1 3/4cupheavy cream or heavy whipping creamdivided; do not sub with milk or half and half
6tablespoonsgranulated sugardivided

Instructions
Separate the eggs when they're cold. Place the whites in the bowl of a stand mixer and allow to come to room temperature, and place the yolks in a large bowl.
3 large eggs
Place the chopped chocolate in a medium bowl. Heat 3/4 cup of cream in a small saucepan over medium heat just until bubbles form around the edges and it begins to steam. Remove from heat and pour it over the chopped chocolate and allow it to stand for 1-2 minutes to soften. Once the chocolate has softened, stir or whisk the mixture slowly until smooth, about 1-2 minutes. If there are any stubborn bits of chocolate that won't melt, heat at 50% power in the microwave for about 20 seconds and stir slowly. Be careful not overheat it and scorch the chocolate.
6 ounces good quality bittersweet chocolate bars or wafers, 1 3/4 cup heavy cream or heavy whipping cream
While the chocolate is softening, add 1/4 cup sugar and vanilla to the egg yolks. Whisk until thick and pale yellow, about 1 minute.
Slowly whisk the warm chocolate ganache into the egg yolk mixture, whisking constantly until combined. Set aside.
Beat the egg whites at medium high speed. Once the mixture is foamy and glossy, slowly sprinkle in the remaining 2 tablespoons of granulated sugar with the mixer running. Continue to beat until stiff, glossy peaks form. Dip the wire whip in the egg whites and turn upside down....the egg whites should stand up.
Whisk the chocolate mixture once more to make sure that it's still soft (if it cools too much it can become solid). If it's solid, heat at 50% power in the microwave for 10-15 seconds and stir slowly until smooth -- do not overheat as the chocolate can separate or seize. From there, make sure the temperature of the chocolate is just barely warm to the touch, then gently fold in 1/3 of the egg white mixture until almost incorporated. Add the remaining egg whites and fold in gently. It's ok if a few white streaks remain.
Wipe out the bowl used to whip the egg whites and add the cream. Beat until stiff peaks form, then fold gently into the chocolate mixture until combined.
Pour the mousse into a large serving dish or divide the chocolate mousse into 6-8 individual dishes depending on size. Chill for a minimum of 4 hours or up to 1 day in advance. Serve with additional whipped cream and shaved chocolate, if desired. Enjoy!
Notes
Pro tip: The first step is to separate your eggs as they're easier to separate when they're cold, and egg whites whip much faster when they're room temperature.
Chocolate. Be sure to use good quality chocolate baking bars or wafers. For this recipe, use chocolate with a cocoa content of at least 50% (this includes semi-sweet and bittersweet chocolate). Keep in mind that the darker the chocolate, the less sweet your chocolate mousse will be, so adjust the amount of sugar as needed. Milk chocolate and white chocolate cannot be substituted here as the amount of cream would need to be adjusted.
This dark chocolate mousse is made the classic French way, which includes raw eggs. Use eggs that have been pasteurized to reduce any risk of salmonella. To be on the safe side, cook the eggs and sugar gently over a double boiler, whisking often, until the mixture reaches 160 degrees. From there, add the vanilla and stir, then combine it slowly with the ganache.
Store mousse in the refrigerator for up to 3 days.
