These have the most addicting texture. Makes about 24 though I am a horrible cookie measurer.
2 sticks unsalted butter, softened
1 1/2 cups sugar
2 large eggs
1 tsp vanilla
2 3/4 cup flour
1 1/2 tsp cream of tartar
1/2 tsp baking soda
1 tsp salt
for cinnamon sugar: 1/4 cup sugar, 1 1/2 tbs cinnamon
Preheat oven to 350º. In a large mixing bowl, cream together butter and sugar for about 5 minutes or until fluffy. Scrape down the sides of the bowl and add eggs and vanilla; mix well. Add baking soda, salt, and cream of tartar, and mix until combined. Mix in the flour in parts.
If you have time, chill the dough for 30 minutes - optional.
Combine the cinnamon sugar in a small bowl. Form 1 inch balls of dough, and roll them in cinnamon sugar. Place on the cookie sheet and gently press down.
Bake for 9-10 minutes or until barely golden on the bottoms. Remove from cookie sheet immediately.
