In a small bowl, stir together the sugar and cinnamon and set aside.

To make the cookie dough, stir together the dry ingredients.

In a bowl, cream the butter. Add the sugar and continue to mix, then add the eggs and vanilla and mix thoroughly.

Add the dry ingredients and mix until blended.

Chill dough 1 hour.

Preheat oven to 375 degrees F.

Roll balls of dough about the size of a walnut then roll them in the cinnamon sugar to coat. (may need more sugar and cinnamon to taste.)

Place on an un-greased sheet pan 2 1/2 inches apart.

Bake for 10-11 minutes until puffed up and the surface is slightly cracked.

Let cool on the sheet pan a few minutes before removing to a wire rack to cool.

These should be moist, not crisp so be careful not to over bake.
