Method
1. Toast the Pecans
Place the chopped pecans in a dry skillet over medium heat. Toast them, stirring frequently, until they become fragrant and slightly darker in color (about 3–5 minutes). Remove from the pan and set aside to cool completely.2. Brown the Butter
Melt the unsalted butter in a saucepan over medium heat. Continue to cook, swirling the pan constantly. The butter will foam and sizzle before eventually turning a deep amber color with a toasted, nutty aroma. Immediately pour the browned butter (including all the brown specks at the bottom) into a large heat-proof bowl. Let it cool for 10 minutes.3. Mix the Wet Ingredients
To the cooled browned butter, add the dark brown sugar and white granulated sugar. Whisk vigorously until well combined and no lumps remain. Whisk in the room-temperature eggs one at a time until fully incorporated, then stir in the vanilla extract.4. Combine the Dry Ingredients
In a separate medium bowl, sift together the all-purpose flour, cornstarch, baking soda, and fine sea salt.5. Form the Cookie Dough
Gently fold the sifted dry ingredients into the wet mixture using a rubber spatula. Stop mixing when there are just a few streaks of flour left. Fold in the toasted pecans and chocolate chips until evenly distributed. (Do not overmix!)6. Chill the Dough
Scoop the dough into large, even balls and place them on a tray. Cover tightly and chill in the refrigerator for at least 2 hours. (Do not skip this step, or your cookies will spread and flatten in the oven!)7. Preheat and Prep
When ready to bake, preheat your oven to 175°C (350°F). Line your baking sheets with parchment paper.8. Bake
Place the chilled cookie dough balls onto the prepared baking sheets, leaving about 5 cm (2 inches) of space between each cookie. Bake for 11 to 13 minutes. The cookies are done when the edges are set and golden brown, but the centers still look very soft and slightly underbaked.9. Cool and Serve
Remove from the oven and let the cookies rest on the hot baking sheet for 5 minutes to firm up. Transfer them to a wire rack to cool completely. Enjoy with a cold glass of milk!
Notes
- Weighing Ingredients: For the absolute best, bakery-style results, use a digital kitchen scale to measure your ingredients in grams.
- Make-Ahead: You can leave the scooped cookie dough balls in the fridge for up to 48 hours before baking. This actually deepens the toffee flavor!
-
Storage: Store leftover baked cookies in an airtight container at room temperature for up to 5 days. Warm in the microwave for 10 seconds to make them gooey again.Always let your browned butter cool for at least 10 minutes before adding your sugars and eggs to prevent the butter from melting the sugar or scrambling your eggs!
