Crafting the Perfect Chocolate Almond Cake Base

The foundation of our stunning chocolate caramel mousse cake is a tender and flavorful chocolate almond cake. This base provides a wonderful contrast to the creamy mousses and ganache, adding structure and a delightful nutty note. Achieving the perfect texture and flavor for this cake requires careful attention to detail.

For the complete, detailed recipe with exact measurements, please refer to the recipe card located further below.

1. **Preheat Your Oven:** Begin by preheating your oven to 180ºC (approximately 350ºF) for a conventional oven. This ensures your oven is at the correct temperature for even baking from the moment your cake goes in.
2. **Prepare Your Pan:** Take a 16cm (approximately 6-inch) silicone mold or a standard cake tin. If using a cake tin, line the bottom with parchment paper to prevent sticking and make removal easier. For a silicone mold, a light greasing can also be beneficial, though often not strictly necessary.
3. **Sieve Dry Ingredients:** In a medium bowl, carefully sieve together the all-purpose flour, baking powder, a pinch of salt, and rich cocoa powder. Sieving is a crucial step as it removes any lumps, aerates the dry ingredients, and ensures they are evenly distributed, leading to a lighter, more uniform cake texture. Give them a quick whisk to combine thoroughly and set this mixture aside.
4. **Cream Marzipan, Butter, and Sugar:** In a separate, larger mixing bowl, roughly grate the marzipan. This helps it integrate better into the mixture. Add the room temperature butter and granulated sugar to the grated marzipan. Using a hand mixer or a stand mixer fitted with the paddle attachment, beat these ingredients together on medium speed for 1-2 minutes. Continue mixing until the mixture becomes wonderfully light, pale, and fluffy. This creaming process incorporates air, which is vital for a tender cake.
5. **Incorporate Eggs:** Add the eggs one at a time, mixing on low speed after each addition until just combined. Overmixing at this stage can develop too much gluten, resulting in a tougher cake. Ensure each egg is fully incorporated before adding the next.
6. **Fold in Dry Ingredients:** Gradually add the previously sieved flour mixture to the wet ingredients. Mix on low speed until the dry ingredients are just combined. Again, avoid overmixing. The goal is to bring the batter together without overworking the gluten.
7. **Add Milk:** Finally, with the mixer still on low speed, pour in the milk. Mix until it is just incorporated into the batter. The milk adds moisture and helps create a smooth consistency.
8. **Bake the Cake:** Pour the prepared cake batter evenly into your silicone mold or lined cake tin. Bake for 22-25 minutes. If you are using a metal cake tin, it may bake slightly faster than a silicone mold, so start checking for doneness a few minutes earlier. The cake is ready when a wooden skewer inserted into the center comes out clean.
9. **Cooling Process:** Once baked, remove the cake from the oven and let it cool on a wire rack for a few minutes until it’s cool enough to handle. Then, carefully remove it from the silicone mold or cake tin and place it back on the wire rack to cool completely. Allowing it to cool fully is essential before the next steps.
10. **Prepare for Assembly:** Once the cake has completely cooled, gently place it back into the same (clean) 16 cm silicone mold. Wrap a cake collar (acetate strip) around the inside edge of the mold, extending above the cake. This collar will help with the height of your finished mousse cake and make it significantly easier to remove the delicate dessert from the mold later. Your chocolate almond cake base is now ready for the next delicious component: the caramelized white chocolate ganache.

Crafting the Luscious Caramelized White Chocolate Ganache

The caramelized white chocolate ganache is truly the star of this mousse cake, infusing it with a rich, buttery caramel flavor that sets it apart. The process of caramelizing white chocolate transforms its natural sweetness into a more complex, nutty caramel profile. This layer will sit directly on top of your chocolate almond cake base, providing a wonderful textural and flavor contrast.

