Preheat oven to 350°F and line baking sheets with parchment paper.

Beat butter and both sugars until fluffy, then add eggs and vanilla.

Whisk together flour, baking soda, cinnamon, and salt, then stir into butter mixture.

Fold in oats and drained raisins until evenly distributed.

Scoop dough into 2-tablespoon balls and place 2 inches apart on prepared sheets.

Bake 10-12 minutes until edges are set but centers are still soft.

Cool on pan 5 minutes before transferring.
