In the bowl of a stand mixer, use the paddle attachment and mix the butter until creamy.
Add the brown sugar and granulated sugar and mix until fluffy, about 2 minutes.
Mix in the egg yolk until fully incorporated.
Then, mix in the vanilla extract.
In a separate bowl, whisk together the flour, salt, baking soda, cinnamon, nutmeg and cardamom.
Set the mixer on low speed, and slowly add the flour mixture into the butter mixture.
Stir in the oats and raisins just until mixed in.
Scoop out the dough using a cookie scoop and place them onto the prepared cookie sheet, leaving at least 2 inches between each cookie.
Bake about 12 - 15 minutes until cookie edges turn golden brown.
Cool on the baking sheet about 2 minutes, and then cool completely on a wire rack.
