I have a daughter who loves Snickerdoodles:
2 2/3 cups flour
1 cup shortening
1 1/2 cups sugar
1 teaspoon baking soda
1/2 teaspoon salt
1/4 teaspoon cream of tartar
2 teaspoons sugar mixed with 2 teaspoons cinnamon for rolling cookies in
Cream together the shortening and sugar. Add eggs, one at a time and beat well. Sift together the flour, baking soda and salt. Stir the sifted ingredients into the other ingredients and mix. Chill for one hour.
Make small balls and roll them in the sugar and cinnamon. Place on ungreased cookie sheet. Bake at 400 degrees 8-10 minutes.
