Creating Individual Tiramisu can be an enjoyable process. Follow these steps to achieve incredible results:

1. Prepare Coffee: Brew espresso or strong coffee and let it cool to room temperature. Mix in coffee liqueur if using.
2. Whip Egg Yolks: In a mixing bowl, whisk together the egg yolks and granulated sugar until pale and creamy.
3. Add Mascarpone: Gently fold in the mascarpone cheese and vanilla extract into the egg yolk mixture until smooth and well combined.
4. Whip Egg Whites: In another clean bowl, beat the egg whites until stiff peaks form.
5. Combine Mixtures: Carefully fold the whipped egg whites into the mascarpone mixture, ensuring you maintain the airy texture.
6. Dip Ladyfingers: Quickly dip each ladyfinger into the cooled coffee, coating both sides but not soaking them.
7. Layer: In individual serving cups or glasses, place a layer of coffee-dipped ladyfingers at the bottom. Top with a layer of the mascarpone mixture, smoothing it out into an even layer.
8. Repeat Layers: Add another layer of dipped ladyfingers followed by another layer of the mascarpone mixture. Finish with a final layer of mascarpone on top.
9. Chill: Cover the cups with plastic wrap and refrigerate for at least 2-4 hours, ensuring the flavors meld together beautifully.
10. Serve: Before serving, dust the top of each Tiramisu with unsweetened cocoa powder and garnish with chocolate shavings or curls if desired.
