Mix Dry Ingredients: In a large bowl, whisk together the bread flour, baking powder, baking soda, and salt. Set aside.
Prepare Butter and Sugars: In the bowl of a stand mixer fitted with the paddle attachment, beat the cold butter until starting to break apart, about 30 seconds. Add the brown and granulated sugars. Mix just until incorporated but still crumbly. Add the eggs and vanilla, mixing on medium-low speed until slightly separated, about 30 seconds.
Combine and Mix Dough: Turn off the mixer and add the dry ingredients. Mix on low speed just until the dough comes together, with some streaks of butter visible. Fold in the chopped chocolates by hand using a rubber spatula.
Shape and Freeze Dough: Drop the dough into heaping 1/2 cup mounds (about 120g/ball) onto 2 parchment-lined sheet trays. You should end up with 11 cookies. Freeze for 1 hour.
Bake: Preheat the oven to 375 degrees F. Bake the cookies directly from the freezer for about 19 to 22 minutes, rotating the tray halfway through, until slightly underbaked in the middle but golden brown around the edges. Smack the tray on the counter and cool the cookies on the tray for 5 minutes before transferring to a wire rack to cool completely.
