Here’s how to create your own Eggless Pistachio Tiramisu with ease:

1. Prepare the Pistachios: Finely grind the unsalted pistachios in a food processor. Reserve a small amount for garnishing later.
2. Mix the Mascarpone: In a large bowl, combine mascarpone cheese, powdered sugar, and vanilla extract. Use a hand whisk or electric mixer until smooth and creamy.
3. Whip the Cream: In another bowl, whip the heavy cream until soft peaks form. Gradually fold this whipped cream into the mascarpone mixture. Do this gently to maintain the light and airy texture.
4. Combine Flavors: Add the finely ground pistachios to the mascarpone mixture and fold them in until evenly distributed.
5. Prepare the Coffee Mixture: Mix the brewed coffee and coffee liqueur (if using) in a shallow dish. This will be used for soaking the ladyfingers.
6. Assembly: Briefly dip each ladyfinger into the coffee mixture, ensuring they absorb enough coffee without becoming soggy. Layer them in a rectangular serving dish.
7. First Layer of Cream: Spread half of the pistachio mascarpone mixture over the first layer of soaked ladyfingers, smoothing it out evenly.
8. Repeat the Layers: Add another layer of dipped ladyfingers, followed by the remaining mascarpone mixture.
9. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours, or overnight to achieve a firmer texture.
10. Serve: Once chilled, dust the top with cocoa powder and garnish with the reserved pistachios before slicing and serving.
