Combine dry and wet: In a large mixing bowl, pour the entire box of carrot cake mix, then add the 2 eggs and 1/2 cup vegetable oil. Mix on medium speed with an electric mixer for about 2 minutes until the dough comes together and no streaks of dry mix remain.
Add custom mix-ins: If using any optional mix-ins like nuts, raisins, or coconut, fold them in gently with a spatula until evenly distributed throughout the dough.
Prepare your baking surface: Preheat your oven to 350 degrees Fahrenheit and line two baking sheets with parchment paper or silicone baking mats.
Scoop the dough: Using a cookie scoop or two tablespoons, drop rounded portions of dough onto your prepared baking sheets, spacing them about 2 inches apart as they will spread slightly during baking.
Bake: Place both sheets in the preheated 350-degree oven for 12 to 14 minutes, until the edges are set but the centers still look slightly underdone and soft to the touch.
Cool on pans: Allow the cookies to rest on the baking sheets for 5 minutes, which helps them firm up and stay intact when transferred, then move them to a wire cooling rack for 10 additional minutes.
Prepare the frosting: Let the cream cheese frosting come to room temperature for about 5 minutes so it spreads smoothly without tearing the delicate cookies.
Spread or swirl: Once the cookies are completely cooled, spread a generous tablespoon of frosting on top of each cookie, or pipe it in a decorative swirl using a pastry bag fitted with a star tip.
Add final toppings: If desired, immediately sprinkle with extra chopped nuts, coconut flakes, or a light dusting of cinnamon while the frosting is still soft, creating a bakery-quality finish.
