Preheat oven to 350 F (180 C), line baking sheets with parchment paper.
In stand mixer, cream butter and sugars until fluffy. Add eggs and vanilla extract, beat until everything is fully incorporated and smooth.
In a large bowl, mix together flour, baking soda, spices, and salt.
Slowly add this dry mix to the mixer bowl, and carefully mix until well incorporated and smooth. Add oats and raisins, continue mixing just until well incorporated.
Roll 1" balls out of the cookie dough, arrange dough balls on baking sheets. Leave at least 2" between cookies - they flatten out a fair amount.
Gently press the tops of each slightly - flatten JUST enough to prevent the dough from rolling.
Bake for 11-13 minutes. Cookies will look puffy, but flatten out as they cool. Do not over bake!
Allow cookies to cool for 2 minutes before removing from baking sheets.
Cool completely before storing in an airtight container
