The smell of warm cookies from the oven can put a smile on almost anyone's face.  Snickerdoodles are definitely one of the classics.  

Ingredients                                                                                                  Yield about 6 dozen cookies

1/2 cup vegetable shortening
1/2 cup butter, room temperature
   (using all butter will not work as well)
1 1/2 cup granulated sugar
2 eggs
2  3/4 cups of all purpose flour

2 tsp. cream of tartar
1 tsp. baking soda
1/4 tsp salt
3 Tablespoons granulated sugar
1 Tablespoon ground cinnamon

Directions

Preheat oven to 400 degrees.
In a large bowl, cream the shortening, butter, 1 1/2 cups sugar, and eggs until light and fluffy,
  Add flour, cream of tartar, baking soda, and salt:  stir until well blended.
In a small bowl, combine 3 Tbsp sugar and 1 Tablespoon of cinnamon
 Using your hands, roll dough into balls the size of small walnuts; rolll in the prepared sugar/cinnamon mixture.  Place cookies 2 inches apart onto ungreased cookie sheets.
Bake approximately 8-10 minutes or until light brown and just almost set.  ( these cookies firm up as they cool.)
Remove from oven and cool on wire cooling rack.  Cookie puff when they begin to bake and then flatten out with crinkled tops.
