Place a flour sifter or fine mesh sieve over the top of a large mixing bowl. Add the flour, baking soda, spices, and salt to the sifter and sift the dry ingredients into the mixing bowl. Set aside.
2 ¼ cups (270 grams) all-purpose flour, 1 ½ teaspoons baking soda, 2 teaspoons ground ginger, 1 ½ teaspoons ground cinnamon, ¼ teaspoon ground cloves, ½ teaspoon salt
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter, brown sugar, and granulated sugar until smooth and creamy. Add the egg and vegetable oil and beat until well combined. Beat in the molasses and vanilla extract until mixed well, scraping down the sides of the bowl as necessary.
½ cup (1 stick) unsalted butter, ½ cup brown sugar, ½ cup granulated sugar, 1 large egg, 3 tablespoons vegetable oil, ¼ cup unsulphured molasses, 1 teaspoon vanilla extract
With the mixer on low speed, add ⅓ of the dry ingredients at a time, mixing until fully incorporated. Cover the cookie dough with plastic wrap and chill for one hour in the refrigerator.
About 20 minutes before the cookie dough is done chilling, preheat the oven to 375°F and line a baking sheet with parchment paper. Add about ½ cup of granulated sugar to a shallow bowl or plate. Roll a heaping ½ tablespoon of cookie dough into a ball shape, then roll each ball in the granulated sugar.
Additional sugar for rolling
Space the cookie dough balls evenly on the prepared baking sheet and do not flatten them. Bake the cookies for 8-9 minutes or until just set and beginning to crack on the top. Transfer to a cooling rack and cool completely before storing.
