Yield: 4 dozen cookies

1 1/2 cups granulated sugar
1/2 cup butter
1 teaspoon vanilla extract
2 eggs
2 1/4 cups all-purpose flour
1/2 cup unsweetened cocoa powder
1 teaspoon cream of tartar
1/2 teaspoon baking soda
1/4 teaspoon salt
2 tablespoon granulated sugar
2 tablespoons cinnamon

Preheat oven to 400 degrees F.

In a large bowl, combine the sugar and butter; beat until light and fluffy. Add vanilla extract and eggs and blend well. Add flour, cocoa, cream of tartar, baking soda and salt, and mix well.

In a small bowl combine 2 tablespoons sugar and cinnamon. Shape dough into 1-inch balls and roll in the sugar-cinnamon mixture. Place 2 inches apart on ungreased cookie sheets. Bake until set, about 8 to 10 minutes. Immediately remove from cookie sheets and let cool.
