In a blender or food processor, blend the raspberries, lemon juice, and sugar. Set aside.
In a medium-sized mixing bowl, beat the heavy cream and powdered sugar until soft peaks form (it took a few minutes).
Gently fold the raspberry mixture into the whipped cream. You can partially fold it in so that it has raspberry streaks or you can mix it completely so that it's a pink dessert - either way is great.
Serve immediately or keep in the fridge for a few hours (this is best served the day of!).
If desired, top each serving with fresh berries.
