BURLINGTON, VT. — Ben & Jerry’s has expanded its line of dairy-free frozen desserts with a vegan version of its popular chocolate chip cookie dough variety. Another dairy-free option, chocolate caramel cluster, also joins the lineup.

“Ever since we introduced non-dairy in 2016, our fans have been clamoring for more,” said Sarah Fidler, a research and development specialist and “flavor guru” at Ben & Jerry’s. “The biggest challenge this time was creating a chocolate chip cookie dough flavor that stood up to the original. I think we nailed it.”

Ben & Jerry’s now offers 11 non-dairy flavors, including Cherry Garcia, Chunky Monkey and Cinnamon Buns, and another non-dairy innovation is scheduled to be announced in early spring. The products feature an almond milk base. The company said it spent nearly three years tasting samples and tweaking the recipes prior to launch, churning at least 50 versions of the almond milk base mix so the taste and texture were spot-on. Some versions, the company said, were too thick to freeze or too firm to scoop.

Ben & Jerry’s is owned by Unilever U.S., Englewood Cliffs, N.J. Another Unilever brand, Magnum, recently announced a plant-based introduction featuring a creamy vanilla-flavored base made with coconut oil and pea protein encased in non-dairy Belgian chocolate.
