Gather all ingredients.

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

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

Blend brown sugar and 1/2 cup white sugar in a large bowl with a mixer on medium speed. Add butter and blend until grainy. Add eggs and vanilla, mixing until light and fluffy.

Whisk flour, baking soda, and salt together in a separate bowl.

Add the dry mixture to the butter-sugar mixture, mixing at low speed just long enough to combine. Avoid overmixing.

Roll dough into 1-inch balls, then roll each ball in cinnamon sugar to coat. Place cookies on ungreased cookie sheets.
