The chocolate biscuit base is very easy to prepare and is ready in a matter of minutes. I love using digestive biscuits for this recipe as they are not too sweet, a bit salty and have a nice crispy texture. Break the biscuits into smaller pieces and then combine with a thick and flavorful chocolate syrup. For the chocolate syrup I use cocoa powder, sugar and butter and some extract for extra flavor. This time I wanted to use rum extract but vanilla, almond, pistachio extracts for instance will be as good.  For this chocolate syrup I highly recommend using a good quality cocoa powder to ensure a good flavor.

The Mascarpone mocha mousse is very easy and quick to prepare as well. You simply need to mix the room temperature Mascarpone with some powdered sugar, instant coffee and vanilla extract. I usually like to add a bit of gelatin too, especially if served in very warm climate areas. Then you mix in some chilled whipping cream and the mousse is ready. Let the mousse set in the refrigerator for several hours before preparing the chocolate ganache.

I like to use semisweet chocolate for my chocolate ganache, but you can feel free to use milk chocolate, or even Nutella for the topping. 

If you love Chocolate Biscuit Cake you should definitely try this amazing dessert as well. Our friends and our family simply loved it and I am sure you will too. Enjoy!
