1Heat oven to 375°F (if using dark or nonstick pan, heat oven to 350°F). In large bowl, beat 1 1/2 cups sugar, the butter, vanilla and eggs with electric mixer on medium speed, or mix with spoon, until creamy. Stir in flour, cream of tartar, baking soda and salt. Stir in cinnamon chips and pecans.
2In small bowl, mix 2 tablespoons sugar and the cinnamon. Shape dough by 1/4 cupfuls into balls. Roll in sugar-cinnamon mixture. Place balls 3 inches apart on ungreased large cookie sheet (do not flatten).
3Bake 13 to 17 minutes or until set and light brown. Immediately remove from cookie sheet to wire rack.
