Beat eggs, sugar and butter until frothy. Add flour, almonds, couverture, cinnamon and a pinch of salt and stir well. Spread the mixture on a baking sheet lined with baking paper.
Bake in the oven at 180 ° on the middle rack for about 25 minutes, until the surface is dry and no longer shiny.
Cut into 4 x 4 cm pieces while still warm, let them cool on the tray and cover with the chocolate icing. Decorate with the whole almonds.
