Dark Chocolate Coffin Mousse Ingredients

For the Mousse

Dark Chocolate (70% cocoa) – Opt for high-quality chocolate to achieve the richest flavor in your Dark Chocolate Coffin Mousse.
Heavy Cream – Whipping this will give your mousse its light and airy texture; coconut cream can be used for a dairy-free option.
Eggs (3 large, separated) – Fresh eggs are key for a fluffy mousse structure; separate the yolks and whites for the best results.
Granulated Sugar (1/4 cup) – This adds just the right touch of sweetness, balancing the rich chocolate—feel free to reduce or substitute if desired.
Vanilla Extract (1 tsp, optional) – While not mandatory, a splash of vanilla enhances the overall flavor complexity, making your mousse deliciously sophisticated.

Step‑by‑Step Instructions for Dark Chocolate Coffin Mousse

Step 1: Melt Chocolate
Begin by chopping 8 ounces of dark chocolate into small pieces and place it in a heatproof bowl. Set the bowl over a pot of simmering water (double boiler) or microwave it in 20-second intervals, stirring in between until fully melted and smooth. Allow the melted chocolate to cool slightly, ensuring it remains pourable for your Dark Chocolate Coffin Mousse.

Step 2: Whip Cream
In a separate large mixing bowl, pour in 1 cup of heavy cream. Using an electric mixer, whip the cream on medium speed until it forms soft peaks, which should take about 3-5 minutes. If desired, add 1 teaspoon of vanilla extract after a couple of minutes of whipping for added flavor. Once ready, set the whipped cream aside to maintain its airy texture.

Step 3: Prepare Egg Yolks
In another bowl, combine 3 large egg yolks with 1/4 cup of granulated sugar. Beat the mixture with an electric mixer until light and creamy, this should take about 2-3 minutes. Once pale and fluffy, gently fold in the cooled melted chocolate until fully incorporated, creating a rich base for your Dark Chocolate Coffin Mousse.

Step 4: Combine Mixtures
Next, take half of the whipped cream from Step 2 and carefully fold it into the chocolate and egg yolk mixture using a rubber spatula. Use gentle, sweeping motions to avoid deflating the mixture while combining until no white streaks are visible. This ensures your mousse will remain light and fluffy throughout.

Step 5: Whip Egg Whites
In another clean bowl, beat the 3 large egg whites until they reach stiff peaks, which indicates they are ready for folding. This process usually takes about 3-4 minutes using an electric mixer on high speed. Once achieved, carefully incorporate the beaten egg whites into the chocolate mixture in two additions, continuing to fold gently to maintain the airy consistency.

Step 6: Chill Mousse
Finally, transfer your Dark Chocolate Coffin Mousse mixture into coffin-shaped molds or individual cups. Smooth the tops with a spatula for an even finish. Cover with plastic wrap and refrigerate for a minimum of 2 hours, or overnight if time allows, to allow the mousse to set properly, developing its full flavor and elegant texture.
