As an avid home baker, I am always seeking recipes that impress without overwhelming, and these individual delights fit the bill perfectly for any occasion, from a sophisticated dinner party to a delightful afternoon tea.

Ingredients:

For the Sponge Cake Base:

2 large eggs, at room temperature, which helps them whip up beautifully.
60g granulated sugar (about 1/4 cup plus 1 tablespoon), for sweetness and structure.
60g all-purpose flour (about 1/2 cup), sifted, to ensure a light and airy texture.
15g unsalted butter (about 1 tablespoon), melted and cooled, for richness.
A pinch of salt, to balance the flavors.
Vegetable oil or butter for greasing the pan.

For the Blackberry Puree & Mousse:

450g fresh or frozen blackberries (about 3 cups), divided. If using frozen, there’s no need to thaw them completely before cooking.
100g granulated sugar (about 1/2 cup), adjustable to the sweetness of your berries.
30ml fresh lemon juice (about 2 tablespoons), to brighten the blackberry flavor.
15g powdered gelatin (about 2 tablespoons or 2 1/2 packets), crucial for the mousse’s set.
90ml cold water (about 6 tablespoons), for blooming the gelatin.
480ml heavy cream (about 2 cups), very cold, for whipping into soft peaks and providing that luxurious mousse texture.
2-3 drops red or purple food coloring (optional), to enhance the vibrant color of your Mini Blackberry Mousse Cakes.

For the Blackberry Mirror Glaze:

150g fresh or frozen blackberries (about 1 cup).
50g granulated sugar (about 1/4 cup).
10ml fresh lemon juice (about 2 teaspoons).
5g powdered gelatin (about 2 teaspoons or 1/2 packet).
30ml cold water (about 2 tablespoons), for blooming the gelatin.
2-3 drops red or purple food coloring (optional, but highly recommended for a vibrant finish).

For Garnish:

Fresh blackberries.
Fresh mint leaves.
A dusting of powdered sugar (optional).

Phase 1: Preparing the Sponge Cake Bases

The foundation of our delightful Mini Blackberry Mousse Cakes is a light and airy sponge cake. We’re aiming for small, thin discs that will serve as the perfect base for our mousse.

Preheat and Prepare: First things first, let’s get our oven ready. Preheat your oven to 175°C (350°F). Line a baking sheet with parchment paper. If you have an 8×8 inch or similar square pan, you can line that too. I often find it easier to bake a thin sheet of sponge and then cut out the circles.
Melt the Butter: Gently melt your 15g of unsalted butter and set it aside to cool slightly. We don’t want to add hot butter to our delicate batter.
Whip the Eggs and Sugar: In a large, clean mixing bowl, combine the 2 large eggs and 60g of granulated sugar. Using an electric mixer, whisk these on high speed for about 7-10 minutes. This step is crucial for achieving a light sponge. The mixture should become very pale, thick, and almost triple in volume. When you lift the whisk, a ribbon of batter should slowly fall back into the bowl and momentarily hold its shape before disappearing.
Fold in Flour: Sift the 60g of all-purpose flour and the pinch of salt directly over the egg mixture in two additions. Using a spatula, gently fold the flour into the egg mixture. Be very careful not to deflate the air you’ve worked so hard to incorporate. Use a delicate motion, cutting down through the center and sweeping up the sides of the bowl.
Incorporate Butter: Take a small portion of your batter (about 1/4 cup) and mix it with the cooled melted butter in a separate small bowl. This step lightens the butter mixture, making it easier to fold into the main batter without deflating it. Then, gently fold this butter mixture back into the main batter until just combined. Again, avoid overmixing.
Bake the Sponge: Pour the batter evenly onto your prepared baking sheet or into your lined square pan. Use an offset spatula to spread it into a thin, even layer. Bake for 10-12 minutes, or until the cake is lightly golden and springs back when gently touched.
Cool and Cut: Once baked, transfer the sponge cake on its parchment paper to a wire rack to cool completely. Once cool, use a 5cm (2-inch) round cookie cutter to cut out about 12-15 small cake discs. These will be the bases for your Mini Blackberry Mousse Cakes. You can always freeze any leftover sponge cake scraps for another use or enjoy them as a chef’s treat!

Phase 2: Crafting the Silky Blackberry Mousse

This is where the magic truly happens! A light, airy, and intensely flavorful blackberry mousse will be the star of our Mini Blackberry Mousse Cakes.

