01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, and cardamom. Set aside.
03 - In a large bowl, beat the softened butter with both sugars until light and fluffy, about 2 minutes.
04 - Beat in the eggs one at a time, then stir in the vanilla extract until fully incorporated.
05 - Gradually add the dry ingredients to the wet mixture, mixing until just combined. Do not overmix.
06 - Fold in the rolled oats, raisins, diced apple, and nuts (if using) until evenly distributed throughout the dough.
07 - Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
08 - Bake for 11 to 13 minutes, or until the edges are golden and the centers are just set.
09 - Allow the cookies to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
