Cream Butter and Sugars: Beat the softened butter, granulated sugar, and brown sugar for 2–3 minutes until lighter and fluffy.
⅔ cup unsalted butter, ½ cup granulated sugar, ¼ cup packed brown sugar
Add Egg and Vanilla: Mix in the egg and 1 teaspoon vanilla until smooth and fully combined.
1 large egg, 1 teaspoon vanilla extract
Fold in Dry Ingredients: Add the flour, cinnamon, baking soda, and salt, then gently fold with a spatula just until you don’t see dry flour. Stop there so the cookies stay soft.
1 ½ cups all-purpose flour, 1 teaspoon ground cinnamon, 1 teaspoon baking soda, 1 teaspoon salt
Add the Carrots: Fold in the shredded carrots until evenly mixed through the dough.
1 cup finely shredded carrots
Scoop and Chill: Line baking sheets with parchment paper. Scoop 10 equal dough balls and space them out (about 5 per sheet). Chill for 1 hour so the cookies don’t spread into flat pancakes.
Bake: Heat the oven to 350°F. Bake for 16–18 minutes, until the edges look lightly golden and the centers still look soft.
Cool Completely: Let cookies sit on the pan for 5 minutes, then move to a wire rack. Do not frost until fully cool.
Make the Frosting: Beat cold cream cheese, cold mascarpone, powdered sugar, and ¼ teaspoon vanilla just until fluffy and thick. Stop once it holds shape, because overmixing can turn it runny.
8.1 ounces full-fat cream cheese, 2.6 ounces mascarpone, 1.8 ounces powdered sugar, ¼ teaspoon vanilla extract
Frost the Cookies: Reserve about ½ cup frosting for decorations. Spread the remaining frosting over cooled cookies.
Decorate: Tint the reserved frosting orange and green with gel coloring, transfer to piping bags, and pipe small carrot shapes on top.

Store: Keep in an airtight container in the fridge for 1–2 days. For best texture, let them sit at room temp for 10–15 minutes before eating.
