The eggs are separated and the egg whites are beaten until stiff and then set aside. Tip: The egg white stiffens faster when the bowl is cold.
Now whip the egg yolks with the butter, sugar, vanilla sugar and salt until frothy.
The baking powder is mixed into the flour and is then alternately added to the egg yolk mixture with the milk and stirred. Then the bananas are mashed and put into the dough with the cinnamon. Finally, the egg white is slowly folded in.
Then you can bake the batter in your waffle iron in portions to make waffles.
