Pre-heat the oven to 350° F. Line a baking sheet with parchment paper and set aside.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
1½ cups all-purpose flour, ½ tsp baking powder, ½ tsp baking soda, ¾ tsp salt
In a separate large bowl, use an electric mixer to cream the butter and both sugars together until light and fluffy, about 1-2 minutes. Add the vanilla and egg, mixing until combined.
½ cup unsalted butter, ⅓ cup granulated sugar , ½ cup light brown sugar, packed, 2 tsp vanilla extract, 1 large egg
Gradually add in dry ingredients. Mix until everything is combined, but don’t over-mix! Use a rubber spatula to fold in the chocolate chips.
1½ cups semi-sweet chocolate chips
Scoop dough onto the baking sheet with a cookie scoop (I used 2-3 tbsp worth of dough).
Bake for 9-12 minutes, until the edges are lightly golden brown but the middle is still underdone. Press a few extra chocolate chips into the tops of the cookies as soon as they come out of the oven. Let them sit on the pan for about 5 minutes and then transfer to a wire cooling rack, sprinkle with flaky sea salt, and let them cool completely.
