Measure all ingredients and bring butter and peanut butter to room temperature.
In a large bowl, beat together the peanut butter, butter, granulated sugar, and brown sugar for exactly 3 minutes on medium-high speed until light and fluffy.
Beat in the egg and vanilla extract until fully incorporated, about 1 minute.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Cover the dough and refrigerate for 30 minutes.
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Roll tablespoon-sized dough portions into balls, then roll in additional granulated sugar. Place on the prepared baking sheets about 2 inches apart.
Create the iconic crosshatch pattern by pressing with a fork in perpendicular directions.
Bake for 12-14 minutes, or until the edges are golden brown. For extra-crispy cookies, add 1-2 minutes to the baking time, watching carefully to prevent burning.
Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
