Ingredients:
- 415g all-purpose flour
- 10g cornstarch
- 5g baking soda
- 4g sea salt
- 225g cold unsalted butter, cubed
- 165g dark brown sugar, packed
- 100g granulated sugar
- 2 count large eggs, cold
- 10ml vanilla bean paste or extract
- 340g semi-sweet chocolate chips or chunks
- 1 pinch flaky sea salt
Instructions:
- Prepare the butter and sugars. Place the cold, cubed butter, dark brown sugar, and granulated sugar into your mixer bowl. Beat on medium speed for about 2 minutes. Note: You are looking for a sandy paste where you can still see tiny bits of butter.
- Incorporate the liquids. Add the cold eggs one at a time while the mixer is on low. Pour in the vanilla bean paste. Mix only until the yellow of the egg disappears.
- Sift the dry base. Over a separate bowl, sift the flour, cornstarch, baking soda, and sea salt. This ensures no clumps of soda or starch end up in a single bite.
- Combine the mixtures. Slowly add the dry ingredients to the butter mixture. Stop the mixer the second you no longer see white streaks of flour.
- Add the chocolate. Fold in the 340g of semi sweet chocolate chunks by hand using a sturdy spatula. Ensure the chocolate is distributed evenly so every cookie has plenty of molten pockets.
- Portion the dough. Use a scale to divide the dough into six portions, each weighing roughly 170g (6 ounces). Lightly shape them into tall, rough spheres — don't make them too smooth.
- Apply the blast chill. Place the dough balls on a tray and put them in the freezer for 10 to 15 minutes. Note: This shocks the fat, ensuring it stays solid during the first few minutes of baking.
- Execute the bake. Place the chilled dough balls onto a parchment lined baking sheet, leaving at least 3 inches between them. Bake at 200°C for 18 minutes until the edges are mahogany and the tops look dry.
- Finish and rest. Remove from the oven and immediately sprinkle with flaky sea salt. Let them rest on the pan for 15 minutes before moving them; they need this time to set their molten centers.
