Preheat your oven to 350°F (175°C).

In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar until creamy.

Add the eggs one at a time, followed by the vanilla extract, mixing until well combined.

In another bowl, whisk together the quick oats, flour, baking soda, cinnamon, and salt.

Gradually add the dry mixture to the wet ingredients, stirring until just combined.

Carefully fold in the raisins using a spatula.

Using a cookie scoop or tablespoon, drop dough onto a lined baking sheet about 2 inches apart.

Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown.
