BEST 2-Ingredient Mousse

To achieve a high-quality mousse with only two ingredients, we rely on Fat-Protein Emulsification. In this 2026 refined method, we skip the eggs and gelatin, using the natural stabilizers found in heavy cream to “trap” the chocolate molecules in a suspended state.

The Science of the “Flash-Set”

The Crystal Lattice: Chocolate contains cocoa butter, which is a polymorphic fat. When melted and then folded into cold whipped cream, it begins to form a solid lattice.
Aeration: By whipping the cream to “soft peaks” before adding the chocolate, you create millions of tiny air bubbles. The chocolate then coats these bubbles, creating a structure that is both light and stable.

Ingredients List

High-Quality Dark Chocolate (4 oz / 115g): Minimum 60% cocoa for the best structural set.
Heavy Whipping Cream (1 cup / 240ml): Must be cold (4°C or lower).

Timing: The “Set-Point”

Prep: 10 minutes.
Chilling: 30 minutes (Minimum).

Step-by-Step Instructions

Step 1: The Gentle Melt

Finely chop the chocolate. Melt it using a double boiler or in 20-second bursts in the microwave.

The Pro-Hack: Let the chocolate cool until it is no longer hot to the touch but still liquid (approx. 32°C). If it’s too hot, it will deflate the cream; if it’s too cold, it will create “strands” or “chips” rather than a smooth mousse.

Step 2: The Soft Peak Whip

In a cold bowl, whip 43 cup of the heavy cream until soft peaks form.

Step 3: The Ganache Base

Take the remaining 41 cup of liquid cream and stir it into your melted chocolate. This creates a “ganache” that is closer in temperature and texture to the whipped cream, preventing the chocolate from seizing.

Step 4: The Fold

Gently fold the chocolate-ganache into the whipped cream using a silicone spatula.

Movement: Use a “cut and fold” motion—cut through the center, scrape the bottom, and fold over. Stop the moment the color is uniform to keep as much air as possible.

Step 5: The Set

Spoon into ramekins or glasses. Chill for at least 30 minutes.

Common Mistakes to Avoid

Over-whipping the Cream: If you whip the cream to “stiff peaks” before adding the chocolate, the final mousse will have a grainy, “buttery” texture.
Using Milk Chocolate: Milk chocolate has a lower cocoa butter content and higher sugar content; it often results in a “soupier” mousse that doesn’t set as firmly as dark chocolate.
Temperature Shock: Never add hot chocolate directly to cold cream. It will cause the fat in the cream to melt and the chocolate to seize into hard bits.
