Preheat oven to 350 degrees. Line two baking sheets with parchment paper or nonstick baking pads and set aside.
In a large bowl, beat together butter and sugars for about two minutes, until fluffy. Beat in egg, egg yolk, and vanilla. In a seperate bowl, whisk together the flour, cinnamon, baking soda, and salt. Stir into wet mixture until combined. Fold in oats and raisins.
Use a cookie scoop to roll into balls. Place on to the lined baking pan about two inches apart. Bake for about 12-14 minutes, until golden, rotating the pan halfway through baking. Cool on pans for 5 minutes before transfering to wire racks to cool completely.
