Ingredients You’ll Need

These simple yet essential ingredients each play a vital role in building the fabulous taste, texture, and color of the tart. From the crunchy cookie crust to the creamy berry filling, everything comes together seamlessly.

  • Oreo Cookies (28 cookies, 320g): Using cookies with cream filling provides a rich, chocolaty base that crumbles perfectly for the crust.
  • Vegan Butter (1/3 cup, 80g, melted): This binds the cookie crumbs into a firm crust, adding a subtle buttery flavor that’s essential for texture.
  • Blackberries & Blueberries (8 oz, 225g): These fresh berries give vibrant color, juicy sweetness, and natural tartness that brighten the mousse.
  • Non-Dairy Cream Cheese (1 cup, 225g): Adds creamy richness and smooth texture while keeping the tart entirely dairy-free.
  • Sugar (1/3 cup, 75g): Sweetens the berry filling just enough to balance the fruit’s natural tanginess.
  • Vanilla Extract (2 tsp): Enhances the overall flavor with warm, aromatic notes.
  • Non-Dairy Whipping Cream (1 cup, 240ml, chilled): Provides lightness and volume to the filling, making it fluffy and airy.
  • Non-Dairy Milk (1/4 cup, 60ml): Used to dissolve agar powder and blend ingredients smoothly.
  • 100% Agar Powder (1 tsp): A vegan-friendly thickening agent that helps the mousse set perfectly without any oven time.

How to Make No-Bake Blackberry Tart Recipe

Step 1: Prepare the Cookie Crust

The foundation of this tart is a rich, crunchy cookie crust that’s surprisingly fuss-free. Simply crush the Oreo cookies (filling and all) in a blender or food processor into fine crumbs. This filling adds a slight creaminess and binds well. Then, mix the crushed crumbs with melted vegan butter until they’re evenly moistened. Press this mixture firmly onto the bottom and sides of a 9 or 9.5-inch tart pan with a removable base. To help it hold shape, chill the crust in the freezer for 15 minutes or in the fridge for 30 minutes while making the mousse filling.

Step 2: Blend the Berry Purée

Next up, it’s time to transform the fresh blackberries and blueberries into a smooth, luscious purée. Blend the berries until smooth, then, if you prefer a silky texture, strain the mixture through a fine mesh sieve to remove seeds. Return the purée to the blender and add non-dairy cream cheese, sugar, and vanilla extract, blending everything until it’s velvety and well combined. This blend is where the tart gets its beautiful color and fruity character.

Step 3: Whip the Non-Dairy Cream

To achieve that light and airy mousse, whip the chilled non-dairy whipping cream using a handheld mixer until stiff peaks form. It’s important to keep it cold to ensure the best volume and texture. Set aside the whipped cream, refrigerated, while preparing the agar solution.

Step 4: Prepare the Agar Mixture

In a small saucepan, stir the agar powder into the non-dairy milk and bring it to a boil, cooking for about 2 minutes or according to the package instructions. This activation step is essential for agar to function as a thickening agent. Once done, remove from heat and allow it to cool slightly. This warm liquid will gently hold the mousse together once combined.

Step 5: Combine and Chill the Mousse

Fold the slightly cooled agar mixture carefully into the berry purée. Then gently fold in the whipped cream, stirring just until everything is combined without deflating the cream. Pour this airy, colorful mousse into the prepared crust, smoothing the top for a polished finish. Place the tart in the refrigerator for at least 4 hours, but overnight chilling is even better, allowing the mousse to set perfectly and flavors to meld.

Step 6: Serve and Enjoy

When the mousse has fully firmed, gently release the tart from the pan’s removable bottom. This is your moment to shine by adding fresh fruits or other toppings of your choice to make the tart look irresistible. Serve chilled for a refreshing, creamy dessert that everyone will rave about.

The middle layer is thick, smooth, and pastel purple in color, making up most of the tart. The top layer is thin and darker purple, decorated with clusters of fresh blackberries and blueberries along with small purple flowers on its surface. The large tart, also on a white round stand, is visible in the background with a missing slice. Around the plate, there are scattered blackberries, purple flowers with green leaves, halves of red plums, and a vintage dark metal fork placed beside the tart slice.

Garnishes

To make your tart irresistibly beautiful and extra tasty, consider topping it with fresh berries like blackberries, blueberries, or even sliced strawberries. A light dusting of powdered sugar or a drizzle of vegan chocolate sauce adds a delightful finishing touch. Fresh mint leaves also provide a burst of color and aroma that pairs perfectly with the berries.

Side Dishes

This tart shines on its own but pairs wonderfully with a scoop of vegan vanilla ice cream or a dollop of coconut whipped cream for those extra indulgent moments. For brunch or afternoon tea, consider serving alongside lightly brewed herbal tea or freshly brewed coffee to balance the tart’s sweetness.

Creative Ways to Present

If you’re feeling adventurous, try layering small jars or glasses with the cookie crumb crust, mousse filling, and berry topping for stylish individual servings. You can also create a berry compote reduction as a vibrant sauce drizzle around plated slices to elevate presentation for special occasions.

Make Ahead and Storage

Storing Leftovers

Any leftover tart should be kept covered in the refrigerator to maintain freshness and firmness. It will keep wonderfully for up to three days without losing its texture or flavor. Make sure to store it in an airtight container or cover the tart pan tightly with plastic wrap.

Freezing

This tart can be frozen for longer storage. Wrap the chilled tart tightly in plastic wrap and then in aluminum foil to prevent freezer burn. Thaw it overnight in the refrigerator before serving. The texture will remain creamy and the flavors intact thanks to the no-bake mousse base.

Reheating

Since the No-Bake Blackberry Tart Recipe is best enjoyed chilled, reheating is not recommended. If you prefer it slightly less cold, simply let it sit at room temperature for 10 to 15 minutes before serving to soften the mousse slightly without losing its structure.

FAQs

Can I use different cookies for the crust?

Absolutely! While Oreos work wonderfully due to their cream filling, you can substitute with any crunchy cookies that you like. Just ensure they are finely crushed so the crust binds well with the melted butter.

Is agar powder necessary for this recipe?

Agar powder is key if you want a vegan, firm mousse that holds its shape without baking. It acts similarly to gelatin. If you aren’t vegan, you can use gelatin powder as a substitute, following similar preparation steps.

Can I make this tart gluten-free?

Yes! Simply swap Oreo cookies for gluten-free sandwich cookies with cream filling to keep the crust safe for gluten sensitivity or allergies without compromising flavor.

How do I prevent the filling from being too runny?

Make sure to properly dissolve and cook the agar powder as instructed. Also, folding the whipped cream gently preserves the mousse’s airiness and consistency, helping it set firmly after chilling.

Can I prepare this tart in advance for parties?

Definitely! This no-bake tart is an excellent make-ahead dessert. Prepare it the day before your event to allow ample chilling time, and garnish just before serving for the freshest look and taste.

This No-Bake Blackberry Tart Recipe is truly a joyful creation you’ll keep coming back to.

  • 2 tsp vanilla extract

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.

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.
