In a small saucepan, whisk 2 eggs with the sugar until light and fluffy.
Place the saucepan over low heat and continue to stir with a whisk for about 3 minutes. Then add 100 gr of chopped dark chocolate and mix everything together.
Pour your chopped nuts into the saucepan, I used hazelnuts, and stir. Then add the crumbled macaroons and mix.
Cover a rectangular mold with baking paper, or alternatively a round 20 cm diameter hinged mold, and pour in the mixture. Level it out and place it in the freezer for about 30 minutes.
In the meantime, prepare the chocolate cream for the garnish: melt in a bain-marie, or in the microwave, 150 g of crumbled dark chocolate and then add the butter.
Once half an hour has passed, pour the melted chocolate over the base of your cakes, level it and put it in the freezer for 2 hours.
At this point make many small cubes and garnish with salt flakes. To make them even more beautiful you can also melt some white chocolate and with a teaspoon make some streaks.
Place in the freezer until you need to serve them. Before tasting them, however, leave them in the open air for 2 minutes, enjoy!