1. **Melt the Chocolate:** Begin by semi-melting your caramelized white chocolate. You can do this gently over a bain-marie (double boiler) or in a microwave. If using a microwave, heat in short bursts (15-20 seconds) and stir well after each interval to prevent burning. You want it mostly melted but still with a few small lumps, which will fully melt when the hot cream is added.
2. **Heat Heavy Cream and Glucose Syrup:** In a small saucepan, combine the heavy cream and glucose syrup. Place the pot over medium heat and warm the mixture gently, stirring occasionally, just until it starts to bubble around the edges of the pot. Do not let it boil vigorously, as this can reduce the cream too much. The glucose syrup helps to create a smoother, more stable ganache and prevents crystallization.
3. **Emulsify the Ganache:** Pour the hot heavy cream mixture over the semi-melted caramelized white chocolate in three separate additions. After each addition, use a rubber spatula to gently stir the mixture from the center outwards. This technique, known as emulsification, helps create a smooth, homogenous, and stable ganache without introducing too much air. Continue stirring until the ganache is completely smooth and glossy.
4. **Assemble the Ganache Layer:** Carefully place your cooled chocolate almond cake, which should already be nestled in the 16 cm silicone mold with its cake collar, back into its position. Pour the warm caramelized white chocolate ganache evenly over the cake. Use the back of a spoon or an offset spatula to spread it out smoothly to the edges. This layer will firm up as it chills.
5. **Chill for Setting:** Transfer the mold with the cake and ganache into the freezer. Allow it to freeze for a minimum of 3 hours. This crucial chilling time ensures the ganache is firm enough to support the subsequent mousse layer and allows for clean assembly.

Creating the Velvety Milk Chocolate Mousse

A light and airy milk chocolate mousse forms the heart of this triple chocolate cake. Its creamy texture and delicate chocolate flavor perfectly complement the richness of the almond cake and the caramelized ganache. This section requires careful temperature control and gentle handling to achieve that signature melt-in-your-mouth consistency.

1. **Bloom the Gelatin:** Place the gelatin sheets in a bowl of cold water. Let them sit and soften (bloom) for about 5-10 minutes. This process rehydrates the gelatin, making it ready to dissolve smoothly into the warm liquid.
2. **Prepare Greek Yogurt:** While the gelatin blooms, weigh out your Greek yogurt (preferably 10% fat for richness). Let it sit on the kitchen counter at room temperature. Bringing the yogurt to room temperature prevents the chocolate mixture from seizing when combined.
3. **Heat Cream & Dissolve Gelatin:** In a small saucepan, heat 75g of the total 250g heavy cream over medium heat until it just begins to boil. Immediately remove the pot from the heat. Squeeze any excess water from the bloomed gelatin sheets and add them to the hot cream. Stir continuously with a whisk until the gelatin has completely dissolved into the cream, ensuring no lumps remain.
4. **Combine Chocolate and Cream:** Pour the hot cream-gelatin mixture over the milk chocolate (which should be chopped into small pieces for even melting). Let it sit for about a minute to allow the chocolate to soften. Then, using a spatula, gently fold the mixture together from the middle, slowly incorporating the melted chocolate into the cream until it is cohesive and smooth. This creates a rich chocolate ganache base for the mousse.
5. **Integrate with Greek Yogurt:** Add the milk chocolate mixture into the room temperature Greek yogurt in three separate additions. After each addition, gently fold the two mixtures together until slowly combined. This gradual incorporation helps to temper the yogurt and prevents any separation, resulting in a smooth, unified mixture.
6. **Whip Remaining Heavy Cream:** In a clean, chilled bowl, whip the remaining heavy cream (175g) until it forms soft peaks. Be careful not to over-whip it, as this can make the mousse grainy. Soft peaks mean the cream holds its shape but is still light and airy.
7. **Fold in Whipped Cream:** With a rubber spatula, gently fold the whipped cream into the milk chocolate-yogurt mixture in three parts. Use a light, lifting motion to preserve the air in the whipped cream, ensuring your mousse remains light and airy. Continue folding until the mixture is smooth, homogenous, and beautifully combined.
8. **Prepare Mousse Mold:** Take your 18cm (approximately 7-inch) silicone mold. Place a small cutting board or tray underneath it; this will make it much easier to transfer the filled mold to the freezer later. Line the inside of the silicone mold with a cake collar, ensuring it extends above the mold’s edge. This is crucial because your finished cake will be taller than the mold itself. Pour the prepared milk chocolate mousse into the mold.
9. **Assemble Mousse Cake:** Retrieve the cake base (chocolate almond cake with caramelized white chocolate ganache) from the freezer. Carefully remove the cake collar from around the base. Gently invert the frozen cake base so that the caramelized white chocolate ganache layer faces downwards. Carefully center and press this inverted cake base into the milk chocolate mousse in the 18cm mold. The ganache should be resting on the mousse.
10. **Freeze for Setting:** Gently lift the entire mousse cake (still in its mold with the board underneath) and transfer it to the freezer. Allow it to freeze for a minimum of 6 hours, or preferably overnight. This long freezing time is essential for the mousse to set completely, ensuring a stable structure and clean cuts later on.

