Ingredients:
1/2 cup butter, softened
1/2 cup white sugar
1/3 cup brown sugar
1 egg
1/2 teaspoon vanilla
1 1/2 cups flour
1/4 teaspoon salt
1 teaspoon baking powder
For rolling:
2 tablespoons granulated sugar
1 teaspoon cinnamon
Directions:
In a large bowl, cream together the butter and sugars.
Add the egg and vanilla and beat until smooth.
In another bowl, combine the flour, salt, baking soda, and cream of tartar.
Pour the dry ingredients into the wet ingredients and mix well.
Preheat oven to 300 degrees.
In a small bowl, combine the sugar with the cinnamon for the topping.
Take about 2 1/2 tablespoons of the dough and roll it into a ball.
Roll this dough in the cinnamon/sugar mixture and press it onto an un-greased cookie sheet.
Bake the cookies for 15 minutes.
The cookies may seem undercooked, but will continue to develop after they are removed from the oven. When the cookies have cooled they should be soft and chewy in the middle.
