Beat the egg yolks with the almond powder and icing sugar.
Once the mixture turns white, add the warm melted butter and set to one side.
Beat the egg whites with the granulated sugar until stiff.
Use a rubber spatula to mix the first mass with half of the egg whites and incorporate the flour into this mixture, as well as the cocoa powder, sieved in advance.
Finish off by adding the other half of the egg whites.
Take a sheet of baking paper and use a piping bag to form the mixture in a spiral shape, making the size smaller than the cake.
Bake for about 5 minutes in a preheated oven at 240°C.