Achieving the Perfect Cacao Mirror Glaze

The mirror glaze is the crowning glory of this chocolate caramel mousse cake, providing a stunning, glossy finish that makes it look like a professional patisserie creation. This step requires precision and attention to temperature to achieve that flawless, reflective surface. Don’t be intimidated; with careful execution, you can achieve a truly spectacular result.

1. **Bloom the Gelatin:** As before, place the gelatin sheets in a bowl of cold water to bloom for about 5-10 minutes. This rehydration is key for the glaze’s texture.
2. **Sift Cocoa Powder:** Sift the cocoa powder over a separate bowl. Sieving prevents lumps and ensures a smooth glaze. Set aside.
3. **Prepare Syrup Base:** In a small saucepan, combine the water, granulated sugar, and condensed milk. Stir them together over medium heat until the sugar dissolves and the mixture comes to a rolling boil. Once boiling, immediately remove the pot from the heat.
4. **Dissolve Gelatin:** Squeeze out any excess water from the bloomed gelatin sheets and add them to the hot syrup mixture. Stir continuously until the gelatin is completely dissolved.
5. **Combine with Cocoa Powder:** Hold the bowl with the sifted cocoa powder at an angle. Slowly pour the hot liquid mixture down the edge of the bowl. This technique helps to minimize the creation of air bubbles, which are the enemy of a perfectly smooth mirror glaze. With a rubber spatula, gently stir the cocoa powder and liquid together until the mixture is cohesive and uniform.
6. **Blend for Smoothness:** For an extra-smooth, perfectly emulsified glaze, use an immersion blender (hand blender). Blend the glaze until it is completely smooth, being careful not to lift the blender head out of the liquid, which would incorporate air. Blend at a slight angle to minimize bubbles further.
7. **Strain and Cool:** Pour the mirror glaze into a jug, holding the jug at an angle as you pour to, again, avoid creating additional bubbles. If you have a fine-mesh sieve, you can strain the glaze at this point to ensure ultimate smoothness. Cover the surface of the glaze directly with a piece of cling film (plastic wrap), pressing it down so it touches the entire surface. This prevents a skin from forming. Allow the glaze to cool to a temperature between 33-34ºC (approximately 91-93ºF). This precise temperature is critical for the glaze to adhere beautifully and evenly to the frozen cake without being too thin or too thick.
8. **Prepare Glazing Station:** While the glaze cools, prepare your glazing station. Line a baking tray with a piece of cling film or parchment paper. Place a sturdy cup or a small overturned bowl in the center of the prepared tray. This will serve as a stand for your frozen cake, allowing excess glaze to drip off cleanly.
9. **Glaze the Cake:** Once the mirror glaze has reached the ideal temperature (33-34ºC), take your mousse cake out of the freezer. Carefully remove it from its silicone mold and place it directly onto the cup positioned on your prepared tray. The cake must be frozen solid for the glaze to set instantly and create that coveted mirror finish.
10. **Pour the Glaze:** Slowly and steadily pour the mirror glaze over the entire frozen cake, starting from the center and working your way outwards, ensuring every surface is coated. Let the excess glaze drip off completely into the tray below. This process should be done swiftly.
11. **Final Touches and Defrosting:** Once the glaze has set (which happens quickly on a frozen cake), use a small, sharp knife or offset spatula to carefully remove any mirror glaze droplets that might be hanging off the bottom edge of the cake. Using two offset spatulas, gently lift the glazed cake off the cup and transfer it to your chosen serving dish or cake stand. For an extra touch of elegance, lightly sprinkle the top with edible gold dust for decoration.
12. **Defrost Before Serving:** Place the finished mousse cake in the refrigerator to defrost for 3-4 hours. This allows the mousse layers to soften to their ideal creamy consistency, ensuring every bite is perfect.

Storage Tips for Your Mousse Cake

To preserve the exquisite taste and beautiful presentation of this chocolate and caramel mousse cake, proper storage is key. Store any leftover cake in an airtight container in the refrigerator. This helps maintain its freshness, prevent it from drying out, and protect its delicate flavors. For the best flavor and texture, it is recommended to enjoy this gourmet dessert within a few days of preparation. If you need to store it longer, it can be kept frozen (unglazed) for up to a month, then defrosted and glazed when ready to serve.

