This Gluten Free Marjolaine Mousse Cake is a delightfully nutty addition to your spread of sweets. Four layers of hazelnut dacquoise offer a slight crunch with a delicate, spongy interior. The layers are separated by three unique types of velvety mousse, ranging from chocolate on the bottom to praline in the center and vanilla on top. A rich chocolate topping adds a dose of decadence that ties this French-inspired treat together!
