This Chocolate Raspberry Mousse Cake is as beautiful as it is delicious and perfect for any occasion. If you want to really impress your sweetheart or your family with a dessert this cake will do the trick. It has a moist cocoa brownie at the bottom, topped with a crunchy chocolate raspberry crunch and a delightful raspberry mousse. The cake is then covered with a chocolate ganache and beautifully decorated with fresh raspberries. The smoothness of the mousse perfectly complements the crunchy layer, moist brownie, and rich ganache on top of this cake, which is nothing else but a great symphony of flavors and textures.
It is one of my top 5 favorite desserts of all time. It is amazingly delicious, however, it is a labor of love. It is going to take you a bit of time to make this cake, but I am 100% certain that once you try a slice of this mousse cake, you will think it was totally worth the effort. Hope you will try this out and enjoy as I sure did!

To make the cocoa brownie:
Preheat the oven to 325°F. Line a 8 inch springform pan with parchment paper, lightly grease.

Whisk together egg and sugar in a bowl until well combined. Whisk in oil and vanilla extract.
Add to the dry ingred̾i̾ents and beat well until the batter is smooth.
Pour the batter into the prepared pan.
Bake until the top no longer looks wet and a toothpick inserted in the center comes out with just a few moist crumbs.
Remove from the oven, let cool completely on the wire rack.
To make the chocolate raspberry crunch:

To make the chocolate glaze:
