Preheat oven to 375°F and line baking sheets with parchment or silicone mats.
In a bowl, whisk the flour, cloves, ginger, baking soda, cinnamon, and salt until evenly combined. Set aside.
In a mixing bowl, beat the vegetable oil and sugar until well blended.
Mix in the molasses, then add the egg and beat until incorporated.
Switch mixer to low and gradually add the whisked dry ingredients. Mix until just combined.
Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or until firm.
Baking
Using a tablespoon scoop or spoon, form 1-inch balls and roll each in granulated sugar.
Place the dough balls about 2 inches apart on prepared sheets.
Bake for 8-10 minutes. Cookies will look puffy when done.
Let cookies rest on the baking sheet for about 5 minutes, then transfer to a cooling rack.
Notes
For a slightly richer flavor, swap half the oil for melted butter. Gluten-free option: use a 1:1 measure gluten-free blend with xanthan gum. Store in an airtight container at room temperature for up to a week. Freeze for up to 3 months.
