Decadent Chocolate and Salted Caramel Mousse Cake Recipe

Jump to Recipe

A chocolate and caramel mousse cake that’s pure indulgence. This triple-layer dessert combines a chocolate almond cake base, a caramelized white chocolate ganache, a light milk chocolate mousse, and a glossy cacao mirror glaze for a show-stopping finish.

The standout here is the caramelized white chocolate ganache, which adds a deep, buttery caramel note without overpowering the chocolate layers. The marzipan in the almond cake complements the textures and flavors, keeping the dessert balanced rather than heavy. It’s a recipe you’ll want to make again and again.

STEP-BY-STEP INSTRUCTIONS – CHOCOLATE ALMOND CAKE

For the full ingredient list, see the recipe further below.

Preheat the oven to 180ºC (conventional).

Prepare a 16 cm silicone mold or cake tin and line the bottom with parchment paper.

Sift together the flour, baking powder, salt, and cocoa powder. Set aside.

Coarsely grate the marzipan and combine it with the butter and granulated sugar in a mixing bowl. Beat on medium speed for 1–2 minutes until light and fluffy.

Add the eggs one at a time, mixing on low speed until incorporated.

Add the dry ingredients and mix on low speed until just combined.

Finally, add the milk and mix until the batter is smooth and blended.

Pour the batter into the prepared mold and bake for 22–25 minutes. If using a metal tin, the cake may bake a few minutes faster—check early.

Cool the cake on a rack. When it is cool enough to touch, remove it from the mold and let it cool completely. Once cooled, return it to the clean mold and wrap a cake collar around it to make the next steps easier.

STEP-BY-STEP INSTRUCTIONS – CARAMELIZED WHITE CHOCOLATE GANACHE

Gently melt the caramelized white chocolate over a bain-marie or in short bursts in the microwave.

Heat the heavy cream with the glucose syrup in a small pot over medium heat until it begins to bubble at the edges.

Pour the warm cream over the melted chocolate in three additions, stirring gently with a rubber spatula until smooth and homogeneous.

Place the cooled chocolate-almond cake back into the cleaned 16 cm silicone mold with the cake collar, pour the ganache over the cake, and smooth the surface. Freeze for at least 3 hours.

STEP-BY-STEP INSTRUCTIONS – MILK CHOCOLATE MOUSSE

Soak the gelatin sheets in cold water to bloom.

Measure the Greek yogurt and leave it at room temperature while you prepare the chocolate and cream.

Warm 75 g of the 250 g heavy cream in a small pot over medium heat until it just comes to a boil. Remove from heat and stir in the dissolved gelatin until it melts completely.

Pour the hot cream over the milk chocolate and fold gently from the center until the mixture is smooth and cohesive.

In three additions, fold the chocolate mixture into the Greek yogurt to combine slowly and evenly.

Whip the remaining heavy cream to soft peaks. Fold it into the chocolate-yogurt mixture in three parts until smooth.

Prepare an 18 cm silicone mold: place a small board under it to help move the mousse to the freezer, and line it with a cake collar since the assembled cake will be taller than the mold. Pour the mousse into the mold.

Remove the chilled cake with ganache from the freezer and remove its collar. Invert the cake so the ganache layer faces downward and position it in the center of the milk chocolate mousse.

Freeze the assembled mousse cake for at least 6 hours, preferably overnight.

STEP-BY-STEP INSTRUCTIONS – MIRROR GLAZE

Bloom the gelatin sheets in cold water.

Sift the cocoa powder into a bowl and set aside.

In a small pot, combine the water, granulated sugar, and condensed milk. Heat to a boil, then remove from heat and stir in the squeezed gelatin until dissolved.

Pour the hot liquid down the side of the bowl to minimize air bubbles. Stir in the sifted cocoa powder until cohesive, then blend briefly with a hand blender until smooth. Transfer the glaze to a jug, holding it at an angle to avoid introducing extra bubbles.

Cover the surface of the glaze with cling film so it touches the liquid, and allow it to cool to 33–34ºC.

Line a baking tray with cling film and place an inverted cup in the center to support the cake while glazing.

When the glaze reaches the target temperature, remove the mousse cake from the freezer and the mold. Set the cake on the inverted cup and pour the glaze evenly over the top, letting it drip off the sides.

After the glaze sets, trim any hanging droplets and transfer the cake to a serving plate using two offset spatulas. For a touch of elegance, dust with edible gold dust. Refrigerate to thaw for 3–4 hours before serving.

STORAGE

Store the cake in the refrigerator, covered or in an airtight container. It’s best enjoyed within a few days for optimal texture and flavor.
