Follow these simple steps to create your exquisite No-Bake Blackberry Mousse:

1. Prepare Blackberries: Wash the fresh blackberries under cold water. Pat them dry with a paper towel.
2. Blend Blackberries: In a blender, add the blackberries, granulated sugar, and lemon juice. Blend until smooth and well combined.
3. Strain Mixture: Pour the blended mixture through a fine sieve into a bowl, using a spoon to push it through. Discard any seeds.
4. Whip Cream: In a separate bowl, whip the heavy cream until stiff peaks form. This should take about 2-3 minutes.
5. Prepare Cream Cheese: In another bowl, beat the softened cream cheese until smooth and creamy.
6. Mix Cream Cheese and Sugar: Gradually add in the powdered sugar and continue to beat until fully combined. Add the vanilla extract and mix again until incorporated.
7. Combine Mixtures: Gently fold the blackberry puree into the cream cheese mixture until well combined.
8. Add Whipped Cream: Carefully fold in the whipped cream, ensuring a light and airy texture is maintained.
9. Spoon into Cups: Spoon the mousse into individual serving cups or a large bowl. Smooth the tops with a spatula.
10. Chill: Cover with plastic wrap and refrigerate for at least 2 hours, or until set.
11. Garnish: Before serving, top with fresh berries and mint leaves for an elegant look.
