Step‑by‑Step Instructions for No-Bake Blackberry Tart
Step 1: Prepare the Crust
Begin by crushing the Oreo cookies into fine crumbs using a food processor or by placing them in a sealed plastic bag and rolling over them with a rolling pin. Melt the vegan butter and mix it with the crumbs until it resembles wet sand. Press this mixture firmly into the bottom of a 9-inch tart pan and place it in the freezer for 15 minutes to firm up the crust.
Step 2: Make the Mousse Filling
In a blender, combine the fresh blackberries and blueberries until smooth, creating a vibrant puree. If you prefer a seedless filling for your No-Bake Blackberry Tart, strain the mixture through a fine mesh sieve to remove any seeds. Set the berry puree aside as you gather your other ingredients for the mousse.
Step 3: Combine Ingredients
In a large mixing bowl, blend the strained berry puree with non-dairy cream cheese, sugar, and vanilla extract using an electric mixer until the mixture is creamy and well combined. This will create a luscious base for your mousse filling, ensuring every bite of the No-Bake Blackberry Tart is sweet and satisfying.
Step 4: Whip the Cream
In a separate bowl, whip the non-dairy cream with an electric mixer until stiff peaks form. This usually takes about 2–3 minutes. The whipped cream should be fluffy and light, adding a wonderful airy texture to the mousse. Gently fold the whipped cream into the berry mixture to maintain its lightness and enhance the overall texture of the filling.
Step 5: Activate Agar
To activate the agar powder, dissolve it in a measured amount of non-dairy milk. Heat the mixture over low heat, stirring continuously until it reaches a gentle boil. Allow it to cool slightly for about 5 minutes, ensuring it’s ready to incorporate into your mousse without solidifying prematurely. This step is essential for achieving the right consistency in your No-Bake Blackberry Tart.
Step 6: Fill and Chill
Carefully fold the cooled agar mixture into the creamy berry filling, taking care not to deflate the airy whipped cream. Once fully combined, pour the luscious mousse into the prepared Oreo crust, smoothing the top with a spatula. Cover the tart with plastic wrap and refrigerate for at least 4 hours or overnight to allow it to set perfectly.
Step 7: Serve
When ready to serve your No-Bake Blackberry Tart, gently remove it from the tart pan. Garnish the top with additional fresh blackberries or blueberries for a burst of color and flavor. Cut into slices and serve chilled for a refreshing dessert that will leave your guests delighted and asking for seconds!
Make Ahead Options
These Easy Vegan No-Bake Blackberry Mousse Tarts are perfect for busy cooks looking to save time! You can prepare the Oreo crust and mousse filling up to 24 hours in advance. Simply mix the crushed cookies with melted vegan butter, press into the tart pan, and chill in the freezer for 15 minutes. For the mousse, blend the berries and combine with the other ingredients, then refrigerate until you’re ready to assemble. To maintain quality, cover the tart tightly with plastic wrap to prevent it from absorbing odors in the fridge. When ready to serve, let the tart sit at room temperature for about 10 minutes before slicing. You’ll enjoy all the delicious flavors with minimal effort!
Expert Tips for No-Bake Blackberry Tart
-
Agar Awareness: Ensure agar powder is completely dissolved in the non-dairy milk for a smooth texture; otherwise, you may end up with an unappealing graininess.

Easy Vegan No-Bake Blackberry Mousse Tart Recipe FAQs
What kind of blackberries should I use for the tart?
Absolutely! Opt for ripe, fresh blackberries that are plump and shiny. Avoid those with dark spots or mold, which may indicate overripeness. For the best flavor, choose berries that are in-season, ideally during late spring to early summer.
How long can I store the No-Bake Blackberry Tart?
You can store your No-Bake Blackberry Tart in the fridge for up to 3 days. To keep it fresh, wrap it tightly in plastic wrap or place it in an airtight container – this helps maintain its creamy texture and delicious flavor!
Can I freeze the No-Bake Blackberry Tart for later?

What should I do if my mousse doesn’t set properly?
If your mousse doesn’t set, it could be that the agar wasn’t fully dissolved. To troubleshoot, gently reheat the mousse mixture over low heat, stirring constantly, until it’s fully warmed but not boiling. Then, let it cool slightly before folding in more whipped cream and placing it back in the tart crust. Remember to chill it afterward for it to set correctly!
Are there any allergies I should consider with this recipe?
Very! Always check the labels for potential allergens in your substitutes, especially for gluten and nuts. If you use store-bought oreo cookies, ensure they’re gluten-free if your guests are sensitive. Also, consider other dietary needs, like nut allergies—using non-dairy milk alternatives can help accommodate those.
Can I prepare the tart in advance?
Absolutely! This No-Bake Blackberry Tart is perfect for making ahead. In fact, it’s best when chilled overnight, as this allows the flavors to blend beautifully. Just cover it well and store it in the fridge until you’re ready to serve—it’s a delightful treat that exceeds expectations!
