Ingredients

Scale

Crust

  • 28 Oreo Cookies (320g, or other cookies with cream filling)
  • 1/3 cup vegan butter (80g, melted)

Filling

  • 8 oz Blackberries & Blueberries (225g)
  • 1 cup non-dairy cream cheese (225g, or drained yogurt)
  • 1/3 cup sugar (75g)
  • 2 tsp vanilla extract
  • 1 cup non-dairy whipping cream (240ml, chilled, or coconut cream)
  • 1/4 cup non-dairy milk (60ml)
  • 1 tsp 100% agar powder (or gelatin powder if non-vegan)

Instructions

  1. Prepare Cookie Crust: Add cookies with cream filling into a blender or food processor and crush until finely ground. Transfer crumbs to a medium bowl, add melted vegan butter, and mix until crumbs are evenly moistened. Press the mixture onto the bottom and up the sides of a 9 or 9.5-inch (23/24cm) tart pan with a removable bottom. Place in the freezer for 15 minutes or in the fridge for 30 minutes to firm up while preparing the filling.
  2. Make Berry Puree: Add the blackberries and blueberries into a blender and blend until smooth. Optionally, strain the berry puree through a mesh sieve to remove seeds and then return to the blender.
  3. Prepare Berry Mixture: To the berry puree, add non-dairy cream cheese, sugar, and vanilla extract, and blend until smooth. Set this mixture aside.
  4. Whip Non-Dairy Cream: In a mixing bowl, whip the cold non-dairy whipping cream using a handheld mixer until stiff peaks form. Refrigerate until ready to use.
  5. Activate Agar Powder: In a small saucepan, stir the agar powder into the non-dairy milk. Bring the mixture to a boil and cook for about 2 minutes according to package instructions. Remove from heat and let cool slightly, stirring occasionally. (If using gelatin powder, this step can be skipped; gelatin should be dissolved following its own instructions.)
  6. Combine Filling Components: Gently fold the cooled agar mixture into the berry puree mixture, then gently fold in the whipped non-dairy cream. Stir just until fully combined to maintain the mousse texture.
  7. Fill and Chill Tart: Pour the mousse filling into the prepared tart crust, smoothing out the top evenly. Refrigerate for at least 4 hours, preferably overnight, to allow the tart to fully firm up.
  8. Serve: Once set, remove the tart by gently pressing against the removable bottom of the pan. Decorate with additional fresh fruits or toppings of your choice and serve chilled.
  9. Enjoy Your No-Bake Blackberry Tart: Slice and savor this refreshing, creamy dessert that’s perfect for any occasion.

Notes

  • If using gelatin powder instead of agar-agar, dissolve gelatin in non-dairy milk according to package directions, typically soaking in cold milk before heating gently to dissolve. Skip the boiling step used for agar.
  • For a smoother filling texture, straining the berry puree to remove seeds is recommended but optional.
  • This tart is best served chilled and should be stored in the refrigerator.
  • You can substitute vegan butter with regular butter if not vegan.
  • Feel free to garnish with fresh berries, mint leaves, or a dusting of powdered sugar for added presentation.
