Instructions

For the dough:. In a bowl, sift together the flour, baking soda, baking powder, 1 teaspoon pumpkin pie spice and cream of tartar. Set aside.
In a separate bowl, cream the butter and sugars until fluffy. Add the eggs, milk and vanilla. Mix well.

Cover bowl (or remove dough from bowl and wrap in plastic wrap) and chill for 2+ hours. You can chill for up to 24 hours if you have time.

When ready to bake, Preheat the oven to 350 degrees. Form the dough into 1 inch balls. Mix cinnamon, pumpkin pie spice and sugar in a small bowl and roll each ball of dough through the cinnamon and sugar mixture to coat well.
