Preheat the waffle iron. Greasing is not necessary as the dough contains enough fat.
You need a heart waffle iron or Brussels waffle iron, not a special cinnamon waffle iron, as this is not about Christmas cookies.
Mix the butter, sugar, eggs and spices well, preferably with a hand mixer. Briefly stir in the flour and baking powder, add a little milk if necessary and stir. The dough shouldn`t be too firm or too runny, and it should come off the spoon easily.
Bake the dough in the waffle iron in portions according to the operating instructions.
The waffles taste good warm and cold.
Note:
Cinnamon has a very intense taste. If you want the waffles to taste balanced, i.e. vanilla with a fine note of cinnamon, please adhere to the quantities given.
