Line a baking sheet with parchment paper and set aside.
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and both sugars.
½ cup unsalted butter, ½ cup granulated sugar, ½ cup light brown sugar
Add the egg and mix until fully incorporated, scrape down the bowl half way through mixing and add vanilla.
1 large egg, 2 teaspoons vanilla extract
In a separate bowl whisk together the flour, corn starch, baking soda, salt, cinnamon, ginger, and nutmeg until they are all mixed together.
2 cups all purpose flour, 1 tablespoon corn starch, 1 teaspoon baking soda, ½ teaspoon fine sea salt, 1 teaspoon ground cinnamon, ¼ teaspoon ground ginger, ½ teaspoon ground nutmeg
Add the dry ingredients into the stand mixer and mix on medium-low speed until dry ingredients are just mixed together.
While the mixer is on the lowest speed, slowly add the carrots and pecans. Mix just until combined, do not over mix dough.
1 cup finely shredded fresh carrots, ½ cup chopped pecans
Using a 3 tablespoon cookie scoop, scoop out the dough into balls and place on the parchment lined cookie sheet. Cover with plastic wrap and place the dough balls into the freezer to set for at least an hour.
Preheat the oven to 350°F and line a separate baking sheet with parchment paper. Place the dough balls on the cookie sheet about 1 1/2 inches apart. The cookies will spread and you don’t want them to run together during the baking process.
Bake cookies for about 15 minutes, checking to make sure they are done. You will know that the cookies are done baking when the tops no longer look wet and shiny. If they need more time let them bake for another couple of minutes and then check them again. Oven temperatures can vary so I like to use an oven thermometer to make sure that the temperature is correct. If you do not have an oven thermometer, check on your cookies often, starting around the 13 minute mark.
Once cookies are baked, remove from the oven and let cool on the baking sheet. To make your cookies perfectly round you can set a a large biscuit cutter or large mouthed glass over each cookie and gently swirl it around to even out all of the sides. For each batch of cookies I like to use a separate baking sheet. You do not want to put the raw cookie dough onto a warm sheet from the oven or this can cause your cookies to bake incorrectly.
