By gapboy1379-2

Ingredients

• 1 1/2 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon kosher salt
• 1/4 teaspoon baking soda
• 1/2 cup (1 stick) unsalted butter, room temperature
• 3/4 cup (packed) light brown sugar
• 1/2 cup sugar
• 1/4 cup powdered sugar
• 2 large egg yolks
• 1 large egg
• 1 teaspoon vanilla extract
• 8 ounces semisweet or bittersweet chocolate (do not exceed 72% cacao), coarsely chopped
• Maldon or other flaky sea salt

Preparation

Step 1

Place racks in upper and lower thirds of oven and preheat to 375°. Whisk flour, baking powder, kosher salt, and baking soda in a medium bowl; set aside.

Using an electric mixer on medium speed, beat butter, brown sugar, sugar, and powdered sugar until light and fluffy, 3-4 minutes. Add egg yolks, egg, and vanilla. Beat, occasionally scraping down the sides of the bowl, until mixture is pale and fluffy, 4-5 minutes. Reduce mixer speed to low; slowly add dry ingredients, mixing just to blend. Using a spatula, fold in chocolate.

Spoon rounded tablespoonfuls of cookie dough onto 2 parchment paper-lined baking sheets, spacing 1-inch apart. Sprinkle cookies with sea salt.
Bake cookies, rotating sheets halfway through, until just golden brown around the edges, 10-12 minutes (the cookies will firm up as they cool).

Let cool slightly on baking sheets, then transfer to wire racks; let cool completely. DO AHEAD: Cookies can be made 1 day ahead. Store airtight at room temperature.
