Preheat your oven to 375 degrees F. Line a few baking sheets with parchment paper.

In a medium bowl, combine flour, baking powder, salt, and apple pie spice. Stir until evenly mixed.

Using an electric mixer, beat the softened butter with the granulated and brown sugars on high speed until light and fluffy, about 3-4 minutes.

Mix in the vanilla extract and eggs one at a time until well combined.

Gradually integrate the dry mixture into the creamed butter on low speed.

Gently fold the oats and raisins into the mixture with a spatula.

Using a 1 ½ tablespoon cookie scoop, portion the dough onto the prepared sheets, spacing them two inches apart.

Bake for 12-14 minutes, until cookies are golden at the edges. Cool for 5 minutes on the baking sheets.
