Preheat the oven to 350℉. Line two baking sheets with parchment paper or a silicon baking mat.
In a large bowl using either a hand or stand mixer fitted with a paddle attachment, beat together the butter, brown sugar, and granulated sugar on medium high speed until fluffy and creamed, around 3 minutes. Add the egg and vanilla extract and beat on high speed until combined, around 1-2 minutes. Set aside.
In a medium bowl, whisk together the flour, cornstarch, baking soda, cloves, ginger, cinnamon, and salt. On low speed, pour these dry ingredients into the wet ingredients and beat until just combined. Keeping the mixer on low speed, add the chopped figs and walnuts and beat until combined, just 15 seconds or so.
Scoop the dough into balls about 2 tablespoons in size. Place on the baking sheet about 2 inches apart. Bake for 10-12 minutes or until beginning to brown on the sides. Remove the cookies from the oven. If they haven't spread much, carefully tap the tray on the counter a couple of times.
Let cookies cool for at least 10 minutes before eating. These are great warm or at room temperature. Cookies stay fresh for up to 5 days sealed in an airtight container.
