Step 1

Preheat the oven to 350 degrees. Grease a baking sheet with nonstick cooking spray and set aside.

Step 2

In a medium bowl, whisk together the flour, baking powder, baking soda,  salt, cinnamon, and nutmeg. Set aside.

Step 3

In a large bowl, cream together the butter, dark brown sugar, and granulated sugar.  Mix in the eggs and vanilla.

Step 4

Add the flour mixture into the wet mixture and stir until just combined (be careful not to overmix).

Step 5

Stir in the oats and then fold in the raisins.

Step 6

Using a cookie scoop or spoon, add scoops of about 1.5 tablespoons cookie dough to the prepared cookie sheet. The cookies should be about 2-in. apart.

Step 7

Bake for 12-13 minutes in the preheated oven. The cookies should be evenly golden brown on top with cracks that are soft. Let the cookies cool for 2 - 3 minutes before transferring to a wire rack to cool completely.
