Step 1

To prepare cookies: Preheat oven to 350 degrees F. Lightly coat a baking sheet with cooking spray.

Step 2

Whisk flour, baking powder, pumpkin pie spice and salt together in a medium bowl.

Step 3

Whisk brown sugar, butter, egg and vanilla together in a large bowl. Add the flour mixture, oats, carrots and raisins and stir with a wooden spoon until well combined. Drop level tablespoons of batter onto the prepared baking sheet, making 12 cookies per batch.

Step 4

Bake until the cookies are golden brown on the bottom, 12 to 14 minutes. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. Repeat with the remaining batter.

Step 5

To prepare cream cheese glaze: If desired, combine cream cheese, confectioners' sugar and 1 tablespoon milk in a mini food processor; process until smooth, adding up to 1 tablespoon more milk, if needed, to achieve a thick glaze consistency. Drizzle the glaze over the cooled cookies.