Bloom the Gelatin: In a small bowl, sprinkle the 15g of powdered gelatin over 90ml of cold water. Stir briefly and let it sit for 5-10 minutes. The gelatin will absorb the water and swell, becoming thick and jelly-like. This is called “blooming” and is essential for its proper function.
Prepare Blackberry Puree: In a medium saucepan, combine 300g of the fresh or frozen blackberries (reserving 150g for the glaze), 100g of granulated sugar, and 30ml of lemon juice. Cook over medium heat, stirring occasionally, until the berries break down and release their juices, about 8-10 minutes. Use a potato masher or the back of a spoon to help break them down further.
Strain the Puree: Pour the warm blackberry mixture through a fine-mesh sieve into a clean bowl, pressing firmly on the solids with a spatula to extract as much liquid as possible. Discard the seeds and pulp. This gives us a beautifully smooth blackberry puree, free of any unpleasant bits.
Melt Gelatin into Puree: Add the bloomed gelatin to the warm blackberry puree. Stir until the gelatin is completely dissolved and no granules remain. It’s important that the puree is warm enough to dissolve the gelatin but not boiling hot. If the puree has cooled too much, you can gently warm it again over low heat, stirring constantly, just until the gelatin dissolves.
Cool the Puree: Let the blackberry puree cool down completely to room temperature, or even slightly cooler. You can place the bowl over an ice bath to speed up this process, stirring frequently. It should be cool to the touch, but not set. Adding warm puree to whipped cream will cause it to melt. If using food coloring, stir it into the cooled puree now for an extra pop of color in your Mini Blackberry Mousse Cakes.
Whip the Heavy Cream: In a separate large, very cold bowl (I often chill my bowl and whisk attachments in the freezer for 15 minutes), whip the 480ml of very cold heavy cream using an electric mixer on medium-high speed. Whip until soft peaks form. You want it light and airy, but not stiff.
Fold Mousse Together: Once your blackberry puree is completely cool, gently fold about one-third of the whipped cream into the puree to lighten it. Then, add the remaining whipped cream and carefully fold until no streaks of cream or puree remain and the mixture is uniformly colored and airy. The key here is gentle folding to maintain the airiness of the mousse.

Phase 3: Assembling Your Mini Blackberry Mousse Cakes

Now comes the exciting part – bringing all the components together to form our elegant Mini Blackberry Mousse Cakes!

Prepare Molds: You’ll need individual silicone molds for this, ideally hemisphere molds or small ring molds. If using ring molds, place them on a tray lined with parchment paper or a silicone mat. If you want a perfectly smooth side, you can line the inside of the ring molds with acetate strips.
Pipe or Spoon Mousse: Carefully spoon or pipe the blackberry mousse into your prepared molds, filling them about two-thirds of the way. If using hemisphere molds, fill them almost to the top, leaving a small space for the cake base.
Add Sponge Cake Base: Gently place one of your small sponge cake discs on top of the mousse in each mold. Press lightly so it’s slightly submerged. This will form the base of your Mini Blackberry Mousse Cakes.
Chill Thoroughly: Transfer the tray with the molds to the refrigerator and chill for at least 4-6 hours, or preferably overnight. This chilling time is crucial for the mousse to set properly and allow for easy unmolding. Patience is a virtue here, as a well-set mousse ensures your Mini Blackberry Mousse Cakes hold their beautiful shape.

Phase 4: Creating the Lustrous Blackberry Mirror Glaze

A glossy mirror glaze will add a professional touch and an extra burst of blackberry flavor to our Mini Blackberry Mousse Cakes. It’s surprisingly straightforward to make!

Bloom Gelatin (Again!): In a small bowl, sprinkle the 5g of powdered gelatin over 30ml of cold water. Stir and let it bloom for 5-10 minutes, just as we did before.
Prepare Glaze Puree: In a small saucepan, combine the remaining 150g of fresh or frozen blackberries, 50g of granulated sugar, and 10ml of lemon juice. Cook over medium heat, stirring, until the berries are soft and have released their juices, about 5 minutes.
Strain for Smoothness: Pass the warm berry mixture through a fine-mesh sieve into a clean bowl, pressing firmly to extract all the liquid and leaving behind the seeds and pulp. We want a perfectly smooth glaze for our Mini Blackberry Mousse Cakes.
Melt Gelatin into Glaze: Add the bloomed gelatin to the warm blackberry puree. Stir until the gelatin is completely dissolved. If the puree isn’t warm enough, gently heat it over low heat, stirring constantly, until the gelatin dissolves.
Add Color (Optional): If desired, stir in 2-3 drops of red or purple food coloring to achieve a more intense and appealing color for your mirror glaze.
Cool the Glaze to Pouring Temperature: Let the blackberry glaze cool to about 30-35°C (86-95°F). You can use a thermometer for precision, or test by dipping a clean spoon – it should be cool enough not to melt the mousse immediately but still liquid enough to pour smoothly. If it gets too cold and starts to thicken, you can gently rewarm it over a very low heat or a warm water bath, stirring constantly, until it reaches the correct consistency.

