Preheat oven to 350°F and line 2 baking sheets with parchment paper.
In a medium bowl, combine flour, sifted match powder, baking soda, and salt. Set aside.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, combine butter and sugars, beating until light and fluffy (around 1-2 minutes).
Add in egg and vanilla, then beat until just combined (do not over-mix!).
Slowly add in the dry ingredients and mix until a dough forms. Stir in the chocolate chips.
Use a medium cookie scoop or spoon to make 1.5-2 tablespoon sized balls and place them on the baking sheet.
Bake the cookies (one baking sheet at a time, for even baking) for 8-11 minutes. Remove them from the oven when the edges look set. They will look slightly under-baked in the middle and should not be golden brown!
Remove from the oven and leave them on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Enjoy!
