1/2 teaspoon salt
2 teaspoons baking powder
1 cup butter, room temperature (you can use unsalted, but I don't)
1 1/2 cup granulated white sugar
2 large eggs
1 teaspoon pure vanilla extract
3 Tablespoons white granulated sugar
1 Tablespoon fragrant Cinnamon (I use Vietnamese)
Preheat the oven to 350 degrees (F)
Sift the flour, baking powder, and salt into a bowl, set aside.
With a handheld or standing mixer, beat the butter until creamy.
Add the 1 1/2 cups sugar and continue beating until light and fluffy, about 5 minutes.
Add the eggs, 1 at a time, beating well after each addition.
Add the flour mixture and blend until smooth.
Mix the 3 tablespoons sugar with the cinnamon in a small bowl.
Roll the dough, by hand, into 1 1/2-inch balls. Roll the balls in the cinnamon sugar. Flatten the balls into 1/2-inch thick disks, spacing them evenly on ungreased cookie sheets.Bake until light brown, but still moist in the center, about 12 minutes. Remove
from pan and place on rack to cool.
