3 cups flour
1 tbsp cream of tartar
1 tsp baking soda
2 tsp cinnamon
1 tsp salt
1 cup butter, softened
1 1/2 cups sugar
2 eggs
2 tsp vanilla
1 large apple, peeled and shredded (about 1 cup) (I even did this with frozen apples as we had them leftover from summer)
1/4 cup sugar
2 tsp cinnamon
Preheat to 350. Line baking sheet with parchment paper and set aside.
In a medium bowl, combine flour, cream of tartar, baking soda, 2 tsp cinnamon and salt. Mix well and set aside. In another bowl, combine butter, 1 1/2 cup sugar, eggs and vanilla. Mix until creamy. Gradually add the flour mixture until combined. Fold in shredded apples.
In a small bowl, combine 1/4 cup sugar and 2 tsp cinnamon. Mix well. Form dough into 1 inch balls and then roll in cinnamon-sugar mixture and place onto prepared baking sheets.
Bake for 11-12 minutes or until done. Cool on wire racks.
Makes about 2 dozen cookies.
