1 ⅓cupsbread or all-purpose flour (weigh for best results)(170 grams)
Cinnamon Sugar: 2 tablespoons granulated sugar plus 2 teaspoons cinnamon
Instructions
Preheat oven to 375 degrees F. Line cookie sheets with parchment.
In a mixing bowl, combine the softened butter, sugar, vanilla and egg. Stir by hand or using medium speed of a mixer. The goal is to just stir until blended and not to whip.
Add the baking powder, cream of tartar and salt directly to the batter and beat until blended, then add the flour and stir until it is mixed in.
Using a small cookie scoop or a rounded teaspoon, scoop out balls of dough. They should be about 15 grams each. If the dough is very soft, you can chill the pre-formed balls for about 20 minutes.
Before baking, mix together the cinnamon and sugar. Roll dough balls in cinnamon sugar.
Place on cookie sheets and bake for for 8 to 10 minutes or until done.
