Liquid Death’s latest collaboration taps a popular YouTuber and his snack brand for a new candy-themed beverage.

The water brand has teamed up with MrBeast on a limited-edition flavored sparkling water, Liquid Death x Feastables Peanut Butter Cup flavored sparkling water. Except this version, unlike an actual peanut butter cup, is allergen-free and low calorie, so those with any sort of peanut allergy or dietary concerns can also indulge.

Jimmy Donaldson himself, aka MrBeast, and his crew star in an over-the-top spot for the canned water, seen here.

It opens on Donaldson standing in a dive bar, introducing it as if it were one of his challenges: “I just bought the world’s most dangerous biker bar.”

A leather-clad biker steps up to the bar demanding, “Give me the strongest stuff you got, video boy,” as Donaldson passes him a can of Liquid Death x Feastables Peanut Butter Cup.

The bar erupts in silly, jubilant chaos as the tough guy downs the sparkling water along with all the other bikers. The members of Donaldson’s somewhat nerdy crew and the bikers unite under their shared love for the peanut-butter-cup-flavored water, closing with Donaldson saying, “Cause nothing says tough, like peanut butter cup.”

“Pretty much everyone who has ever been a child loves chocolate and peanut butter together. But once you get older, you don't enjoy it nearly as much,” Andy Pearson, Liquid Death's vice president of creative, told Marketing Daily. “So we decided to show the scariest, most serious people you'd come across enjoying it. Plus, the drink is peanut-free and has just 10 calories, so everyone can enjoy as much as they want.”

The spot runs online, as well as across both brands’ socials.

Donaldson launched Feastables as a “mission-driven snack and chocolate brand” in 2022 with such items as Milk Chocolate Crunch bars and gummies, along with Peanut Butter Cups. The brand, which touts using ethically sourced ingredients, hit $250 million in annual revenue by 2024.

Liquid Death reached a $1.4 billion valuation earlier this year, reporting  annual retail sales of over $1 billion for 2025.
