Is there caffeine in the chocolate part of an ice cream sandwich?

It's unlikely.

* Chocolate ice cream: Most chocolate ice creams do not contain caffeine. They are typically made with cocoa powder, sugar, milk, and cream, none of which have caffeine.

* Chocolate wafers: While some chocolate wafers used in ice cream sandwiches might have a small amount of caffeine, it's not a common ingredient. The caffeine would likely come from cocoa beans, which can contain trace amounts of caffeine.

To be sure, check the ingredient list on the specific ice cream sandwich you're interested in. If you're sensitive to caffeine, err on the side of caution and assume there is no caffeine present.
