Making Pistachio Tiramisu is a straightforward process if you follow these easy steps:

1. Prepare the Pistachios: Place the shelled pistachios in a food processor and pulse until finely ground. Reserve about 2 tablespoons for garnishing later.
2. Combine the Cream: In a large mixing bowl, add the heavy whipping cream, granulated sugar, vanilla extract, and almond extract. Whip until soft peaks form.
3. Add Mascarpone: Gently fold in the mascarpone cheese until fully blended and smooth. Be careful not to deflate the mixture.
4. Mix Coffee: In a shallow dish, combine the cooled brewed coffee with 2 tablespoons of the ground pistachios.
5. Dip Ladyfingers: Quickly dip each ladyfinger into the coffee mixture, ensuring they are soaked but not soggy. Lay them in a single layer at the bottom of a serving dish or square pan.
6. Layer the Cream: Spread half of the pistachio mascarpone mixture over the soaked ladyfingers, smoothing it out evenly.
7. Repeat Layers: Add another layer of dipped ladyfingers on top of the mascarpone, followed by the remaining pistachio mixture.
8. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight for best flavor.
9. Serve: Before serving, dust the top with cocoa powder and sprinkle the reserved pistachios for an elegant touch.