Phase 5: Finishing and Garnishing Your Mini Blackberry Mousse Cakes

The final steps involve unmolding, glazing, and decorating your stunning Mini Blackberry Mousse Cakes. This is where they truly transform!

Unmold the Mousse Cakes: Once your mousse cakes are completely chilled and set, carefully unmold them. If using silicone molds, gently peel back the silicone from the edges. If using ring molds, use a small torch or warm cloth around the edges for a few seconds to help release them, then push up from the bottom. Place the unmolded mousse cakes on a wire rack set over a baking sheet (to catch excess glaze).
Glaze the Cakes: Ensure your mirror glaze is at the correct pouring temperature (30-35°C / 86-95°F). Slowly pour the glaze over each chilled Mini Blackberry Mousse Cake, starting from the center and working your way outwards, allowing it to coat the entire surface and drip down the sides. The glaze should form a thin, even, and shiny layer. Repeat for all cakes.
Let Glaze Set: Allow the glazed Mini Blackberry Mousse Cakes to sit on the wire rack for about 10-15 minutes to allow the excess glaze to drip off and the glaze to set slightly.
Transfer to Serving Platter: Carefully transfer the glazed Mini Blackberry Mousse Cakes from the wire rack to a serving platter or individual dessert plates using a thin spatula.
Garnish and Serve: Garnish each of your beautiful Mini Blackberry Mousse Cakes with a fresh blackberry and a small mint leaf. If you like, a very light dusting of powdered sugar can add a delicate touch, but the mirror glaze is usually enough.
Serve Chilled: These Mini Blackberry Mousse Cakes are best served chilled. They make a perfect elegant dessert for any occasion! Enjoy the fruit of your labor!

Elevate Your Dessert Experience with Creative Servings

Now, while these Mini Blackberry Mousse Cakes are undeniably magnificent on their own, a little creativity in presentation or a slight tweak in flavor can elevate them even further. For a classic touch, a dusting of powdered sugar or a sprig of fresh mint makes for a beautiful garnish that enhances their natural appeal. Imagine them adorned with a few extra fresh blackberries, perhaps even some raspberries for a delightful color contrast that pops against the rich purple. If you’re feeling adventurous, consider pairing them with a light raspberry coulis drizzled artfully around the plate – the tartness of the raspberry complements the blackberry mousse beautifully, adding another layer of berry goodness. A very thin dark chocolate drizzle could also add a touch of sophisticated bitterness, cutting through the sweetness and providing a wonderful textural contrast that truly elevates the overall profile.

For those who love a bit of crunch, a sprinkle of toasted slivered almonds, finely chopped pistachios, or even some candied pecans could provide a wonderful textural counterpoint to the silky mousse, adding an exciting dimension to each bite. Want to play with flavors? While blackberries are the undeniable star here, you could experiment with other berry purees for the mousse layer – think rich raspberry, sweet strawberry, or even a mixed berry blend for a multi-faceted flavor profile. A tiny splash of Crème de Cassis or Chambord added to the blackberry puree before folding it into the mousse could introduce a sophisticated, boozy undertone perfect for adult palates and special occasions. For a citrusy twist, a very fine grating of lemon or orange zest over the top before serving adds a bright, fresh aroma and flavor that awakens the senses and provides a lovely counterpoint to the fruit. You could also consider serving them alongside a small dollop of lightly sweetened vanilla bean whipped cream or a quenelle of tangy crème fraîche to offer an alternative creamy element that guests can enjoy. For a truly unique presentation, consider setting them on a small bed of finely crushed shortbread cookies or ginger snaps for an extra layer of textural delight at the base, creating a deconstructed pie-like experience that is both fun and delicious. The possibilities truly are endless, and I encourage you to let your culinary imagination run wild!
