Preheat oven to 350 degrees and grease or spray a baking sheet with Baker's Joy.
In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt. Set aside.
In a mixing bowl, combine the softened butter and brown sugar.
Then add the egg, brewed coffee, and vanilla to the butter-sugar mixture and combine well.
Slowly add the flour mixture to the wet ingredients and combine to form a dough. Do not overmix.
Put about ½ cup of white sugar on a plate.
Form the dough into 1-inch balls, roll them in the white sugar, and place them on the greased baking sheet about 2 inches apart.
Bake at 350 degrees for 9-10 minutes.
