Salted Dark Chocolate Cookies

Preliminary note

This cookie dough requires at least 3 hours of chilling, but I prefer to chill the dough overnight. The colder the dough, the thicker the cookies.

In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter, granulated sugar, and brown sugar together on medium high speed until fluffy and light in color, about 2-3 minutes. Add the egg and vanilla extract, and then beat on high speed until combined. Scrape down the sides and bottom of the bowl as needed.

In a separate bowl, whisk the flour, both cocoa powders, baking soda and salt together until combined. With the mixer running on low speed, slowly pour into the wet ingredients. Beat on low until combined. The cookie dough will be quite thick. Switch to high speed and beat in the milk, then the chocolate chips. The cookie dough will be sticky and tacky. Cover dough tightly and chill in the refrigerator for at least 3 hours and up to 3 days. Chilling is mandatory for this sticky cookie dough.

Remove cookie dough from the refrigerator and allow to sit at room temperature for 10 minutes. If the cookie dough chilled longer than 3 hours, let it sit at room temperature for about 20 minutes. This makes the chilled cookie dough easier to scoop and roll.

Preheat oven to 350°F (177°C). Line large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.

Scoop and roll dough, a heaping 1.5 Tablespoons of dough each, into balls (I like to use this medium cookie scoop). To ensure a thicker cookie, make the balls taller than they are wide (almost like a cylinder or column). Arrange 2-3 inches apart on the baking sheets. Sprinkle each with sea salt. The cookie dough is certainly sticky, so wipe your hands clean after every few balls of dough you shape.

Bake the cookies for 11-12 minutes or until the edges appear set and the centers still look soft. Tip: If they aren’t really spreading by minute 9, remove them from the oven and lightly bang the baking sheet on the counter 2-3x. This helps initiate that spread. Return to the oven to continue baking.

Cool cookies for 5 minutes on the baking sheet. During this time, I like to press a few more chocolate chips into the tops of the warm cookies or sprinkle with more sea salt. (This is optional.) Transfer to cooling rack to cool completely. The cookies will slightly deflate as they cool.

Cover leftover cookies tightly and store at room temperature for up to 1 week.
