KFC has introduced a new limited-time drink in partnership with Mountain Dew: Sweet Lightning Peaches & Cream.
The beverage, which launched nationwide on June 9, 2025, is an updated twist on the original Sweet Lightning flavor first released in 2019. The new version adds a creamy vanilla flavor to the familiar peach and honey base, turning it into a “dirty soda”, a nod to the viral TikTok trend of mixing soda with syrups and cream.
The Peaches & Cream version is available with or without a swirl of vanilla cream and is being marketed as a summer-exclusive, while supplies last.

The launch is part of KFC’s larger summer promotion campaign, which also includes a tie-in with the upcoming Brad Pitt-led “F1: The Movie” and the return of the popular $7 Fill Ups meal deal. That deal includes a choice of one of four value meals: two-piece drum and thigh, three tenders, chicken sandwich, or Famous Bowl, each served with mashed potatoes and a biscuit.

Mountain Dew, meanwhile, is continuing its streak of fast-food collaborations. In past years, the soda brand has launched exclusive flavors like Baja Cabo Citrus Blast at Taco Bell and Mango Gem at Little Caesars.
