Step 1

In a large mixing bowl, combine the flour, both sugars, salt, baking powder, baking soda, and chopped chocolate or chocolate chips.

Step 2

Pour in the melted butter, egg, and vanilla extract and mix just until the dough comes together. Be careful not to over-mix as that will overwork the gluten.

Step 3

Cover and refrigerate the cookie dough for at least 30 minutes before baking.

Step 4

Preheat the oven to 350 degrees Fahrenheit.

Step 5

Use a cookie scoop to scoop the dough onto a parchment paper-lined baking sheet, leaving at least 2 inches between cookies.

Step 6

Sprinkle each cookie with some of the flaky salt.

Step 7

Bake for 12 minutes, or until the edges have just started to brown.

Step 8

Allow the cookies to set on the sheet pan for a couple of minutes before moving them to a wire rack to cool completely.
