A velvety, cloud-light mousse that tastes like melted hot cocoa upgraded into a chic, spoonable dessert.
If the mousse thickens too much, fold in 2–3 tablespoons of cold cream. Swap milk chocolate for semi-sweet if you prefer something sweeter. Great as a dip for fruit for toddlers, and excellent with flaky salt or crisp cookies for apéro-style dessert.
