Preheat the oven to 350 degrees F. Like a baking sheet with parchment paper.

Add 1/2 cup water to the pecans and raisins, then microwave for 90 seconds. Allow the raisins and pecans to sit on the counter for about 10 minutes. Drain the raisins and pecans and set aside.

In a large bowl, combine the butter and the sugars and beat with an electric mixer until very creamy. Add the vanilla extract and eggs, and beat again until mixed.

In a small bowl, sift together the flour, baking soda, cinnamon and salt. Add it to the butter mixture. Add the oats, raisins and pecans. Mix together.

Drop heaping tablespoons of batter onto the prepared baking sheet. Leave plenty of room for the cookies to spread. Bake until the cookies are cooked in the middle, 10 to 12 minutes. Remove the cookies from the oven. Cool on the baking sheet for about 3 minutes before transferring to a wire rack to cool completely.
