Preheat the oven to 375 degrees with the racks on the upper and lower mid-position.

Whisk together the flour, baking solda, salt, and spices and set aside.

In a stand mixer, cream the butter, brown sugar, 1/2 cup of the granulated sugar for about 3 minutes, or until light and creamy.

Add the egg, vanilla extract, and molasses, making sure to scrape down the sides of the bowl.

Add the dry ingredients and mix at low speed for about 30 seconds, until just combined.

Place the remaining granulated sugar in a shallow dish.

Using a spoon or cookie scoop, divide the dough into approximately 2 tablespoon portions and roll into balls.

Roll the balls in sugar and place them on your cookie sheet, giving them 1 1/2 to 2 inches of space.

Bake 11 to 13 minutes, rotating the sheets in the oven about halfway through, until the outer edges just begin to set.

Allow to cool on the cookie sheets for 2 to 3 minutes before transferring to a wire rack.

When the cookies are cooled, drizzle with glaze (see recipe for glaze) and allow to set.
