Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
In a separate bowl, whisk together the rolled oats, flour, cinnamon, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Stir in the raisins.
Press the dough evenly into the prepared baking pan.
Bake for 23-27 minutes, or until golden brown.
Let cool completely in the pan before lifting out using the parchment paper and cutting into bars.
