Kraft Heinz has announced a new seasonal product in partnership with PepsiCo’s Walkers brand: Heinz [Scarily] Good Monster Munch Mayo. The limited-edition release fuses Heinz’s signature creamy mayonnaise with the bold, nostalgic flavour of Pickled Onion Monster Munch, aiming to tap into Gen Z interest and Halloween-driven novelty.

The collaboration marks another strategic move by Kraft Heinz to expand its footprint in occasion-based condiments and flavour mash-ups. According to Thiago Rapp, Director of Taste Elevation at Kraft Heinz, the goal was to deliver a product that’s “a scarily good twist on the classic,” building on the success of last year’s Heinz Black Garlic Mayo.

Wayne Newton, Senior Marketing Director at Walkers, added: “We’ve taken it a step—or claw—further with this collaboration. It’s a new way for consumers to enjoy the distinctive taste of Pickled Onion Monster Munch, just in time for Halloween.”

This is the second collaboration between Heinz and Walkers in recent months. In September, the brands launched a line of sandwich-inspired crisps, including flavours such as Roast Chicken & Heinz Mayo and Cheese Toastie with Heinz Beanz.

The new Heinz [Scarily] Good Monster Munch Mayo hits UK supermarket shelves from 24 September at an RRP of £2.40.
