Gourmet ice cream sandwiches are so hot (so cold?) right now. The latest eatery to introduce its high-end version of the childhood classic is Café Dupont. The restaurant is teaming up with The Styleliner, a former potato chip truck retrofitted into clothing boutique on wheels. Giving new meaning to the term “good taste,” the vehicle will sell both couture and gold flake-topped s’more ice cream sandwiches curbside on select days (May 23, 30, June 6, 13 from 5-8 p.m.).

The $9 off-the-menu ice cream sandwiches—made with Valrhona dark chocolate ice cream and bruleed white chocolate marshmallows on house-made graham crackers—will also be available upon request at Cafe Dupont every Wednesday through Friday from 5-8 p.m. throughout the summer. They debut tomorrow.

“A lot of those items that have been forgotten a little bit are coming back,” says Cafe Dupont chef Silvan Kramer, an ice cream lover who grew up in Switzerland, where there were no ice cream trucks. “People are looking for something that reminds them of their childhoods.”

Bar Dupont isn’t the only spot serving up ice cream sandwich nostalgia. Sugar Magnolia, the sister bakery to Ripple in Cleveland Park, has several rotating varieties including a strawberry ice cream sandwich with lavender sponge cake and chocolate ice cream with peanut butter cookies—all $3.50 each.

Poste Moderne Brasserie is also making house-made ice cream sandwiches using seasonal infusions from its garden. And let’s not forget the long, skinny chocolate cookie hazelnut ice cream version from José Andrés‘ flautas food truck, Pepe. Know of any others? Add ’em in the comments.

UPDATE: Poste no longer has ice cream sandwiches on the menu, although it is serving a rhubarb-stuffed shortbread cookie topped with strawberry ice cream.

Some other noteworthy examples: Firefly has a peanut butter ice cream “sandwich” made with flourless chocolate cake, bananas foster sauce, peanut brittle, and sea salt. A commenter also points to a classic chocolate cookie vanilla ice cream sandwich at Central. It’s $9.
