These are the best chocolate brownies you'll ever have! They're moist, gooey, fudgy, and totally out of this world.
Preheat the oven to 350 degrees Fahrenheit. Grease an 8x8-inch baking pan or line with parchment paper.
In a large bowl, whisk together the melted butter and sugar. Beat in the eggs, one at a time, then stir in the vanilla.
Sift in the cocoa powder, flour, cornstarch, and salt. Mix the ingredients with a rubber spatula until smooth and well combined. Then, fold in the chopped chocolate.
Spread the batter evenly into the prepared baking pan, and smooth. Bake the brownies for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached.
Allow the brownies to cool for at least 30 minutes before cutting into squares. Sprinkle them with sea salt flakes if using. Serve and enjoy!
