In a medium bowl, whisk together the flour, ground ginger, ground cinnamon, ground cloves, ground nutmeg (if using), baking soda, and fine sea salt until well combined and no streaks of baking soda remain.
2 1/4 cups all-purpose flour, 2 teaspoons ground ginger, 1 1/2 teaspoons ground cinnamon, 1/4 teaspoon ground cloves, 1/4 teaspoon ground nutmeg, 1 teaspoon baking soda, 1/2 teaspoon fine sea salt
In a large mixing bowl, whisk the melted (but not hot) unsalted butter, neutral oil, dark brown sugar, and 1/4 cup granulated sugar until thick, glossy, and slightly lighter in color, about 1 minute by hand.
1/2 cup unsalted butter, 1/4 cup neutral oil, 3/4 cup dark brown sugar, 1/4 cup granulated sugar
Whisk in the molasses, egg, and vanilla extract until the mixture is smooth, dark, and shiny, with no streaks of egg remaining.
1/3 cup unsulphured molasses, 1 large egg, 1 teaspoon pure vanilla extract
Add the dry ingredients to the wet ingredients in two additions, stirring with a sturdy spatula or wooden spoon just until no dry flour remains. The dough should be soft, thick, and slightly sticky. If it seems very loose, let it rest for 5 minutes so the flour can hydrate.
2 1/4 cups all-purpose flour, 2 teaspoons ground ginger, 1 1/2 teaspoons ground cinnamon, 1/4 teaspoon ground cloves, 1/4 teaspoon ground nutmeg, 1 teaspoon baking soda, 1/2 teaspoon fine sea salt
Cover the bowl tightly and refrigerate the dough for at least 45 minutes and up to 24 hours. For thicker, bakery-style cookies, chill 2–4 hours.
When ready to bake, preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Scoop the chilled dough into 1 1/2-tablespoon portions (a medium cookie scoop works well). Roll each portion into a smooth ball, then roll in the remaining 1/4 cup granulated sugar to coat. Place the dough balls on the prepared baking sheets about 2 inches apart.
1/4 cup granulated sugar
Bake one sheet at a time on the middle rack for 9–11 minutes. The cookies should be set around the edges, puffed in the centers, and just starting to crack on top. The centers should still look slightly underbaked for a soft, chewy texture.
Remove the baking sheet from the oven and let the cookies cool on the pan for 5–7 minutes so they can finish setting and develop more crinkles. Then transfer carefully to a wire rack to cool completely.
Once completely cool, serve the cookies right away, package for gifting, or store in an airtight container at room temperature.
