This chocolate hazelnut mousse is creamy and decadent, while being light and fluffy. A mix of milk and dark chocolate, and infusing the cream with hazelnuts creates the perfect chocolate and hazelnut flavor. For a finishing touch, I've added a drizzle of roasted hazelnut oil that adds even more creamy hazelnut flavor. Smooth and stable, it's an effortless, no bake dessert that is perfect to make ahead and is sure to impress your next dinner party. Or make it and store in the freezer, for whenever you need a chocolate mousse fix! A big bowl of scoopable mousse is sure to make your life better (allegedly).
