This is a favorite because I freeze the dough, and just grab 3 or 4 now and then when we crave them. These go on the cookie tray every Christmas 
I put the dough in freezer bags with oven temp , time, and name
Easy cookie and pretty, besides cinnamon delicious

Snickerdoodles

Ingredients
1/2 cup butter, softened
1/2 cup shortening
1 1/2 cups white sugar
2 eggs
2 teaspoons vanilla extract
2 3/4 cups all-purpose flour

2 teaspoons cream of tartar
1 teaspoon baking soda
1/4 teaspoon salt
3 tablespoons white sugar
2 1/2 teaspoons ground cinnamon
Directions
Preheat oven to 400 degrees F (200 degrees C).
Cream together butter, shortening, 1 1/2 cups sugar, the eggs and the vanilla. Blend in the flour, cream of tartar, soda and salt. Shape dough by rounded spoonfuls into balls.
Mix the 3 tablespoons sugar and the cinnamon. Roll balls of dough in mixture. Place 2 inches apart on ungreased baking sheets.
Bake 8 minutes. Let sit on baking sheet if you take these out at 8 minute mark - sit for a few minutes before moving to wire rack. The dough balls will freeze well - roll ball in sugar - place on a dish - put in freezer for 15 minutes and then drop balls in to a ziploc bag marked with name; oven temp and 8 minutes I saw this recipe on an Allrecipes website
