These are like tiny inside-out carrot cakes, with the signature cream cheese frosting on the inside and spiced “cake” on the outside.

　　

Ingredients

makes about 3 dozen

　　1 cup (2 sticks) unsalted butter, room temperature

　　1 cup packed light brown sugar

　　1 cup granulated sugar

　　2 large eggs, room temperature

　　1 teaspoon pure vanilla extract

　　2 cups all-purpose flour, plus more for flattening cookies

　　1 teaspoon baking soda

　　1 teaspoon baking powder

　　1/4 teaspoon salt

　　1 teaspoon ground cinnamon

　　1/2 teaspoon freshly grated nutmeg

　　1/2 teaspoon ground ginger

　　2 cups old-fashioned rolled oats

　　1 1/2 cups finely grated carrots (about 3 large carrots)

　　1 cup raisins

　　Cream Cheese Frosting (recipe follows)

　　

CREAM CHEESE FROSTING

8 ounces cream cheese, room temperature

　　1/2 cup (1 stick) unsalted butter, room temperature

　　1 cup confectioners’ sugar

　　1 teaspoon pure vanilla extract

　　

Step 1

Line two baking sheets with parchment paper. In an electric mixer fitted with the paddle attachment, beat butter and both sugars on medium speed until light and fluffy, 3 to 4 minutes. Add eggs and vanilla, and beat on medium speed until well combined.

　　

Step 2

Sift together flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger; stir to combine. Gradually add flour mixture to butter mixture; mix on low speed until just blended. Mix in oats, carrots, and raisins. Chill until firm, at least 1 hour.

　　

Step 3

Preheat oven to 350°F. Shape tablespoons of dough into balls, and place on prepared baking sheets, spacing 2 inches apart.

　　

Step 4

Bake until browned and crisp, 12 to 15 minutes, rotating halfway through. Transfer to a wire rack to cool completely. Using an offset spatula, spread about 2 teaspoons of frosting onto flat sides of half the cookies. Sandwich together with remaining cookies. Cookies can be refrigerated in airtight containers up to 3 days.
