This rich chocolate mousse has a secret ingredient making it dairy-free (hint: it's not coconut oil!). Dark and smooth, you won’t miss the milk (or milk substitute). Naturally flourless and perfect for Passover or an elegant dinner if you want a pareve (non-dairy) dessert, it’s a simple recipe with impressive, restaurant-worthy results.
Wipe out the bowl of a stand mixer with ¼ teaspoon white vinegar or lemon juice (to remove all traces of fat in the bowl).
Break 4 large eggs into a small bowl, remove the yolk into a medium bowl, and pour the whites into the stand mixer bowl. You can use an egg separator to help. No yolk can be in with the egg whites because the fat will keep the whites from whipping into a meringue. If an egg breaks, don’t use it, just get a new egg.
Place 6 ounces dark chocolate wafers, chopped solid chocolate, or chocolate chips in a medium microwave-safe bowl and melt in a microwave on high, stirring after each 30-second increment, until smooth. Let it cool slightly. Meanwhile, dissolve ½ teaspoon espresso powder in 1 tablespoon of boiling water and allow to cool slightly.
Stir ¼ cup extra virgin olive oil, rehydrated espresso, 2 teaspoons pure vanilla extract, and pinch kosher salt into the melted chocolate until combined. Set aside.
Place the egg yolks and ¼ cup granulated sugar in a medium bowl and whisk until the mixture is pale yellow. Add the yolk mixture to the chocolate mixture and stir until smooth.
Beat the egg whites in the bowl of a stand mixer fitted with a whisk attachment (or with a hand mixer) until soft peaks form. Gradually sprinkle in the remaining ¼ cup granulated sugar and beat just until stiff peaks form.
Add a generous spoonful of the egg white mixture to the chocolate mixture. Stir gently until completely incorporated. Transfer the chocolate mixture into the bowl of egg whites. Gently fold with a large spoon or rubber spatula until completely combined.
You can store it in a single bowl to portion out later or divide the mousse into 6-ounce ramekins and cover with plastic wrap. Wipe up any drips, cover with plastic wrap, and chill at least 4 hours or overnight.
To serve, garnish with a light sprinkling of cocoa nibs and/or sea salt flakes. Serve and enjoy!

Recipe Notes
This mousse contains raw eggs. If you're concerned about the risks of eating raw eggs, you can use pasteurized eggs without affecting the results.Use pure chocolate - the higher quality chocolate you purchase, the better your mousse will taste. The best type of chocolate to use are chocolate wafers or a bar of chocolate, but you can also use chocolate chips. Using dark chocolate (60 to 72% cacao) will result in a richer chocolate flavor, but you can use semisweet if you want to back off on the intensity.Same is true for the olive oil. Use the best olive oil you have, one whose flavor you enjoy. It's time to break out the good stuff here, people.Flavor variations: If you want to play with the flavor, here are a few ideas to add along with the vanilla:
Chocolate-Orange: 1 teaspoon of orange zest or ¼ teaspoon of Fiori di Sicilia (an orange-vanilla extract)
Chocolate Mocha: Increase the espresso powder to 1 tablespoon
Mexican Chocolate: 1 teaspoon of cinnamon and a pinch of cayenne (or to taste)
