Follow these steps to create your incredible tiramisu:

1. Prepare the Cream Mixture: In a medium saucepan, combine egg yolks and sugar. Whisk until well blended. Add milk and cook over low heat, stirring constantly, until it thickens (about 5-7 minutes). Allow it to cool.

2. Make the Whipped Cream: In a large bowl, beat the chilled heavy cream until soft peaks form. Be careful not to over-whip.

3. Combine Mixtures: Once the egg yolk mixture has cooled, fold in the mascarpone cheese, mixing until smooth. Then, gently fold in the whipped cream until combined.

4. Soak the Ladyfingers: In a shallow dish, mix the cooled espresso with coffee liqueur. Quickly dip each ladyfinger into the mixture, ensuring they get soaked but not overly soggy.

5. Layer the Ingredients: In a 9×9-inch dish, lay half of the soaked ladyfingers at the bottom. Spread half of the mascarpone mixture over them.

6. Repeat Layering: Repeat the process with another layer of soaked ladyfingers followed by the remaining mascarpone mixture.

7. Chill: Cover the dish with plastic wrap or aluminum foil and refrigerate for at least 4 hours, or overnight for best results.

8. Dust with Cocoa Powder: Before serving, dust the top generously with cocoa powder using a fine sieve for an elegant finish.

Creating tiramisu is straightforward once you follow these steps. You’ll be amazed at how easily you can produce such a delightful dish!
