Mini Blackberry Mousse Cakes Ingredients
For the Crust
- Chocolate Sandwich Cookies – The base structure for the crust, providing flavor and crunch; use gluten-free varieties if needed.
- Unsalted Butter – Binds the cookie crumbs together to create a sturdy crust; can substitute with coconut oil for a dairy-free option.

- Sugar – Sweetens the mousse; can substitute with honey or agave for a different sweetness.
- Water – Assists in cooking the blackberries and helps blend into a purée.
- Lemon Juice – Adds acidity to balance sweetness; can replace with lime juice for a unique tang.
- Gelatin – Provides stability and structure to the mousse, necessary for setting; substitute with agar for a vegan version.
- Heavy Cream – Creates the airy texture of the mousse when whipped; use coconut cream as a dairy-free alternative.
- Vanilla Extract – Enhances flavor depth in the mousse.
For the Glaze
- White Chocolate Chips – The base for the smooth glaze, adding richness; chop a white chocolate bar as a substitute.
- Heavy Cream (for glaze) – Creates a silky texture and adds richness to the glaze.
These Mini Blackberry Mousse Cakes are not just a dessert; they are a delightful experience that will transport you to a world of elegance and indulgence. Enjoy crafting them!
Step‑by‑Step Instructions for Mini Blackberry Mousse Cakes
Step 1: Prepare the Crust
In a mixing bowl, combine crushed chocolate sandwich cookies with melted unsalted butter. Stir until the mixture resembles wet sand, then press it firmly into silicone or ring molds, creating an even layer. Place the molds in the freezer for about 15 minutes, allowing the crust to firm up and hold its shape nicely.
Step 2: Cook the Blackberries
In a saucepan, combine fresh or frozen blackberries with sugar and water over medium heat. Stir occasionally until the blackberries break down, approximately 5-7 minutes. Once cooked, blend the mixture until smooth and strain it through a fine mesh sieve to remove any seeds, resulting in a silky blackberry purée.
Step 3: Incorporate the Gelatin
In a small bowl, bloom the gelatin by sprinkling it over lemon juice and letting it sit for a few minutes. Then, gently warm the gelatin mixture until dissolved, before mixing it into the warm blackberry purée. Allow this mixture to cool to room temperature while you prepare the next component of your Mini Blackberry Mousse Cakes.
Step 4: Whip the Cream
In a separate bowl, whip the heavy cream until soft peaks form, using a whisk or electric mixer on medium speed. This process takes about 3-5 minutes. Once ready, gently fold in the vanilla extract and cooled blackberry-gelatin mixture, taking care to maintain the airy texture for a light and fluffy mousse.
Step 5: Assemble the Mousse Cakes
After the crusts have set, pour the luscious blackberry mousse over the chilled cookie bases in the molds. Use a spatula to smooth the tops evenly. Place the assembled Mini Blackberry Mousse Cakes in the refrigerator for at least 4 hours, or until the mousse is fully set and has a firm texture.
Step 6: Prepare the White Glaze
To create the silky white chocolate glaze, heat a small saucepan over low heat and pour in the heavy cream. Once hot, pour it over white chocolate chips in a heatproof bowl and let sit for a few minutes. Stir the mixture gently until completely smooth and glossy, allowing it to cool slightly before glazing the mousse cakes.
Step 7: Glaze and Decorate
Once the mousse has set, carefully remove the cakes from the molds and place them on a plate. Drizzle the cooled white glaze over each cake, allowing it to cascade down the sides. For a final touch, sprinkle fresh blackberries and edible flowers on top just before serving, adding a beautiful pop of color to your Mini Blackberry Mousse Cakes.

Storage Tips for Mini Blackberry Mousse Cakes

Mini Blackberry Mousse Cakes Recipe FAQs
What should I look for when selecting blackberries?
Absolutely! When selecting blackberries, look for plump, shiny berries that are deep purple-black in color. Avoid any with dark spots or mold, as they may be overripe. If using frozen blackberries, ensure they are well-sealed to prevent freezer burn and thaw them properly before cooking.
How should I store leftover mousse cakes?
Very! To store leftover Mini Blackberry Mousse Cakes, keep them in an airtight container in the refrigerator. They will stay fresh for up to 3 days. For optimal flavor and texture, try to consume them within 24 hours of preparation.
Can I freeze the mousse cakes?
Definitely! While it’s best not to freeze the fully glazed mousse cakes due to potential texture changes, you can freeze the unglazed mousse for up to 2 months. To do this, prepare the mousse, pour it into the crust, but hold off on glazing. Cover tightly and place in the freezer. When ready to enjoy, thaw in the fridge overnight before glazing and serving.
What if my mousse doesn’t set properly?
If your mousse isn’t setting properly, the most common issue may relate to the gelatin. Make sure that it was fully bloomed and dissolved before mixing it into the blackberry purée. If the mixture was too warm when you added the gelatin, it might not firm up correctly. A good tip is to create a double batch or double-check the packaged gelatin instructions for best results!
Are Mini Blackberry Mousse Cakes suitable for those with dietary restrictions?
Of course! These Mini Blackberry Mousse Cakes can easily cater to various dietary needs. To make them vegan, substitute gelatin with agar-agar, and use plant-based cream and chocolates. If you have nut allergies or are gluten-sensitive, make sure to select appropriate brands for your chocolate cookies and creams. Always check ingredient labels to ensure they meet your dietary preferences!
How long will the mousse last after serving?
I recommend that these delightful treats be consumed within 24 hours of preparation for the best flavor and freshness. However, if stored properly in the refrigerator, they can remain tasty for up to 3 days. Just ensure to keep them covered to avoid absorbing any fridge odors!
