Beat the eggs with the mixer for at least 10 minutes. The volume should triple. Melt the Nutella in a water bath (you can also use the microwave). Allow to cool slightly.
As soon as the eggs are beaten, slowly add about 1/4 of the Nutella to the eggs and mix carefully with the whisk. Gradually fold in the rest of the Nutella.
Preheat the oven to 170 ° C fan-assisted air. Line a round baking pan with parchment paper and grease a little. Better to choose a small baking pan, because the cake will collapse. I took one with a diameter of 22 cm.
Pour the dough into the mold and bake for about 25 minutes. The cake rises high, but collapses later. Let the finished cake cool down a bit and take it out of the mold. Sprinkle with powdered sugar.
Vanilla ice cream, whipped cream, strawberries - or everything together tastes good with it.
I got this very special cake from my friend in Italy. You only need two ingredients! I and my family liked the cake very much. The cake tastes like brownies and soufflé at the same time and is very chocolatey.
