Snickerdoodles

This recipe was the one my mother made, and it is a New England original. Likely of German origin, or perhaps a German-English mashup, this is a sweet cookie, and so fluffy it could be a muffin top.

1 cup butter, softened
1 1/2 cups sugar
2 eggs
1 tsp vanilla
2 2/3 cups flour
1 tsp cream of tartar
1/2 tsp baking soda
1/4 tsp salt
2 Tbsp sugar
2 tsp cinnamon

Cream butter and sugar. Add eggs and vanilla.
Combine flour, cream of tartar, baking soda and salt. Beat flour mix into butter mix.
Shape into balls and chill for about an hour. Roll balls in a mixture of cinnamon and sugar.
Bake at 400 degrees for 8-10 minutes.
