Tiramisu, a classic Italian dessert, contains a moderate amount of caffeine due to the use of espresso in its preparation. The exact caffeine content can vary depending on the amount of espresso used and the size of the serving. On average, a typical serving of tiramisu can contain around 50-75 milligrams of caffeine, similar to a small cup of coffee. This amount is enough to provide a subtle energy boost without causing excessive jitters or other adverse effects.
