In a bowl, drop the egg yolk and sugar. Whisk for 5 minutes or until it turns thick and fluffy. The color will change to pale yellow. If you have an electric mixer, it will make things a lot easier.
Add the mascarpone cheese and White Chocolate Caramel Cappuccino. Whisk it for a minute to incorporate it all together.
Using a separate bowl and a separate whisker, whisk the egg white until you get stiff peaks. It should take about 3 minutes with the electric mixer.
Slowly pour the whipped egg white into the mascarpone cappuccino mixture and fold it carefully. Then, pour it in a container or multiple small containers and freeze it overnight.
Top it with some fresh raspberries and shaved white chocolate just before serving.
