Preheat your oven to 350°F (175°C).

In a large mixing bowl, cream the unsalted butter, granulated sugar, and brown sugar until light and fluffy.

Add the large eggs one at a time and mix in the vanilla extract.

Whisk together the flour, baking powder, and salt in a separate bowl. Gradually combine with the wet ingredients.

Fold in the chopped pecans.

Drop spoonfuls of the dough onto a baking sheet lined with parchment paper and bake for 10 to 12 minutes.

Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
