Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.

In a mixing bowl, whisk together the flour, baking soda, and salt. Set aside.

In another bowl, combine the peanut butter, brown sugar, and granulated sugar. Beat with an electric mixer until smooth.

Add the egg and vanilla extract, and mix until fully incorporated.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Fold in the chocolate chips using a spatula.

Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.

Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
