Ice cream sandwiches have been a beloved American treat since the early 1900s, originally made with soft homemade cookies or wafers. They became popular at fairs and later as packaged snacks, symbolizing a simple, portable indulgence for both kids and adults.

Subway introduced its soft, bakery‑style cookies in the early 2000s, and their consistent texture and sweet flavor made them an easy, store‑bought alternative to baking cookies from scratch, perfect for quick ice cream sandwich creations.

They are often served at summer barbecues, birthday parties, and casual gatherings because they are easy to make, handheld, and can be customized with different cookie and ice‑cream flavors.

Beyond classic chocolate chip cookies, some regions favor brownies, peanut butter cookies, or even corn‑flake coated wafers. In the South, pecan pie ice cream between shortbread cookies is a favorite, while the West Coast loves matcha or oat‑milk ice cream with vegan cookies.

Using pre‑made Subway cookies saves time and guarantees a soft, uniform cookie, while the Peanut Butter S'mores ice cream adds a rich, salty‑sweet flavor that isn’t typical of classic vanilla or chocolate ice cream sandwiches.

It embodies the American love for convenience, indulgence, and remixing familiar flavors—combining a popular fast‑food bakery item with a premium ice‑cream brand to create a nostalgic yet modern treat.

Traditionally, a soft cookie or wafer and a vanilla or chocolate ice cream are used. Acceptable substitutes include any flavored ice cream (like Peanut Butter S'mores) and any soft cookie (such as Subway’s double chocolate, chocolate chip, or raspberry cheesecake).

The biggest errors are letting the ice cream melt too much before cutting, pressing the cookies too hard and breaking them, and not allowing enough freezing time for the sandwiches to set.

A brief softening makes the ice cream pliable enough to cut cleanly while keeping it firm enough to hold its shape, preventing the pucks from becoming mushy during assembly.

Yes, assemble the sandwiches and keep them sealed in an airtight container in the freezer. They will stay fresh for up to two weeks; bring them to room temperature for a few minutes before serving for optimal texture.
