Chocolate hazelnut pancakes

Place the flour, sugar, buttermilk and eggs in the stainless steel mixing bowl of the MixMaster. Mix with the whisk on low speed (1-4) until everything is mixed together. Continue at medium speed (5-7) and mix until the batter is smooth. Heat a large non-stick frying pan over medium heat. Grease the pan with some butter. Spoon ¹/³ cup of the mixture into the pan and tilt the pan to form a circle. Cook until the surface bulges. Turn the pancake and fry for another minute. Repeat with the remaining batter.
