How to cook
The eggs, sugar and butter, which have been slightly melted beforehand, are beaten well with a mixer until a smooth mixture is obtained.
Add the flour, cocoa and vanilla. All this needs to be beaten very well once again.
Pour the mixture into a baking pan, greased with oil or butter (optional). Carefully arrange the pre-cut walnuts on it, so it looks like a mosaic.
Press the walnuts lightly and bake the cocoa fudge in the oven at medium heat.
Once it's baked, cut the fudge into rhombus shapes.
Usually, when I say I'm going to make fudge, my family orders two doses!