Instructions

 

CHOCOLATE ALMOND CAKE

• Preheat the oven to 180ºC conventional oven.
• Prepare a 16cm silicone mold or cake tin with parchment paper in the bottom.
• Sieve together the flour, baking powder, salt, and cocoa powder and mix it together and set it aside.
• Roughly grate the marzipan and add it into a bowl with the butter and granulated sugar. With a hand mixer or stand mixer, mix the ingredients together for 1-2 min, on medium speed. Until nice and fluffy.
• Add the eggs one a time and mix them in on low speed until combined.
• Add the flour and mix as well on low speed until combined.
• Continue on low speed and lastly add the milk and mix it in until just combined.
• Pour the batter into your silicone mold or prepared cake tin and bake for 22-25 min. Are you baking in a metal tin, check a few minutes earlier as it can bake faster.
• Let it cool down on a cooling rack. Once it has cooled down to touch, take it out of the silicone mold and let it completely cool down on a cooling rack.
• Once completely cooled down, place it back into the same (clean) silicone mold with a cake collar wrapped around it. This will make it easier to remove the cake from the silicone mold. Now you’re ready to continue with caramelized white chocolate ganache.

CARAMEL WHITE CHOCOLATE GANACHE

• Over a bain-marie or microwave semi-melt the chocolate.
• In a small pot, over medium heat, add the heavy cream and glucose syrup and let it heat up just until it starts to bubble around the edges of the pot.
• Pour the heavy cream onto the melted chocolate in 3 parts and with a rubber spatula gently stir it together until homogenous.
• Place the cooled down chocolate mazarin cake back in the same (clean) 16 cm silicone mold lined with a cake collar and pour the ganache over the cake and even it out. Place in the freezer for a minimum of 3 hours.

MILK CHOCOLATE MOUSSE

• Bloom the gelatin sheets in cold water.
• Weigh out the greek yogurt and let it sit on the kitchen counter while preparing the milk chocolate and heavy cream.
• Meanwhile, heat up 75g of the 250g heavy cream in a small pot on medium heat until it boils. Take the pot off the heat and add the gelatine sheet. Stir it in until the gelatine has dissolved.
• Pour the heated heavy cream over the milk chocolate and with a spatula fold it together from the middle until cohesive.
• Add the milk chocolate mixture into the greek yogurt in 3 parts, to slowly combine the two mixtures.
• Whip the remaining heavy cream until soft peaks. With the rubber spatula, gently fold together the whipped cream in 3 parts with the milk chocolate mixture until smooth and combined. Take your 18cm silicone mold and place a small board under the silicone mold to make it easier to move the mousse into the freezer. Add a cake collar in the silicone mold as the cake will be taller than the mold. Pour the mousse into the mold.
• Take the cake out of the freezer and take off the cake collar. Place the cake upside down, with the caramel white chocolate ganache facing down into mousse, and place it in the center of the milk chocolate mousse.
• Gently lift the mousse cake into the freezer for a minimum of 6 hours or preferable overnight.

MIRROR GLAZE

• Bloom the gelatin sheets in cold water.
• Sift the cocoa powder over a bowl.
• In a small pot, stir together water, sugar, and condensed milk and heat to a boil. Then take it off the heat and add the gelatin sheets, squeezing the excess water off the gelatin, and stir it in.
• Hold the bowl at an angle and pour the hot liquid down the edge of the bowl to avoid creating air bubbles. With a rubber spatula gently stir the cocoa powder and liquid together until more cohesive. Then with a hand blend, blend the glaze together until smooth. Pour the mirror glaze in to a jug, holding the jug in an angle, to again avoid creating extra bubbles.
• Place a piece of cling film over the glaze, so it touches the surface of the glaze and allow the glaze to cool until it reaches a temperature between 33-34ºC.
• Prepare a baking tray with a piece of cling film. Place a cup upside down, for the cake to stand on.
• Once the glaze has reached the wanted temperature, take the mousse cake out of the freezer and out of the mold and place it on the cup.
• Pour the mirror glaze over the cake and let it drip off. Once set, remove any mirror glaze droplets hanging off the cake and lift the cake of the cup using two offset spatulas under the cake and gently lift over to your serving dish. Sprinkle with edible gold dust for decoration.
• Place it in the fridge to defrost for a 3-4 hours.
