Method
Preparation
- Preheat your oven to 400°F (200°C). Line two cookie sheets with parchment paper or silicone mats.
- In a medium bowl, whisk together all-purpose flour, cake flour, cornstarch, baking powder, baking soda, and salt. Set aside.
Mix Dough
- In the bowl of a stand mixer, combine cold butter and both sugars. Mix on medium speed until creamy and well blended. Scrape down the sides.
- Add the cold egg and vanilla. Mix just until combined.
- Toss in the chopped chocolate, 1 cup of chocolate chips, and walnuts, then add the flour mixture. Mix on low speed until the flour is just incorporated.
Bake
- Use a large 1/2 cup cookie scoop to divide the dough into 10 equal balls. Press the remaining chocolate chips on top.
- Bake for 12 to 13 minutes until the edges and bottoms turn golden brown. If desired, sprinkle some sea salt on top.
- Let them cool on the sheets for 5 minutes, then transfer cookies to a wire rack to cool completely.
Notes
Chill dough for an hour for thicker cookies. Suitable for freezing up to 3 months.
