Festive sprinkles or crushed candy canes for garnish
Instructions
Step 1: Prepare the Chocolate: Place the 10 ounces of chopped dark chocolate into a medium-sized heat-proof glass or metal bowl. Ensure the chocolate is chopped into small, even pieces so that it melts quickly and uniformly.
Step 2: Heat the Cream: In a small saucepan over medium heat, bring 1/2 cup of the heavy whipping cream to a gentle simmer. Do not let it reach a full rolling boil; you just want to see small bubbles forming around the edges.
Step 3: Melt and Smooth: Pour the hot cream directly over the chopped chocolate. Let it sit undisturbed for about 5 minutes to allow the heat to soften the chocolate. Afterward, stir the mixture gently with a whisk or spatula until it is completely smooth and glossy. Set this ganache aside to cool to room temperature.
Step 4: Whip the Remaining Cream: In a separate large chilled bowl, combine the remaining 1.5 cups of heavy whipping cream, sugar, vanilla extract, and a pinch of salt. Using a hand mixer or stand mixer, beat the mixture on medium-high speed until stiff peaks form. Be careful not to over-beat, or the cream will become grainy.
Step 5: Fold the Mixtures: Gently fold about one-third of the whipped cream into the cooled chocolate mixture to lighten it up. Once combined, add the remaining whipped cream and fold very gently using a rubber spatula. Continue folding until no white streaks remain, being careful not to deflate the air in the cream.
Step 6: Chill and Set: Spoon or pipe the mousse into individual serving glasses or ramekins. Place them in the refrigerator and chill for at least 2 hours, or until the mousse is firm and set. This allows the flavors to meld and the texture to become perfectly spoonable.
