In a small bowl combine the flour, baking powder, and salt. Set aside.

In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugars on high speed for 2-3 minutes.

Mix in the egg yolk and vanilla until fully combined.

Scrape down the bowl, then add in the dry ingredients and mix on low speed until just combined.

Lastly, fold in the chocolate chips.

Portion the cookie dough with a 2 tablespoon cookie scoop and place them on one small baking sheet lined with parchment paper.

Freeze the cookie dough for 30 minutes.

Meanwhile, preheat the oven to 350 degrees F.

Place the frozen cookie dough on a parchment lined baking sheet spaced about 2 inches apart. Top each with more chocolate chips.

Bake the cookies for about 14-16 minutes until the edges are golden.

Once the cookies are done baking, immediately use a large cookie cutter to push the edges in and shape the cookies into perfect circles.

Allow them to cool completely on the baking sheet.

Top with flaky sea salt and enjoy!
