Full Ingredients

For the Chocolate Peppermint Mousse

• 6 oz (170 g) dark chocolate, 60–70% cocoa, chopped small
• 2 tbsp (28 g) unsalted butter, cut into pieces
• 1 1/4 cups (300 ml) heavy whipping cream, divided
  • 1/2 cup (120 ml) for melting with the chocolate
  • 3/4 cup (180 ml) for whipping into the mousse
• 3 large eggs, separated, at room temperature (use pasteurized eggs if concerned about raw egg consumption)
• 1/3 cup (67 g) granulated sugar, divided
  • 2 tbsp (about 25 g) for the yolks
  • 3 tbsp (about 42 g) for the whites
• 1/2 tsp peppermint extract
• 1/2 tsp pure vanilla extract
• 1/4 tsp kosher or fine sea salt
• 1/3 cup (40 g) finely crushed peppermint candies or candy canes, plus more to taste

For the Whipped Cream Topping & Garnish

• 3/4 cup (180 ml) heavy whipping cream, very cold
• 2 tbsp (16 g) powdered sugar
• 1/2 tsp pure vanilla extract
• 2–3 tbsp extra crushed peppermint candies or candy canes, for sprinkling on top
• Fresh mint sprigs (optional, for a pretty green contrast)

Step-by-Step Instructions

Step 1: Chill your tools and prep the peppermint

Place a medium mixing bowl and the beaters or whisk attachment of your mixer in the refrigerator to chill; cold tools help cream whip faster and lighter. Separate your eggs, placing yolks in one small bowl and whites in another clean, dry bowl. Let them sit at room temperature while you prepare the other ingredients.

Place peppermint candies or candy canes in a zip-top bag and crush them with a rolling pin or the bottom of a heavy pan until you have fine bits with a few slightly larger pieces. You want texture, but no big sharp chunks. Measure out 1/3 cup (40 g) for folding into the mousse and extra for garnish later.

Step 2: Melt the chocolate base gently

Fill a small saucepan with about 1 inch (2.5 cm) of water and bring it to a gentle simmer. Place the chopped dark chocolate, butter, and 1/2 cup (120 ml) of the heavy cream into a heatproof bowl that fits snugly over the pan without touching the water (a makeshift double boiler). Set the bowl over the simmering water and stir frequently until the chocolate and butter are completely melted and the mixture is smooth and glossy.

Remove the bowl from the heat and let the chocolate mixture cool until it is warm but not hot, about 5–7 minutes. It should feel comfortably warm on your fingertip, not scalding; this helps prevent the eggs from scrambling when you add them.

Step 3: Make the flavored egg yolk mixture and combine

While the chocolate cools slightly, whisk the egg yolks with 2 tbsp (about 25 g) of the granulated sugar in a small bowl until the mixture is slightly thickened and lightened in color, 1–2 minutes by hand. Whisk in the peppermint extract, 1/2 tsp vanilla, and salt until smooth.

To avoid shocking the egg yolks, slowly drizzle about 1/4 of the warm chocolate mixture into the yolks while whisking constantly. Once incorporated, scrape this yolk mixture back into the bowl with the remaining chocolate and whisk until completely combined and velvety. Set aside at room temperature; the mixture will thicken a little as it stands.

Step 4: Whip the egg whites to soft glossy peaks

In a very clean, dry bowl, beat the egg whites with an electric mixer on medium speed until foamy. Gradually sprinkle in the remaining 3 tbsp (about 42 g) granulated sugar while continuing to beat. Increase the speed to medium-high and whip until the whites hold soft, glossy peaks that gently curl over when you lift the beaters, 2–3 minutes. Do not overbeat; stiff, dry whites are harder to fold and can deflate the mousse.

Gently loosen the chocolate mixture by folding in one large spoonful of the whipped egg whites with a spatula. Then fold in the remaining egg whites in 2–3 additions, using broad, gentle motions from the bottom of the bowl upward, rotating the bowl as you go. Stop folding as soon as you no longer see streaks of egg white. The mixture should look light, airy, and uniform.

Step 5: Whip the cream for the mousse

Retrieve your chilled mixing bowl and beaters from the refrigerator. Pour in 3/4 cup (180 ml) of the heavy cream. Using an electric mixer, beat on medium speed until the cream begins to thicken, then increase to medium-high and continue beating until soft peaks form. The cream should hold gentle peaks that stand up but still look smooth and slightly droopy. Take care not to overwhip to a stiff or grainy texture at this stage.

