Description

This Creamy No-Bake Blackberry Mousse is a light, airy, and elegant dessert made with real blackberries, whipped cream, and a hint of vanilla. It’s easy to prepare, requires no baking, and delivers a stunning presentation—perfect for spring and summer gatherings or special occasions.


Ingredients

  • 2 cups fresh or frozen blackberries (thawed if frozen)
  • 1/3 cup granulated sugar (adjust to taste)
  • 1 tablespoon lemon juice
  • 1 packet (about 2 1/4 tsp) unflavored gelatin or agar-agar (for vegetarian option)
  • 3 tablespoons cold water
  • 1 cup heavy cream
  • 1 teaspoon vanilla extract
  • Optional toppings:
  • Whipped cream
  • Fresh blackberries
  • Mint leaves
  • White chocolate shavings

Instructions

  1. In a medium saucepan, combine blackberries, sugar, and lemon juice. Cook over medium heat for 8–10 minutes, until the berries are soft and syrupy.

  2. Blend the mixture until smooth, then strain through a fine mesh sieve to remove seeds. Let it cool slightly.

  3. In a small bowl, sprinkle gelatin over cold water. Let bloom for 5 minutes, then gently heat to dissolve. Stir the dissolved gelatin into the cooled blackberry puree.

  4. In a separate bowl, whip the heavy cream with vanilla extract until soft peaks form.

  5. Gently fold the blackberry mixture into the whipped cream until fully combined and smooth.

  6. Spoon the mousse into individual serving glasses. Refrigerate for 2–3 hours, or until set.

  7. Garnish with optional toppings before serving.


Notes

  • For a mixed berry twist, add raspberries or blueberries.
  • Blackberry liqueur adds an adult-friendly depth of flavor.
  • For a layered parfait, alternate mousse with crushed cookies or sponge cake.
  • Agar-agar can be used for a vegetarian version—follow package instructions for preparation.
  • Best served chilled and fresh—freezing is not recommended.
