This 2-ingredient chocolate mousse recipe is the easiest mousse dessert ever! All you have to do is pour the hot milk over the chocolate and whisk the mixture! Made with no eggs, it can be vegan if you use dairy-free milk and dark chocolate.
Finely chop the chocolate with a sharp knife (this will ensure that it will melt quickly and homogenize perfectly). Then, transfer it to a medium bowl.
Heat the milk until almost boiling, pour it over the chopped chocolate and let it rest for 1 minute.
Gently stir with a whisk until the chocolate is completely melted and the mixture is smooth. Taste it and if needed, add the sweetener.
Make the ice bath: Fill a larger bowl with ice and cold water (you can skip the ice-bath and chill the mixture in the fridge until it reaches 68ºF - 20ºC).
Whip the mixture with a whisk or an electric hand mixer until very soft peaks form (it should have the consistency of a thin chocolate cake batter). Don't over-mix or the texture will be grainy (if you notice stiff peaks form, you have gone too far).
Using a rubber spatula, divide the chocolate mixture between each glass (or cup) and chill in the fridge for at least 20 minutes.

Notes
For 2 servings it takes approximately 4 minutes to thicken, when using a whisk.
As you whip the chocolate mixture, it will start to lose its shine and become thicker. From that point on, it will thicken very quickly. Pay attention and stop when it reaches the consistency of thin chocolate batter, and while it's still pourable. Resist the urge to whip the mousse until firm because it will have a grainy texture. The mixture will continue to thicken in the fridge.
If you overmix the chocolate mixture and becomes very thick you can either eat it as is (it's still edible) or reheat it until melted and start over.
Add a teaspoon of whiskey (or brandy) per serving. It will be 50% better!
