This Flourless Chocolate Decadence Cake is a rich and moist chocolatey cake, a chocolate heaven for all chocolate lovers out there. The cake consists of a mousse-like texture chocolate cake that simply melts in your mouth. It has a beautiful decoration in a flower pattern using a silky chocolate ganache.

The recipe for the flourless chocolate cake is very easy and quick to prepare. First, you simply melt chocolate with butter and let it cool slightly. Meanwhile, you mix the eggs with sugar until light in color and fluffy. Here you can choose your favorite extracts to add to your cake. I like rum, pistachio, or almond extract but feel free to bring your touch here. Then you incorporate the melted chocolate mixture and cocoa powder and this is it.

Besides chocolate, the cake is enriched with cocoa powder. It is essential to use good quality chocolate and cocoa powder to enjoy this cake at its best. This cake is baked in a water bath which ensures a smooth silky texture and even baking. If it is possible, try using a basic pan for this, that doesn’t have a removable base as it makes everything much easier. Otherwise, you have to wrap the pan in aluminum foil or heat-resistant plastic bags to make sure no water gets inside the pan.

You can definitely serve the cake by itself as it is rich and chocolatey enough to satisfy all chocolate lovers. But if you want to make this cake even more decadent, top the cake with a layer of chocolate ganache for a truly amazing experience for your taste buds. Even though ou can choose to simply spread the ganache on top of the cake but you can also pipe it in this beautiful flower pattern that makes it look so elegant and impressive. Add your favorite sprinkles over the top and here it is, a perfect cake for any occasion. 

Life is about indulgence, but you shouldn’t be too indulgent with this cake though. It is so rich, and consistent that I highly recommend serving it in thin slices. If you like chocolate you should definitely give this Flourless Chocolate Decadence Cake a try, it is a show-stopper. Enjoy!

    This cake is very decadent to say in the least. It is like a huge (perfect) brownie, but not as buttery. It is rich and moist, and terribly addictive (for those chocolate lovers)!
