Preheat your oven to 350°F (175°C).
Line your baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Mix in the peanut butter until well combined, then add the eggs one at a time, followed by the vanilla extract.
Gradually add the flour mixture to the wet ingredients, mixing just until combined.
Gently fold in the crushed peanuts.
Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheets, leaving space for spreading.
Bake for 10-12 minutes, or until the edges are lightly golden.
Allow cookies to cool on the baking sheets for 5 minutes before transferring to a cooling rack.
