Cinnamon Cakes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

Break the eggs into a bowl and whisk with rose water.
Add sifted sugar and pounded cinnamon, mixing well.
Gradually add flour until a good paste forms.

Shape and bake

Roll out the dough and cut into desired shapes.
Bake on parchment paper at 350°F (175°C) until done.
Remove from paper and store in a dry place.
