In a small bowl, with an electric mixer, beat the cream until stiff peaks form. Be careful to not over mix or it'll turn into butter!
1/4 cup (60 ml) whipping cream
In a separate medium bowl, using the same beaters, mix together the cream cheese and melted white chocolate. Add the Greek yogurt and mix until well combined and then add the mashed raspberries and stir.
4 ounces (112 grams) full-fat cream cheese, 1/3 cup (56 grams) white chocolate, 1/2 cup (120 grams) plain Greek yogurt, 1/2 cup (60 grams) fresh or frozen raspberries
Fold in all but a tablespoon of cream (you’ll use that tablespoon to put on top of the mousse). Try to keep the mousse as light as possible. Spoon the mousse into two serving glasses and serve, or chill until serving, up to eight hours. Right after you make it, this mousse is thick and creamy and very similar to a no-bake cheesecake filling. After chilling in the fridge for a while, it softens and becomes more mousse-like.
Top with the leftover cream and garnish with raspberries, if desired.
