Creating your White Chocolate Raspberry Tiramisu is a straightforward process if you follow these easy steps:

1. Melt the White Chocolate: In a microwave-safe bowl, melt the white chocolate chips in 20-second intervals, stirring in between until smooth. Let it cool slightly.

2. Prepare the Cream Mixture: In a mixing bowl, combine the mascarpone cheese and powdered sugar. Mix until smooth and creamy.

3. Whip the Cream: In another bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the mascarpone mixture.

4. Combine with White Chocolate: Once the white chocolate has cooled, gently fold it into the mascarpone and whipped cream mixture until well combined.

5. Prepare Coffee Mixture: In a shallow dish, combine the cooled brewed coffee with the coffee liqueur (if using).

6. Assemble the Layers: Quickly dip each ladyfinger into the coffee mixture, ensuring they soak but do not become soggy. Arrange a layer of soaked ladyfingers in the bottom of a serving dish.

7. Add Cream Layer: Spread half of the white chocolate cream mixture over the ladyfingers. Sprinkle half of the fresh raspberries on top.

8. Repeat Layers: Add another layer of soaked ladyfingers, followed by the remaining white chocolate cream. Top with the remaining raspberries.

9. Chill the Tiramisu: Cover the dish with plastic wrap and refrigerate for at least 4 hours, or overnight for the best flavor.

10. Serve: Before serving, dust the top with cocoa powder and garnish with additional raspberries for an elegant touch.

By following these steps, you will create a stunning White Chocolate Raspberry Tiramisu that is sure to impress!
