Subway to give low-cal milkshakes a spin in Halo Top partnership

Subway says it’s “shaking things up” with a new way to stay cool this summer.

The sandwich chain announced on Monday that it partnered with the light dessert company Halo Top Creamery to bring low-calorie milkshakes to 1,000 of its U.S. stores for a limited time only.

Starting July 22, the day after National Ice Cream Day, participating restaurants will have shakes in three classic flavors: vanilla bean, chocolate and strawberry. The 16-ounce shakes each have at least 20 grams of protein, according to Halo Top.

If you want a “hand-spun” dessert, the 350-calories-or-less snack will be available in the following six test markets through Sept. 4: Colorado Springs, Colorado; Hartford, Connecticut; Longview and Tyler, Texas; Salt Lake City, Utah; Toledo, Ohio; and West Palm Beach, Florida.

“We are passionate about creating delicious new menu items for our guests that can’t be found anywhere else,” said Len Van Popering, Subway’s chief brand and innovation officer, in a statement. ”We share Halo Top’s values that taste does not need to be sacrificed to create better-for-you options.”

Halo Top started the trend of high-protein, lower calorie ice cream in 2012. Pints have 280 to 360 calories and pack 20 grams of protein.

Subway is the first brand to feature Halo Top in milkshake form.

The initial rollout is just a test, so you may see the Halo Top desserts pop up in more stores in the future.

”We are excited to bring this popular brand to our guests in a never-before-seen way that we know they will love,” Van Popering said.
