How to make
Put the hazelnut cream (Nutella is the one I use) for about 30 seconds to a minute in the microwave to liquefy.
If desired, you can mix the eggs with a mixer in advance.
Pour the chocolate into a bowl, add the eggs and sifted flour, then beat with a mixer, until a smooth mixture is obtained.
It is best to use a 10.2″ (26 cm) baking pan lined with baking paper on the bottom for this chocolate cake.
Bake chocolate cake with 3 products at 370°F (190°C) for 15-20 minutes.
