Step 1: Prepare the Coffee Syrup
- Brew the Coffee: Brew a strong cup of coffee or espresso and let it cool to room temperature.
- Sweeten the Coffee: In a bowl, mix the brewed coffee with the coffee liqueur (if using) and granulated sugar. Stir until the sugar has dissolved. Set aside.
Step 2: Make the Creamy Filling
- Whisk the Egg Yolks and Sugar: In a heatproof bowl, whisk together the egg yolks and granulated sugar until pale and slightly thickened. You can do this with a hand whisk or an electric mixer.
- Heat the Egg Mixture: Set the bowl over a pot of simmering water (double boiler method) and whisk constantly for 5-7 minutes, until the mixture becomes smooth, thick, and slightly increased in volume. It should reach a temperature of 160°F (71°C) to ensure it’s safe to consume. Remove from heat and let it cool slightly.
- Add the Mascarpone: Once the egg mixture has cooled slightly, add the mascarpone cheese. Mix gently until smooth and fully combined.
- Whip the Cream: In a separate bowl, whip the heavy cream and vanilla extract until stiff peaks form. Be careful not to overwhip.
- Fold the Whipped Cream: Gently fold the whipped cream into the mascarpone mixture until smooth and fluffy. This will create the creamy, airy filling for the tiramisu.
Step 3: Assemble the Tiramisu
- Soak the Ladyfingers: Quickly dip each ladyfinger into the coffee syrup. Do not soak them too long, as they will become soggy. You just want to dip them for a second or two, ensuring they absorb some coffee flavor but remain firm.
- Layer the Ladyfingers: Arrange a layer of soaked ladyfingers in the bottom of a 9×13-inch dish or a similar-sized trifle dish. You can also use individual serving glasses or bowls for a more personalized presentation.
- Add the Creamy Filling: Spread half of the mascarpone mixture over the layer of ladyfingers. Use a spatula to smooth it out evenly.
- Repeat Layers: Add a second layer of soaked ladyfingers and top with the remaining mascarpone mixture. Smooth the top layer evenly.
Step 4: Chill the Tiramisu
- Refrigerate: Cover the tiramisu with plastic wrap and refrigerate for at least 4-6 hours, but preferably overnight. This allows the flavors to meld together and the tiramisu to firm up.
Step 5: Serve
- Garnish: Before serving, dust the top of the tiramisu with unsweetened cocoa powder using a fine mesh sieve. You can also sprinkle grated dark chocolate or chocolate shavings on top for an extra touch of indulgence.
- Slice and Enjoy: Slice the tiramisu into squares or serve individual portions with a spoon. Enjoy this creamy, coffee-flavored dessert!
Tips for Success:
- Egg Safety: If you’re concerned about using raw eggs, you can use pasteurized eggs or egg substitute for safety.
- Coffee Intensity: Adjust the strength of the coffee syrup based on how strong you like the coffee flavor in your tiramisu.
- Alternative to Ladyfingers: If you can’t find ladyfingers, you can use sponge cake or pound cake as a substitute. Just make sure they are soft and absorb the coffee syrup well.
- Make-Ahead: Tiramisu actually improves with time, as the flavors have more time to meld together, so it’s perfect for preparing in advance.
Enjoy your Tiramisu—a luscious and creamy dessert that’s perfect for coffee lovers and special occasions!
