Preheat an oven to 350°F and line a baking sheet with parchment paper.
In a medium bowl combine the flour, oats, baking soda, salt, cinnamon and raisins. Set aside until needed.
In the bowl of a mixer combine the softened butter, granulated sugar and brown sugar. Cream until light and fluffy. About 3 minutes.
Add the eggs in, one at a time, scraping down the bowl as needed. Mix until fully combined. Add in the vanilla and mix well.
Stir in the dry ingredients until fully combined. Using a 1-ounce portion scoop or 2 rounded tablespoons, drop the cookies on the prepared baking sheet, leaving about 2-inches between each cookie. Gently press down on each cookie ball to slightly flatten them.
Place in the oven and bake for 12 minutes. Allow to cool for a few minutes on the baking sheet before transferring to a cooling rack to finish cooling. Enjoy!
