Creating a delicious White Chocolate Raspberry Tiramisu is simple when you follow these steps:

1. Melt White Chocolate: In a microwave-safe bowl, melt the chopped white chocolate in 30-second intervals, stirring until smooth. Set aside to cool slightly.
2. Whip Cream: In a separate bowl, whip the heavy cream until soft peaks form.
3. Combine Mixtures: In a large bowl, mix the mascarpone cheese, powdered sugar, and vanilla extract. Gently fold in the melted white chocolate until well combined.
4. Fold in Whipped Cream: Carefully fold the whipped cream into the mascarpone mixture until fully incorporated, taking care not to deflate the whipped cream.
5. Prepare Coffee: Brew strong coffee and allow it to cool. You may add a splash of coffee liqueur for an extra kick.
6. Dip Ladyfingers: Quickly dip each ladyfinger into the cooled coffee, ensuring they are soaked but not soggy.
7. Layer Ingredients: In a serving dish, arrange a layer of dipped ladyfingers at the bottom. Spread half of the white chocolate mixture over the ladyfingers, followed by half of the fresh raspberries.
8. Repeat Layers: Add another layer of coffee-dipped ladyfingers, followed by the remaining white chocolate mixture and raspberries.
9. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to allow the flavors to meld.
10. Serve: Before serving, dust the top with cocoa powder and garnish with additional raspberries for an elegant touch.
