Mondelēz launches Toblerone Biscoff truffles at Costco

Mondelēz International announced the global launch of Toblerone Diamond Truffles with Biscoff on September 22, 2026. The new confection combines milk chocolate, Biscoff spread, and honey-almond nougat pieces into a diamond shape, extending a truffle format that Toblerone first launched in 2024.

The release marks the first global retail partnership between Mondelēz and Costco. The retailer will exclusively carry a 495g premium box across ten markets: the United States, Canada, Taiwan, Australia, the United Kingdom, Spain, France, Sweden, Iceland, and New Zealand.

Mondelēz is also releasing a smaller 180g sharing box in the United Kingdom, Ireland, Switzerland, and Australia, with plans to expand to more markets later. The collaboration with Lotus Bakeries targets growing consumer demand in the premium boxed chocolate segment, which continues to outpace wider confectionery growth.

Mondelēz, which generated approximately $38.5 billion in net revenue in 2025 and sells products in more than 150 countries, produces up to 4 million Toblerone items each day in Bern Brünnen, accounting for roughly 90% of worldwide Toblerone production.
