Preheat oven to 375°F (190°C) and line baking sheets with parchment paper or silicone mats.
In a medium bowl, whisk together flour, baking powder, salt, cinnamon, and nutmeg.
In a large bowl, beat softened butter with granulated and brown sugar until light and fluffy.
Add vanilla extract and eggs, one at a time, mixing well after each addition. Scrape down the bowl as needed.
Gradually mix in dry ingredients until just combined.
Stir in oats until dough becomes thick and cohesive.
Fold in raisins.
Scoop tablespoon-sized portions of dough and place 2 inches apart on prepared baking sheets.
Bake for 12–15 minutes, or until edges are lightly golden.
Let cookies cool on the pan for a few minutes before transferring to a wire rack to cool completely.

Use room temperature eggs and butter for easier mixing. Chill dough optionally for thicker cookies.
