Adapted from All Recipes
1 cup butter, at room temperature
1 1/2 cups sugar
2 teaspoons vanilla
2 3/4 cups flour
2 teaspoons cream of tartar
1 teaspoon baking soda
Dash of salt
2 tablespoons sugar
2 teaspoons cinnamon
Preheat oven to 400º.
With mixer, cream together butter and 1 1/2 cups sugar. Mix in eggs and vanilla. Add the flour, cream of tartar, baking soda and salt. Mix till combined.
Scoop out rounded teaspoonfuls of dough and shape into balls.
Mix the 2 tablespoons of sugar with 2 teaspoons of cinnamon in a small bowl. Roll dough balls in mixture. Place about 2 inches apart on baking sheet. I use a sheet of parchment paper on my baking sheets for easy clean up.
Bake 8 to 10 minutes or till set. Remove immediately to cooling rack.
*You may freeze the dough balls by placing them on a baking sheet (mine were already rolled in the cinnamon sugar), then freezing till hard. Remove to a ziplock bag and store in freezer till you want fresh cookies. Defrost overnight in refrigerator, and bake as directed. Since the defrosted dough is cold, the cookies may take an extra couple minutes in the oven.
