Preheat the oven to 400 F. Line 2 large baking sheets with a silicone baking mat or parchment paper.

In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder and salt. Set aside.

Making the Cookie Dough

In the bowl of a stand mixer fitted with the paddle attachment, add the butter, peanut butter, granulated sugar and brown sugar. Mix on medium speed until the butter mixture is thoroughly combined and there are no lumps.

Now add the eggs and vanilla and mix again until fully incorporated. Turn off the mixer and add the flour mixture. Turn the mixer on low at first, so you don’t have a cloud of flour fly into your face. Once the flour begins to turn into a dough, you can turn the mixer speed to medium to fully mix everything together. Along the way you may need to stop the mixer to scrape the sides of the bowl with a rubber spatula so nothing is stuck on the sides.

Once the cookie dough has come together, add the chocolate chips and mix just until combined. Scoop the dough with a spoon or a cookie scoop into whatever size cookies you want to make, leaving around 2-inches of space between each one. Sprinkle a small amount of flakey sea salt on top of each cookie.

Baking and Cooling

If you are making a standard size cookie (around 2 tablespoons of dough), bake the cookies for 8-10 minutes, until the edges begin to turn golden brown. Let rest on the cookie sheet for 5 minutes before transferring them to a wire rack or plate to finish cooling.
