The Simple Answer: Yes, They Have Caffeine
Desserts that incorporate espresso, instant espresso powder, or brewed coffee will contain caffeine. The caffeine content does not get cooked out or evaporate during the baking process. The amount per serving, however, is a function of the total caffeine in the dish divided by the number of servings. For most common recipes, this means a moderate amount of caffeine in each slice or scoop. It is important to distinguish between using liquid espresso and espresso powder, as this can affect the total caffeine of the recipe. Espresso powder is essentially concentrated coffee, so a small amount can contribute a significant dose of caffeine to a dish.
Key Factors Influencing Caffeine Levels
Several variables determine how much caffeine ends up in your dessert. The total amount isn't the only thing to consider; the distribution throughout the dish matters, as does the inherent strength of the coffee itself.
- Type of Espresso Product: Using liquid espresso from a shot versus concentrated espresso powder will change the total caffeine content. Espresso powder is often more potent by weight.
- Bean Type and Roast: Robusta beans naturally contain more caffeine than Arabica beans. Similarly, light roasts tend to have more caffeine by weight than dark roasts.
- Quantity Used in Recipe: The more espresso or espresso powder a recipe calls for, the higher the total caffeine in the final product. For instance, a recipe using a double shot of espresso will have more caffeine than one using a single shot.
- Serving Size: A large slice of tiramisu will contain more caffeine than a smaller one, as the total amount is distributed across fewer portions. A dish with a high total caffeine content can have a relatively low amount per serving if it's meant to feed a crowd.
Caffeine in Popular Espresso Desserts
Certain desserts are well-known for their espresso component. Here is an overview of some common coffee-infused treats and their typical caffeine ranges per serving.
Tiramisu
This classic Italian dessert is famous for its coffee-soaked ladyfingers. The total caffeine per batch varies based on the espresso used. According to one analysis, a batch of tiramisu could contain approximately 292.5mg of caffeine total, which, when divided into 8-12 servings, results in 24.4 to 36.6mg per piece. Some home recipes may use stronger or weaker coffee, changing this range. A typical slice of tiramisu contains about half the caffeine of a regular cup of coffee, but it is enough to affect sensitive individuals.
Affogato
An affogato is a simple yet elegant dessert featuring a scoop of ice cream drowned in a hot shot of espresso. Since it's made to order, the caffeine content is easy to calculate based on the espresso shot used. A single shot of espresso contains about 63mg of caffeine on average, while a double shot contains about 126mg. The final caffeine is the sum of the shots poured over the ice cream, making it a more potent, direct dose than a baked good.
Mocha Desserts
Mocha-flavored treats, such as cakes, brownies, and cheesecakes, combine espresso or coffee with chocolate. Chocolate itself contains a small amount of caffeine and other stimulants like theobromine, adding to the total. For example, a recipe for mocha fudge cheesecake might call for espresso powder to enhance the chocolate flavor, providing a moderate caffeine boost. The final amount will depend on the recipe's ingredient proportions.
Comparison: Caffeine in Common Desserts
To put the caffeine content of espresso desserts into perspective, here is a comparison based on data from a Serious Eats analysis. Note that these figures are based on specific recipes and can vary significantly.
| Dessert | Caffeinated Ingredient | Caffeine Per Serving | Source |
|---|---|---|---|
| Tiramisu | 5 oz espresso | 24.4–36.6 mg | |
| Fudge Brownies | 1 tsp instant espresso | 19.6 mg | |
| Flourless Chocolate Cake | 1 tsp instant espresso | 35.5 mg | |
| Devil's Food Cake | 12 oz brewed coffee | 30.9 mg |
Decaf Options and Alternatives
For those sensitive to caffeine, options exist to enjoy the rich, bold flavor of coffee without the stimulating effects. Many dessert recipes can be easily adapted to use decaffeinated ingredients.
- Use Decaf Espresso or Powder: Standard decaf espresso contains a negligible amount of caffeine (3-15mg per shot), making it a safe substitute. Decaf instant espresso powder is also widely available for baking.
- Flavor Extracts: Coffee extract can provide a concentrated coffee flavor without any caffeine. This works well for items like frostings, icings, or creams that don't rely on the liquid volume of brewed coffee.
- Alternative Flavorings: Other ingredients like roasted chicory root or malted milk powder can provide a similar depth of flavor without the caffeine content. These can be particularly effective in chocolate desserts where coffee is used to enhance the cocoa notes.
Conclusion
In summary, any dessert that calls for espresso, espresso powder, or brewed coffee will contain a measurable amount of caffeine. While the overall caffeine load per serving is typically far less than a full cup of coffee, it is not zero. For popular choices like tiramisu or affogato, a serving can still deliver a noticeable dose, which is an important consideration for individuals sensitive to caffeine, children, or those watching their evening intake. The good news is that with readily available decaf ingredients and alternative flavorings, it is entirely possible to enjoy the rich taste of coffee in your favorite sweet treats without the added buzz.
