Pre-heat oven to 350° and line several baking sheets with parchment paper or silpat mats.
In a medium bowl whisk together flour, soda, salt and spices. Set aside.
In the bowl of a stand mixer or with a hand mixer cream the butter and sugars until light and fluffy. Add eggs one at a time, beating after each addition.
Add the flour all at once and mix on low speed just until combined. Add the oats and raisins and mix on low until combined.
Scoop onto prepared baking sheets with a 2 tablespoon cookie scoop or roll into balls; placing 2 inches apart.
Bake in preheated oven 10-12 minutes or until golden brown around the edges. I like my cookies walking the line towards underbaked, so I baked mine 10 minutes. My brother likes them well done, so I baked his 12 minutes.
