Step‑by‑Step Instructions for Mini Blackberry Mousse Cakes
Step 1: Prepare the Crust
Begin by crushing chocolate sandwich cookies into fine crumbs using a food processor. Melt unsalted butter in a microwave-safe bowl, then combine it with the cookie crumbs until well blended. Firmly press this mixture into the bottom of silicone or ring molds to create a sturdy crust. Place the molds in the freezer for 15 minutes to set the crust properly.
Step 2: Make the Blackberry Mousse
In a saucepan over medium heat, combine fresh or frozen blackberries, sugar, and water. Cook until the berries are broken down and bubbly, which should take about 5-7 minutes. Once cooked, blend the mixture into a smooth purée and strain it through a fine mesh sieve to remove seeds. Bloom gelatin in lemon juice, then warm it slightly; stir into the blackberry purée. Fold in vanilla extract and whipped cream until the mixture is light and smooth.
Step 3: Assemble Mousse Cakes
Once the chocolate crust has set, pour the blackberry mousse over it in the molds, distributing evenly. Gently tap the molds on the counter to release any air bubbles. Cover with plastic wrap and refrigerate for at least 4 hours, or until the mousse is firm and set.
Step 4: Prepare the Glaze
To create a luscious glaze, heat heavy cream in a small saucepan until it simmers, then pour it over white chocolate chips in a bowl. Let it sit for a minute, then stir until fully melted and smooth. Allow the glaze to cool slightly before it’s too hot to pour – this helps preserve the mousse structure when covering.
Step 5: Garnish
After the mousse cakes have set, carefully unmold them onto serving plates. Pour the slightly cooled glaze over each cake, ensuring a smooth and even coating. For a beautiful finishing touch, top each Mini Blackberry Mousse Cake with a fresh blackberry and an edible flower just before serving.

Mini Blackberry Mousse Cakes Recipe FAQs
How do I select ripe blackberries for this recipe?
Absolutely! Choose fresh blackberries that are plump, firm, and have a deep, vibrant color. They should smell sweet and fragrant; avoid those with dark spots all over, as these may be overripe or spoiled. If using frozen blackberries, ensure they’re well-packed and check the expiration date.
What’s the best way to store leftover Mini Blackberry Mousse Cakes?
Very simple! Store your leftover Mini Blackberry Mousse Cakes in an airtight container in the refrigerator for up to 3 days. This keeps them fresh, so they taste as delightful as when you first made them. Just remember to cover the cakes nicely to avoid absorbing other odors from the fridge.
Can I freeze Mini Blackberry Mousse Cakes?
Yes, you can! However, it’s best to freeze the mousse cakes before adding the glaze. Wrap the unglazed cakes tightly in plastic wrap, then place them in a freezer-safe container. They will keep for up to 2 weeks. When you’re ready to enjoy them, simply transfer the cakes to the fridge to thaw overnight, and then glaze them right before serving.
What if my mousse isn’t setting properly?
If your mousse isn’t setting, it could be due to the gelatin not being fully dissolved. Always ensure you bloom the gelatin thoroughly in lemon juice before adding it to your blackberry purée. If all else fails, try chilling the mousse longer in the refrigerator; patience can be key! Alternatively, consider adding a touch more gelatin if you want a firmer consistency.
Are Mini Blackberry Mousse Cakes suitable for vegans?
Yes! You can easily make a vegan version of these delectable cakes by substituting gelatin with agar-agar. To do this, follow the packet instructions for blooming and dissolving the agar. Additionally, swap out heavy cream with coconut cream and use vegan white chocolate for the glaze. Voila! You have a beautifully indulgent vegan dessert!
