To prepare the crepes you need 2 bowls: pour the milk and flour into one and mix together; combine the eggs and the butter in the other. Then mix together these 2 mixtures. Let the batter rest for 15 minutes at room temperature.
Grease a grill plate with absorbent paper containing oil. Heat up the grill plate and pour on some batter, creating crepes that are approximately 26 cm in diameter. Cook on both sides until they are consistently firm.
Spread some Nutella® onto each crepe and fold them over like a fan. Coarsely chop the hazelnuts, put the crepe on individual plates and garnish with the chopped hazelnuts. Serve immediately.
