Snickerdoodles

2 3/4 C flour
1 tsp baking soda
1/2 tsp salt
1/2 C shortening
1 stick unsalted butter, softened
1 1/2 C sugar + 3 tbsp
2 eggs
1 tbsp ground cinnamon

Mix flour, soda and salt. Beat together shortening and butter, and add sugar, then eggs, then dry ingredients. Mix cinnamon and the rest of the sugar. Roll the dough (I prefer chilling the dough for a few minutes before) into 1 inch balls and roll around in the cinnamon sugar mixture. Place on baking sheet and flatten with a cup. Bake about 12 minutes at 350 degrees.
