Liquid Death Just Dropped Chocolate Peanut Butter Cup Water

Just when it seemed like food collaborations couldn’t get any stranger, Liquid Death and MrBeast proved everyone wrong. The two brands have teamed up to create a Peanut Butter Cup Flavored Sparkling Water. It sounds like a prank that somehow escaped the group chat, but this limited-edition drink is very real.

If drinking a peanut butter cup sounds a little wild, that’s exactly the point. Liquid Death has built its name on doing the unexpected, and teaming up with MrBeast’s Feastables might be one of its boldest ideas yet.

Peanut Butter Cup In A Can

Liquid Death and Feastables have teamed up to launch the new limited-edition Peanut Butter Cup flavored sparkling water. It’s inspired by Feastables’ Peanut Butter Cups, which are made with creamy peanut butter and real milk chocolate.

Liquid Death says those sweet, chocolatey flavors have been packed into sparkling water, creating a drink that tastes like the candy without actually containing peanuts. That also means it’s allergen-free, giving people with peanut allergies the chance to enjoy a peanut butter cup-inspired flavor for the first time. 

Despite the dessert-like flavor, the nutrition label is surprisingly light. Every 12-ounce can has just 10 calories, 2 grams of sugar and no artificial sweeteners. So while it may taste like candy, it drinks more like flavored sparkling water.

Fans Still Can’t Decide

Ever since rumors of this collaboration first surfaced in late 2025, people have wondered one thing: What does chocolate peanut butter sparkling water actually taste like?

Now that the drink has started reaching stores, early reactions have been all over the place. Some shoppers say it actually captures the flavor of a peanut butter cup, while others admit it sounds strange but are curious enough to give it a try. And then there are those that just say “hell no” at the idea, either because they don’t just like the product or MrBeast himself.

Regardless, I think Liquid Death and MrBeast have done what they do best, which is to create a product that gets everyone talking before they’ve even tried it.

Here’s Where To Find It

The limited-edition Peanut Butter Cup Flavored Sparkling Water is available now on Amazon, with more cans rolling out to grocery stores and retailers like while supplies last.

Whether it becomes a surprise hit or simply goes down as one of the strangest drink releases of the year, there’s no denying it’s different from almost everything out there.
