What Happened to Peanut Butter Twix (Twix PB)?

1983–? Food/Confectionery • United States

ℹ️ Fate: Ongoing in the U.S. with periodic reformulations and packaging updates; availability has varied by region and year.

First sold in the U.S. in the **1980s**, **Peanut Butter Twix** (often labeled **Twix PB**) swaps Twix’s caramel for a **peanut-butter layer** over a **chocolate cookie**, enrobed in milk chocolate. The SKU has cycled in and out of national distribution—**discontinued in the late 1990s**, revived in the **2000s**, and widely reintroduced around **2014**—but today remains a recognized, rotating core flavor alongside Caramel.

Peanut Butter Twix (aka Twix PB) is the long-running peanut-butter spin on Mars’ biscuit-bar classic. Instead of caramel over a shortbread finger, PB Twix uses a peanut-butter layer on a chocolate cookie base, then coats the bar in milk chocolate. U.S. shoppers first saw it in the 1980s, it went missing in the late 1990s, returned in the 2000s (with packaging shifting between “Twix PB” and “Peanut Butter Twix”), and by the mid-2010s it was back in broad distribution. Availability still varies by retailer and season, but as of 2025 it’s commonly found in standard and share sizes.
