris Jenner With Cake -- Watch! (Exclusive)

E!

The messy moment goes down on the next episode of ‘Keeping Up With the Kardashians.’

Kim and Khloe Kardashian are out for sweet revenge -- literally.

ET has your exclusive first look at Sunday’s all-new episode of Keeping Up With the Kardashians, which finds the sisters plotting against their mom, Kris Jenner. Kim and Khloe are gathered in Kris’ pristine kitchen, armed with two identical cakes from the family’s favorite bakery. One cake is topped with cookies that read, “Sweet Revenge” and “How Does Payback Taste?” Cryptic!

Khloe calls Kris into the kitchen, much to Kris’ surprise. The sisters then tell their mom that they wanted to “truly thank” her for “just being you.” That’s when Kim grabs her mom for a hug -- and chaos erupts. As soon as Kim has Kris in a tight embrace, Khloe lifts up one of the cakes and drops it directing on the 62-year-old matriarch's head!

“Khloe, what is wrong with you?” Kris screams out. “What the hell are you doing?”

The sisters then point out the cryptic cookie messages on the remaining cake, which only confuse Kris.

“You’ve been manipulating all of us and using your daughters to buy you s**t!” Khloe tells her mom. “Are you crazy?!”

Kris has seemingly been pitting her daughters against each other in what Kim calls a “scam,” telling each daughter that one of their sisters purchased her certain gifts. Kim caught on to Kris’ game after Kris told Kim her new toaster was a present from little sister Kylie Jenner. Kim asked Kylie if that was true and Kylie denied it.

“You’re teaching us bribing, lying, scamming…” Kim tells Kris, but Kris cuts her off to say, “They’re life lessons. Don’t ever forget.”

Kim then says Kris can buy herself a mop to clean up the mess left by the cake smash, which Khloe only makes larger when she launches the second cake at Kris, telling her mom she doesn’t “deserve” it.

“This is bad behavior!” Kris shouts.

“This will show her not to mess with us again!” Khloe says in a confessional. “You’re gonna get two cakes to the face, Kris! We’re big and we’re bad. And we’re hungry.”

Hungry, indeed. Kim and Khloe then sit down to eat the cake off of the floor together, a la Rachel and Chandler on Friends. They invite Kris to join, but she denies their offer.

“No, I don’t want a piece,” she announces. “I have cake up my nostrils! You guys are both grounded.”

“You’re a scam artist,” Khloe replies, as Kris walks away.
