01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together the flour, oats, baking soda, baking powder, salt, ginger, cinnamon, cloves, and nutmeg in a medium bowl. Set aside.
03 - Beat the softened butter, granulated sugar, and brown sugar together until light and fluffy, approximately 2 minutes.
04 - Add the molasses, egg, and vanilla extract to the butter mixture, beating until well combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until incorporated.
06 - Fold in the raisins with a spatula until evenly distributed throughout the dough.
07 - Using a tablespoon or cookie scoop, drop rounded balls of dough onto the prepared baking sheets, spacing about 2 inches apart.
08 - Bake for 11–13 minutes, or until the edges are set and the centers look just slightly underbaked.
09 - Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
