Ingredients In Mirror Glaze Chocolate Mousse Bars
Chocolate Mousse Recipe:
- Gelatine: Gelatine is a setting agent that helps the mousse hold its shape. I softened it in cold water before I used it.
- Dark Chocolate: Dark chocolate with a high cocoa content provides the rich and intense chocolate flavor that forms the base of the mousse.
- Heavy Cream: Heavy cream, also known as whipping cream, adds creaminess and richness to the mousse.
- Chocolate Cookies: IO broke the cookies into pieces and added between the mousse layers. Over time, they soften and take on a cake-like texture, providing a delightful textural contrast.
Chocolate Mirror Glaze Recipe:
- Sugar: I used sugar to sweeten the glaze and give it a glossy finish.
- Water: Water is combined with sugar and other ingredients to create a syrup that forms the base of the glaze. More importantly, when properly prepared, results in the characteristic glossy appearance of the glaze.
- Cocoa Powder: Cocoa powder contributes to the chocolate flavor of the glaze and also adds depth to its color.
- Heavy Cream: Similar to the mousse, heavy cream is used in the glaze to add creaminess and richness.
- Gelatine: Gelatine is used to help the glaze set and create a smooth, mirror-like finish. It's bloomed in water before adding to the glaze.
Garnishes:
- Grated Chocolate: I chose grated chocolate to garnish the mousse bars, adding both visual appeal and a touch of extra chocolate flavor.
- Melted Chocolate: Melted chocolate is applied to acetate strips to create the decorative chocolate curls..
- Edible Gold Dust: I mixed edible gold dust with vodka to paint the chocolate curls for an elegant and luxurious finish. You could also use lemon extract.

How To Make Glazed Chocolate Mousse Bars
Chocolate Mousse Recipe:
Prepare Gelatine: Start by mixing gelatine with cold water in a small bowl. Allow the gelatine to sit for about 5 minutes. During this time, it will absorb the water and become soft and pliable.

Heat Cream: In a saucepan, gently heat the heavy cream. You want it to be just on the verge of boiling, so keep a close eye on it. As soon as it's about to boil, remove it from the heat source.
Melt Chocolate: Place your dark chocolate and bloomed in a heatproof bowl. Pour the hot cream over the chocolate and gelatine and let it sit for a couple of minutes. This will cause the chocolate to melt.
Use a stick blender to blend the mixture until it's completely smooth and the gelatine is fully dissolved in the chocolate mixture.

Strain the Mousse: To ensure an ultra-smooth texture, pass the chocolate mousse through a fine mesh strainer. This step removes any potential lumps and ensures a silky consistency.

Layering: Half-fill silicone mini loaf molds with the chocolate mousse mixture. Then, add a layer of broken chocolate cookies on top. These cookies will soften and take on a cake-like texture over time. Finally, pour the remaining mousse over the cookies.


Freeze Overnight: Place the molds in the freezer and allow the mousse bars to freeze overnight. This extended freezing time is essential for setting the mousse properly.

Chocolate Mirror Glaze:
Prepare Gelatine: Similar to the mousse, bloom gelatine in a small bowl with cold water. Let it sit for about 5 minutes.
Create Glaze Base: In a saucepan, combine water, sugar, cocoa powder, and heavy cream. Stir the mixture thoroughly and heat it over medium heat until it's nearly about to boil. Then, reduce the heat and let it simmer for 2 minutes, all while stirring continuously.


Dissolve Gelatine: Remove the saucepan from the heat source and add the bloomed gelatine. Stir vigorously to dissolve the gelatine entirely and ensure it's well-incorporated into the glaze.

Strain the Glaze: To eliminate any potential lumps or impurities, strain the chocolate glaze through a fine mesh strainer into a heatproof jug.
Cool to the Right Temperature: Allow the glaze to cool down to 35°C (95°F) to achieve the ideal consistency for pouring. If you don't have a candy thermometer, you can aim for lukewarm, which is still suitable.

Assembling the Bars:
Unmold Mousse Bars: Carefully remove the frozen mousse bars from the molds. They must be fully frozen when applying the glaze.

Glaze the Bars: Place each mousse bar on a wire rack with a tray underneath to catch any excess glaze. Then, evenly pour a thin layer of the chocolate mirror glaze over each bar. Allow any surplus glaze to drip off for a few minutes.


Transfer and Garnish: Gently move the glazed bars onto mini gold cake boards. For a finishing touch, garnish the lower rim of the mousse bars with finely grated chocolate.

Chocolate Decoration (Optional):
Create Chocolate Strips: Begin by applying melted chocolate to an acetate strip. Use an angled spatula to spread it evenly and run a cake comb along the strip for texture. Bend the strip into a circle and place it inside a cookie cutter for support. Let it dry thoroughly.


Gold Paint: Mix edible gold dust with vodka to form an edible gold paint. Use this mixture to paint the chocolate curls. Allow them to dry completely.


My Top Tip
The most important tip I can give you when making this chocolate mousse recipe is to make sure that the mousse bars are completely frozen before applying the mirror glaze. Freezing the mousse bars overnight makes them firm and solid. This means the glaze will coat the bars properly and you will be sure to get that amazing glossy finish. Attempting to glaze mousse bars that are not frozen enough can result in the glaze not setting correctly or slipping off. So, patience in the freezing step is really important for achieving the best results in both appearance and texture.

Variations And Substitutions
White Chocolate Mousse: Instead of dark chocolate, use white chocolate for a lighter and creamier mousse.
Milk Chocolate Mousse: Opt for milk chocolate if you prefer a less intense chocolate flavor in your mousse.
Fruit Fillings: Introduce fruit compote or fresh fruit slices between the mousse layers for a refreshing contrast. Berries, raspberries, strawberries, or passion fruit work well.
Nutty Crunch: Add a layer of crushed nuts, such as toasted almonds or hazelnuts, between the mousse layers for a satisfying crunch and nutty flavor.
Vegan Options: To make a vegan version, substitute heavy cream with coconut cream and use vegan-friendly dark chocolate. Agar agar can replace gelatine for setting. The process for activating agar agar is outline in detail in my Caramel Chocolate Panna Cotta recipe.
Gluten-Free: Choose gluten-free chocolate cookies or omit them altogether if you want to make the dessert gluten-free.
Low-Sugar: If you prefer a dessert with less sugar, use sugar substitutes or reduce the sugar content in both the mousse and glaze. Keep in mind that altering sugar content can affect the texture and consistency, so be cautious.
Decorations: Experiment with different decorations like fresh edible flowers, chopped nuts, or colorful sprinkles to add a unique touch to your mousse bars. You can also use a smidge of edible gold leaf!
Alcohol-Infused: Add a touch of your favorite liqueur, such as Grand Marnier or Amaretto, to the chocolate mousse for a boozy twist (be mindful of the amount to avoid overpowering the flavor).