Add about one-third of the whipped cream to the chocolate-egg-white mixture and fold gently to lighten it. Then fold in the remaining whipped cream in 2 additions, again using broad, sweeping motions. Work slowly and stop as soon as the mixture is evenly blended; overmixing will knock out the air you just worked to create.

Step 6: Fold in the peppermint and portion the mousse

Sprinkle the finely crushed peppermint candies (1/3 cup / 40 g) evenly over the mousse mixture. Fold very gently just until the peppermint is dispersed throughout; a few faint streaks are fine. The mixture should look airy with tiny flecks of pink and white.

Spoon or pipe the mousse into 6 small dessert glasses, ramekins, or jars, filling each about 3/4 full. Lightly tap each glass on the counter to settle the mousse and smooth the surface if needed. Cover each serving loosely with plastic wrap, taking care not to touch the surface of the mousse, and refrigerate for at least 2 hours, or up to 24 hours, until fully chilled and set.

Step 7: Whip the topping, garnish, and serve

When you are almost ready to serve, make the whipped cream topping. In the same chilled bowl (rinsed and dried if needed), combine the remaining 3/4 cup (180 ml) heavy cream, powdered sugar, and 1/2 tsp vanilla extract. Beat on medium, then medium-high, until the cream holds medium to firm peaks that are fluffy but not grainy.

Remove the chilled mousses from the refrigerator. Dollop or pipe a generous swirl of whipped cream onto each one. Immediately before serving, sprinkle with extra crushed peppermint candies for a pretty red-and-white shower and, if you like, garnish with a small fresh mint sprig. Serve cold and enjoy the contrast of silky chocolate mousse, cool mint, and light whipped cream in every spoonful.

Pro Tips

• Use good chocolate. The flavor of the mousse depends heavily on the chocolate you choose. Pick a smooth, not overly bitter dark chocolate in the 60–70% range for a balanced, luxurious taste.
• Mind the temperature. If the chocolate is too hot when you add the egg yolks or whipped egg whites, the mixture can seize or deflate. Aim for “comfortably warm” to the touch, not hot.
• Fold, do not stir. When combining the chocolate with egg whites and whipped cream, use a gentle folding motion. Stiring vigorously will knock out the air and make the mousse dense instead of airy.
• Crush the peppermint just before using. Finely crushed candies melt slightly into the mousse, leaving little pockets of crunch. Crushing too far ahead can cause them to clump from humidity.
• Consider egg safety. This recipe uses lightly handled eggs. If serving to pregnant people, young children, or anyone immunocompromised, seek out pasteurized shell eggs or use a trusted egg-free mousse variation.

Variations

• Egg-free peppermint mousse: Skip the eggs. Melt the chocolate with 3/4 cup (180 ml) cream as directed, then cool. Whip 1 1/4 cups (300 ml) cream with 1/4 cup (50 g) sugar, vanilla, and peppermint extract to medium peaks. Fold the whipped cream directly into the cooled chocolate, then fold in crushed peppermint. Chill and top as directed.
• Mocha peppermint mousse: Add 1–2 tsp instant espresso powder to the chocolate while melting. The coffee flavor deepens the chocolate and pairs beautifully with the peppermint.
• White and dark swirl: Make a half-batch of the mousse with white chocolate (reduce sugar slightly) and a half-batch with dark chocolate. Layer or swirl them in each glass, then top with whipped cream and peppermint for a striking presentation.

Storage & Make-Ahead

The mousse itself can be made up to 24 hours in advance and stored, covered, in the refrigerator. For the best texture, keep the mousse in individual serving glasses rather than one large bowl, which can weep more over time. The peppermint candies folded into the mousse will soften as it sits, which many people enjoy, but for maximum crunch, do not fold them in more than 12 hours ahead. The whipped cream topping is best made the day you plan to serve; you can whip it a few hours in advance, cover the bowl, and refrigerate, then briefly whisk by hand to refresh before topping. Leftover assembled mousse will keep, covered, in the refrigerator for up to 2 days, though the peppermint garnish on top may dissolve and bleed a bit of color into the cream.
