Ice cream

If there’s coffee or chocolate in your ice cream, expect the scoop to deliver a small jolt. Many popular brands have coffee flavors that contain between 30 and 45 milligrams of caffeine per half cup, which is about the same as a can of Coke. Chocolate ice cream has much less, however; a half cup of Breyer’s All Natural Chocolate ice cream has only 3 milligrams, according to a Consumer Reports analysis.
