Step 1

Preheat oven to 350F. Lightly coat a baking sheet with cooking spray.

Step 2

Whisk flour, baking powder, cinnamon and salt in a medium bowl.

Step 3

Whisk sugar, butter, egg and vanilla in a large bowl. Add flour mixture, oats 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 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.
