- Liquid Death and MrBeast's Feastables released a Peanut Butter Cup flavored sparkling water on August 4, 2026, after first teasing it back in October 2025.
- Each 12 oz. can has 10 calories and 2 grams of sugar, with no caffeine or artificial sweeteners, and it's allergen-free despite the peanut-butter-cup flavor.
- A new ad shows MrBeast buying "the world's most dangerous biker bar" to introduce its regulars to the drink.
Liquid Death and MrBeast’s candy brand Feastables have turned one of Feastables’ best-selling treats into a canned drink.
The two companies rolled out the Liquid Death x Feastables Peanut Butter Cup Flavored Sparkling Water on August 4, 2026, after first teasing the idea at a trade show back in October 2025, with an expected Halloween 2026 launch window that ended up arriving early.
Each 12-ounce can has just 10 calories and 2 grams of sugar, with no caffeine and no artificial sweeteners. Despite the name, the drink is allergen-free and contains no actual peanuts, so people with nut allergies can try the flavor too.
To promote the launch, MrBeast stars in a new ad where he buys what the brand calls “the world’s most dangerous biker bar” and introduces its rowdy regulars to the sparkling water, closing with the tagline “Because nothing says tough like peanut butter cup.”
The drink is available now on Amazon as a 12-pack, plus single cans at 7-Eleven, with a wider rollout planned at Five Below while supplies last.
This isn’t Liquid Death’s first left-field flavor swap. The brand has turned Fruity Pebbles into cereal milk water and Van Leeuwen ice cream into a Hot Fudge Sundae can, and in May it had Colby Minifie, in character as The Boys’ Ashley Barrett, front its Sparkling Energy line.
For MrBeast, the tie-up follows a busy year of brand moves, including an expanded partnership with Lowe’s for kids’ building workshops announced in May.
The collab also lands in a summer packed with celebrity flavor drops. Becky G partnered with Alani Nu on a limited Purple Cotton Candy energy drink, a reminder that brands keep leaning on famous faces to sell new flavors.
Takeaways
MrBeast keeps finding new ways to stretch Feastables beyond candy bars, and this time he’s letting another brand borrow the flavor instead of building the product in-house.
For Liquid Death, pairing with the internet’s biggest creator is another shot at an audience it doesn’t always reach through skateboard decks and enema kits.
And the fact that this rolled out months ahead of its original Halloween target hints that retail demand may have outpaced the marketing calendar.
Would you actually try a peanut-butter-cup-flavored sparkling water? Could this “limited edition” flavor stick around if it sells well enough? What snack would you want Liquid Death to turn into a drink next?
