Mini Blackberry Mousse Cakes Ingredients
For the Crust
• Chocolate Sandwich Cookies – These form the delicious base crust; feel free to substitute with vanilla cookies for a milder flavor.
• Unsalted Butter – Binds cookie crumbs together; margarine or coconut oil can be used for a dairy-free option.
For the Mousse
• Fresh or Frozen Blackberries – The main flavor for the mousse; make sure to purée thoroughly for a smooth consistency.
• Sugar – Sweetens the blackberry mixture; adjust to taste or swap for honey for a natural sweetener.
• Water – Helps break down the berries during cooking, achieving the perfect purée.
• Lemon Juice – Enhances berry flavor and adds acidity; lime juice makes a great alternative if desired.
• Gelatin – Provides necessary structure to the mousse; use agar-agar to keep it vegan-friendly.
• Heavy Cream – Whipped to soft peaks for a light, airy mousse texture; coconut cream serves as a dairy-free alternative.
• Vanilla Extract – Adds depth; feel free to omit for a more fruit-forward profile.
For the Glaze
• White Chocolate Chips – Adds sweetness and creaminess to the glaze; dairy-free white chocolate is a good substitute for vegan versions.
• Heavy Cream (for glaze) – Provides that silky texture; alternative cream can be used for dairy-free options.

Step‑by‑Step Instructions for Mini Blackberry Mousse Cakes
Step 1: Prepare Crust
Begin by crushing the chocolate sandwich cookies into fine crumbs. In a mixing bowl, combine the crumbs with melted unsalted butter until well blended. Firmly press this mixture into the bottom of silicone or ring molds, ensuring an even layer. Freeze the crust for 15 minutes, allowing it to harden, creating the perfect base for your Mini Blackberry Mousse Cakes.
Step 2: Cook Blackberries
In a saucepan over medium heat, add the fresh or frozen blackberries along with sugar and water. Cook the mixture until the blackberries break down and release their juices, about 5-7 minutes. Once softened, transfer the mixture to a blender and purée until smooth, then strain through a fine mesh sieve to remove the seeds, keeping your mousse silky and refined.
Step 3: Bloom Gelatin
In a small bowl, soak the gelatin in lemon juice for about 5 minutes until it softens. Meanwhile, gently warm the blackberry purée on low heat until just lukewarm. Stir the bloomed gelatin into the warm berry mixture until fully dissolved. Allow the blackberry-Gelatin mixture to cool to room temperature, which will ensure your mousse sets beautifully in the next steps.
Step 4: Make Mousse
In a large mixing bowl, whip the heavy cream to soft peaks, ensuring it’s light and airy. Once the blackberry and gelatin mixture has cooled, gently fold in the whipped cream until fully incorporated and no streaks remain. This delightful blend of flavors creates the luscious filling for your Mini Blackberry Mousse Cakes, ready to be layered over the prepared crust.
Step 5: Assemble Cakes
Carefully pour the blackberry mousse over the chilled cookie crusts in the molds, filling them evenly. Use a spatula to smooth out the tops as needed. Place the assembled cakes in the refrigerator to chill for at least 4 hours or until fully set. This step allows the mousse to reach that perfect, melt-in-your-mouth consistency that everyone will love.
Step 6: Prepare Glaze
In a small saucepan, heat the heavy cream over low heat until it starts to simmer. Remove it from the heat and pour it over the white chocolate chips in a bowl. Let it sit for a minute before stirring until smooth and glossy. Allow the glaze to cool slightly so it thickens slightly without solidifying; this ensures it coats beautifully when poured over the mousse.
Step 7: Finalize Dessert
Once the mousse has set, pour the warm white chocolate glaze over the chilled Mini Blackberry Mousse Cakes. Gently tilt the molds to help the glaze spread evenly across the tops. Finish by garnishing each cake with fresh blackberries and a few edible flowers for a stunning presentation. Serve chilled, and enjoy the elegance of this delightful no-bake dessert!

Expert Tips for Mini Blackberry Mousse Cakes
- Gelatin Magic: Ensure gelatin is fully dissolved in the lemon juice before adding to the mousse to prevent lumps and ensure a smooth texture in your Mini Blackberry Mousse Cakes.
- Chill Time: Allow the mousse to set in the refrigerator for a minimum of 4 hours. Rushing this step might result in a runny texture instead of the desired fluffiness.
- Mold Matters: Use silicone molds for easy unmolding. They provide a clean release and showcase your elegant cakes beautifully.
- Perfect Glaze: Let the glaze cool slightly before pouring it over the cakes. If it’s too hot, it can melt the mousse layer underneath, ruining that lovely presentation.

Mini Blackberry Mousse Cakes Recipe FAQs
How do I know if my blackberries are ripe?
Absolutely! Ripe blackberries should be plump and firm, with a glossy appearance. Look for deep black color, without any signs of dark spots all over, which can indicate overripeness. If they’re a bit red or mushy, it’s best to choose another batch.
Can I store Mini Blackberry Mousse Cakes?
Certainly! You can store the cakes in an airtight container in the refrigerator for up to 3 days. This helps maintain their freshness and the distinct texture of the mousse. Just be cautious not to freeze them once glazed, as this can alter the mousse’s delightful consistency.
What’s the best way to freeze Mini Blackberry Mousse Cakes?
Great question! If you need to freeze them, do so before applying the glaze. Wrap each unglazed mousse cake tightly in plastic wrap, then place them in a freezer-safe container. They can be stored this way for up to 1 month. When ready to enjoy, thaw them overnight in the refrigerator for perfect results.
What if my mousse doesn’t set properly?
Very! If your mousse doesn’t set, it’s likely because the gelatin didn’t bloom properly or wasn’t dissolved completely. Make sure to soak the gelatin in lemon juice for about 5 minutes and gently warm the blackberry mixture to ensure the gelatin integrates seamlessly. For next time, you can also check the cooling temperature of the mixture before combining it with the whipped cream.
Are Mini Blackberry Mousse Cakes suitable for vegetarians or vegans?
Absolutely! These cakes are vegetarian-friendly, and for vegan adaptations, simply substitute gelatin with agar-agar. Use coconut cream instead of heavy cream, and ensure your white chocolate is dairy-free. This way, everyone can enjoy these exquisite mousse cakes without a hitch!
How can I ensure my glaze is perfect every time?
Fantastic inquiry! Allow your heavy cream to warm just until simmering before pouring it over the white chocolate chips. Let it sit for a minute to soften and then gently stir until smooth. Ensure it cools slightly before pouring over the mousse—if too hot, it may melt the delicate layers below. Enjoy creating those stunning glazes!
