What Happened to Peanut Butter Twix?
Peanut Butter Twix is a U.S. Twix variation that replaces the usual caramel layer with peanut butter. Over the years it has gone in and out of wide distribution, which is why many shoppers remember it as a candy bar that keeps disappearing and returning. Mars confirmed another return in 2017, and the flavor remains one of the best-known Twix variants outside the original caramel bar.
ℹ️ Fate: Still part of the broader Twix flavor lineup, but its shelf presence has varied over time. Mars has brought it back after previous gaps in distribution, including a confirmed return in 2017.
Peanut Butter Twix is one of the most remembered Twix variations in the United States. Instead of the usual caramel layer, it uses peanut butter while keeping the basic Twix idea of a cookie-based bar covered in milk chocolate. That simple change gave the brand a strong fan base and made it feel familiar but different enough to stand apart from the original.
What makes Peanut Butter Twix especially notable is that its history is not one clean run. The flavor has gone in and out of distribution over the years, which is why so many people remember it as a candy bar that was always either returning, disappearing, or rumored to be coming back. That stop-and-start history is a big part of its identity.
The strongest easy-to-verify official milestone is 2017, when Mars Chocolate North America announced that TWIX Peanut Butter would return to stores in September. That confirmed what many fans already knew: Mars saw the flavor as valuable enough to bring back even after earlier gaps in availability.
That kind of return pattern helps explain why Peanut Butter Twix has lasted in memory so well. It is not just a flavor variant. It is also a comeback candy. Fans tend to talk about it less like a permanent shelf staple and more like a bar they are always happy to rediscover.
The safest way to describe Peanut Butter Twix today is as a recurring Twix variant with uneven visibility. It belongs to the active Twix family, but depending on the year, retailer, and assortment, it can feel either easy to find or strangely absent. That uneven availability is one reason it still gets searched so often.
