Carrot Cake Sandwich Cookies

Carrot Cake Sandwich Cookies
Makes about 25 sandwiches

1 cup packed brown sugar
1 cup sugar
1/2 pound (2 sticks) unsalted butter, room temperature
2 eggs, room temperature
1 teaspoon vanilla extract
2 cups flour
1 teaspoon baking soda
1 teaspoon baking powder
1/4 teaspoon salt
1 teaspoon cinnamon
1/2 teaspoon nutmeg
1/2 teaspoon ginger
2 cups rolled oats
1 1/2 cups finely grated carrots, (about 3 large carrots)
1 cup raisins
Cream Cheese Frosting


Preheat oven to 350 degrees. Line two baking sheets with Silpat baking mats or parchment paper, and set aside. In the bowl of an electric mixer fitted with the paddle attachment, combine sugars and butter; beat until light and fluffy, 3 to 4 minutes. Add eggs and vanilla, and beat on medium speed until well combined.
In a large bowl, sift together flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger; stir to combine. Gradually add flour to butter mixture; mix on a low speed until just blended. Mix in oats, carrots, and raisins. Chill dough in refrigerator until firm, at least 1 hour.
Using a 1/2-ounce ice-cream scoop, scoop dough onto prepared baking sheets, leaving 2 inches between cookies. Transfer to oven, and bake until browned and crisped, rotating pan halfway through baking to ensure even color, 12 to 15 minutes. Transfer to a wire rack to cool. Repeat baking process with remaining dough. Once cooled completely, use an offset spatula to spread about 2 teaspoons of cream-cheese filling onto a cookie. Sandwich together with a second cookie. Repeat with remaining cookies. Store in an airtight container for up to 3 days in the refrigerator.
