Flourless Chocolate Cake with Coffee Mousse

Watch the video for this recipe:

This Flourless Chocolate Cake with Coffee Mousse is one of my favorite decadent cakes that I’ve been wanting to share with you for quite some time. The flourless chocolate cake at the base is rich, chocolaty, dense and fudgy while the coffee mousse on top is full of aroma, soft and airy.  Chocolate and coffee have always made such a great pair and in this form it is absolutely heavenly. This is by far a rich cake for chocolate lovers, who will start to love chocolate even more from now on. 


The recipe is easy to prepare and you don’t need too many ingredients to make this unforgettable dessert. Even if this was not made on-purpose it is a gluten-free dessert, which makes it great even for those who have gluten intolerance. Try this recipe as soon as possible, it is a must for this year 🙂
