Preheat oven to 365ºF or 185ºC. Line 2 large baking sheets with parchment paper or silicone baking mats. Set aside.
Whisk together dry ingredients: flour, baking powder, baking soda, and salt. Set aside.
Add softened butter and sugars to a large mixing bowl and use an electric mixer to beat together on medium speed until combined and creamy, about 2 minutes. Add eggs one at a time, mixing after each addition until just combined. With the last egg, add in vanilla extract.
On low speed, gradually add the dry ingredients to the butter/sugar mixture.
On low speed, beat in the chocolate chips.
Drop balls of cookie dough onto the lined cookie sheet. I used 40 grams (about 2 tablespoons) of dough for each cookie. This will make medium-sized cookies, like the ones pictured.
Bake for 10-12 mins. Remove from the oven right when edges start getting golden.
If desired, while the cookies are still warm, press a few extra chocolate chips into the tops and sprinkle with coarse sea salt. Cool for 5 minutes on the baking sheet. Transfer cookies to a cooling rack to cool completely. Cookies stay fresh covered at room temperature for up to 1 week.
