Step 1

Preheat oven to 300 degrees F (150 degrees C).

Step 2

Combine the 3 tablespoons white sugar and the cinnamon in a small bowl and set aside.

Step 3

Blend dark brown sugar and white sugar in a large bowl with mixer on medium speed. Add butter and blend until grainy. Add eggs and vanilla extract, mixing until light and fluffy.

Step 4

Whisk flour, baking soda and salt together in a separate bowl. Add to sugar mixture, mixing at low speed just long enough to combine. Overmixing makes tough cookies!

Step 5

Roll dough into 1inch balls, then roll each ball into cinnamon-sugar to coat. Place cookies on ungreased cookie sheets and bake at 300 degrees F (150 degrees C) for 18 to 20 minutes. Remove from sheets and let cool on racks.
