Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a mixing bowl, combine the gluten-free rolled oats, gluten-free flour, baking soda, cinnamon, and salt.
In another bowl, beat the softened butter, brown sugar, and granulated sugar until creamy. Add the eggs and vanilla extract, and mix well.
Gradually add the dry ingredients to the wet ingredients, mixing until well combined. Stir in the raisins.
Drop spoonfuls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are golden brown. Let the cookies cool on the baking sheet for a few minutes before transferring them to a cooling rack to cool completely.
