unbleached all-purpose flour
Preheat the oven to 400℉ (200℃).
In a large mixing bowl, cream the cheese, 1 tablespoon of the butter and the sugar.
Do not beat. Stir in the eggs, one at a time, beating well after each addition.
Add the cinnamon, lemon rind, flour, and salt; blend well.
Butter the pan with the remaining 2 tablespoons of butter, using your fingers to spread the butter completely.
Pour the mixture into the prepared pan and bake for 12 minutes at 400℉ (200℃)., then reduce the temperature to 350℉ (180℃). and bake for another 25 to 30 minutes.
The knife should come out clean.
Cool the cake to room temperature, then sprinkle with confectioners' sugar.
