Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine softened butter, peanut butter, brown sugar, granulated sugar, and vanilla extract. Beat on medium speed until light and fluffy, about 2-3 minutes.

Add the eggs one at a time, mixing well after each addition.

In a separate bowl, whisk together flour, baking soda, baking powder, and kosher salt. Gradually fold into the wet mixture until just combined.

Using a cookie scoop, portion the dough and roll into balls, then roll in granulated sugar.

Place on an ungreased baking sheet with space between each ball. Flatten with a fork to create a criss-cross pattern.

Bake for 10-15 minutes until edges are golden and centers are set.

Cool on the baking sheet for 2 minutes before transferring to a wire rack.
