Torta tenerina comes from Ferrara, in Emilia-Romagna — the name means "little tender cake," which is an accurate description of what happens when you take it out of the oven. The crust cracks and sets; the interior stays soft, almost molten, denser than a mousse but lighter than a brownie. Five ingredients: dark chocolate, butter, eggs, sugar, and just enough flour to hold it together — the ratio is what makes it different from every other chocolate cake.
The technique is simple but the timing matters. The tenerina cake is done when the edges are set and the center still has a slight tremble — pull it too early and it collapses, too late and you lose the fudgy interior that defines it. It keeps well for several days at room temperature, which actually improves it: the chocolate flavor deepens and the texture becomes even more cohesive. Serve it dusted with powdered sugar, or alongside whipped cream or vanilla ice cream if you want to balance the intensity. Fresh berries do the same job with less richness.

To prepare the cake, finely chop the chocolate 1, then transfer it to a bowl in a pan with water (the water should not come into contact with the bottom of the bowl or pot in which you poured your chocolate) and melt in a bain-marie, stirring continuously 2. When the chocolate has melted, but is not too hot, add the chopped butter 3
and let it melt while continuing to stir 4. Since the exact melting temperature of chocolate is around 120° F (50° C), the butter should only be added when the chocolate has melted, making sure that it does not exceed its melting point (which is about 90° F, or 32° C), and thus preventing it from separating. Let the chocolate and butter mixture cool, stirring occasionally. In the meantime separate the yolks from the egg whites in two separate large bowls. Add the sugar to the egg whites 5 and beat them until a firm, frothy mixture is obtained 6.
Set the beaten egg whites aside and pour the remaining sugar into the yolks 7, then beat them at a moderate speed until you obtain a clear, frothy mixture 8. While continuing to blend, pour in the now lukewarm chocolate and butter mixture 9,
and keep mixing until a uniform texture is obtained 10. Add the whipped egg whites in several stages: initially add about 1/3 of the egg whites 11 stirring with a spatula 12 or whisk.
Then incorporate the remaining egg whites by gently stirring from the bottom up 13. Sprinkle in the flour 14 and stir with a spatula, using gentle movements from bottom to top 15
until smooth and uniform 16. Grease with butter and sprinkle some flour a 9-inch (23 cm) springform cake pan (this will make it easier to remove the soft cake), and pour in the freshly prepared dough (17-18). Bake in a static oven preheated to 355° F (180° C) for 30-35 minutes (we do not recommend the use of a ventilated oven, as it could cook the cake unevenly).
Once out of the oven 19 let your moist chocolate cake cool before removing it from the pan 20 and sprinkling with powdered sugar 21.
