Snickerdoodles

1/2 cup butter- room temp
1/2 cup butter flavored shortening
1 1/2 cup sugar
2 eggs
2 tsp. vanilla
2 3/4 cup flour
2 tsp. cream of tartar
1 tsp. baking soda
1/4 tsp. salt

Cream butter, shortening, sugar, eggs and vanilla until well blended. Add flour, tartar, soda and salt. Mix well. Roll into balls about the size of a walnut and then roll in mixture of cinnamon and sugar. I have a bowl of this made up and really let the dough get coated really well. Bake at 400 for 8-10 minutes.
