The Best Chocolate Cake of the World

I saw this recipe in the newspaper the other day from a place that says that this is the best chocolate cake in the world. The big difference is that in this case the cake does not take flour or baking powder, which makes it lighter, almost like a mousse. Therefore it can be a great dessert, especially in cases in which the main dish is heavier. I thought of making this cake after a friend asked me if I had the recipe.
 
Ingredients
125g unsalted butter
250g bittersweet chocolate bar
6 egg yolks
6 egg whites
125g sugar
40g sugar
Ground almonds (optional)
 
Preheat the oven to 180oC. Grease a round of about 40cm in diameter. Melt butter and bittersweet chocolate together. Beat well the egg yolks with 125g sugar until creamy white to create a light and fluffy. Combine the two mixtures and add the almonds.

Beat well the egg white until thoroughly consistent and add more sugar 40g. Now is the most important part. Mix this eggs white with the rest, but it must be very slowly, without knocking, involving gently. The whites cannot "break" because the cake does not grow

Bake for about 30 minutes without getting too cooked. This is the hardest part because the oven cannot be opened and the cake cannot be fully cooked. The secret is the top, when you are ready and consistent.

If you want to sprinkle the cocoa powder or basking on top.
 
Bon Appetit !!!
