Use quality chocolate and let the cake chill accordingly.

When making this cake it is important to use quality chocolate. I get mine at trader joes supermarket. They have pound plus Belgium chocolate which has good quality for an affordable price. Other chocolate that I can recommend is Ghirardelli or Merckens.

Key to success for this cake is to let the cake chill long enough so that each mousse layer has enough time to set. The waiting time is the biggest part of making this cake, which is also good since you have enough time to clean the bowls and to prepare the next chocolate mousse layer in between.

Using gelatin powder instead of sheets? Substitute 1 sheet gelatin with 1 teaspoon powdered gelatin

A few trouble shooting tips ahead: When working with gelatin it is important to never let the gelatin cook since it would loose its gelation properties. Additionally, try to work fast after adding the gelatin chocolate mixture to the whipped cream since it tends to set quickly which would make it difficult to fill into the cake ring. Which actually happened to me while recording this recipe. When you watch my video check the consistency of the dark chocolate mousse. It was pretty set already when I layered it on top of the almond cake. It was more difficult to smooth it out without leaving air gaps underneath but it was still ok.

With all these tips you are set to make this beautiful cake without any complications. If you have any questions feel free to write me or leave a comment!
