INGREDIENTS
1 1/2 cups
all-purpose flour - I use King Arthur's unbleached all-purpose
1 tsp
baking powder
1/2 tsp
kosher salt
1/4 tsp
baking soda
1 stick
unsalted butter, at room temperature
3/4 cup
packed dark brown sugar (dark brown sugar adds more flavor) - Use fresh, moist brown sugar instead of hardened brown sugar, which will make the cookies dry. The original recipe called for light brown sugar, but I really prefer dark brown sugar.
1/2 cup
granulated sugar
1/4 cup
powdered/confectioners sugar
2
large egg yolks
1
large egg
1 tsp
vanilla extract
8
-ounces bittersweet or semisweet chocolate, coarsely chopped - I used two 4-ounce bars of Ghirardelli 60% bittersweet chocolate
Maldon or flaky sea salt crystals- I used Baleine coarse sea salt crystals
