Step‑by‑Step Instructions for Easy Vegan No-Bake Blackberry Mousse Tart
Step 1: Prepare the Crust
Begin by crushing about 24 Oreo cookies in a food processor until they transform into fine crumbs. Melt 6 tablespoons of vegan butter and mix it with the cookie crumbs in a bowl until well combined. Press this mixture firmly into the bottom and up the sides of a 9-inch tart pan to form an even crust. Chill the crust in the freezer for 15 minutes while you prepare the filling.
Step 2: Make Mousse Filling
In the same food processor, blend 1 cup of fresh blackberries and 1 cup of blueberries until smooth, adding a little water if necessary. For a silky texture, you may strain the berry puree through a fine mesh sieve to remove seeds. In a mixing bowl, combine the berry puree with 8 ounces of non-dairy cream cheese, ½ cup of sugar, and 1 teaspoon of vanilla extract; mix until well blended and creamy.
Step 3: Whip Cream
In another bowl, using an electric mixer, whip 1 cup of non-dairy whipping cream on medium-high speed until stiff peaks form, which should take about 3-5 minutes. This will add the necessary lightness to your mousse filling. Once whipped, set the cream aside while you prepare the agar mixture, making sure it stays cool.
Step 4: Combine Mixtures
In a small saucepan, dissolve 1 tablespoon of agar powder in ½ cup of non-dairy milk over medium heat, whisking continuously until it comes to a gentle boil. Remove from heat and allow it to cool slightly for about 3 minutes. Gently fold this cooled agar mixture into the berry mixture, ensuring everything is well integrated, before carefully folding in the whipped cream to maintain the fluffy texture.
Step 5: Fill and Chill
Once your mousse filling is ready, pour it into the prepared Oreo crust, smoothing the top with a spatula for an even surface. Cover the tart with plastic wrap and place it in the refrigerator. Allow it to chill for at least 4 hours, or ideally overnight, to set properly and develop richer flavors.
Step 6: Serve
After the tart has chilled, carefully remove it from the tart pan. Garnish the top with extra blackberries or a sprinkle of fresh berries for a pop of color. Slice your Easy Vegan No-Bake Blackberry Tart and serve chilled to enjoy a refreshing dessert that everyone will love!

Easy Vegan No-Bake Blackberry Mousse Tart Recipe FAQs
What kind of blackberries should I use?
Absolutely! Look for fresh, plump blackberries that have a rich, deep color. Avoid any that have dark spots all over, which might indicate overripeness. You can also feel free to swap them out for other berries like strawberries or raspberries for a delightful twist!
How do I store leftovers?
To keep your no-bake blackberry tart fresh, store it covered in the refrigerator for up to 3 days. Make sure it’s well-wrapped to prevent it from absorbing any odors from the fridge. When ready to enjoy, just slice and serve chilled for the best taste!
Can I freeze this tart?
Yes, you can! To freeze your tart, wrap individual slices tightly in plastic wrap and place them in a freezer-friendly container. You can enjoy these slices for up to 2 months! When you’re ready to indulge, simply thaw the slices in the refrigerator for a few hours, ensuring they return to their delicious, creamy perfection.
What if my mousse doesn’t set properly?
No worries! If your mousse is too runny, it may be due to agar not being fully dissolved. To fix this, reheat the mixture gently and whisk until smooth, then let it cool slightly before adding it back to the mousse. If you find yourself without agar, consider using a different thickening agent like arrowroot powder or cornstarch, but note that those may require additional cooking.

Very much so! This Easy Vegan No-Bake Blackberry Tart is completely plant-based and gluten-free when using gluten-free cookies. However, keep an eye on ingredient labels for those with specific allergies, particularly with non-dairy ingredients. If you have pets, it’s best to keep them away from this dessert, as some ingredients can be harmful to animals.
Can I make this tart ahead of time?
You definitely can! In fact, it’s best to let the tart chill overnight for the flavors to meld beautifully. Just cover it well before refrigerating to ensure it doesn’t pick up any unwanted odors. Your guests will be thrilled at the wonderful taste you’ve prepared!
