Preheat oven to 350 °F, line an 8x4” baking dish with parchment paper and lightly grease, set aside.

Melt chocolate and butter in a microwave safe bowl, or on the stovetop over low heat. Stir until smooth and glossy. Set aside.

In a medium bowl, whisk the egg for 1 minute.

Then, add the granulated sugar and whisk for an additional 1 minute, or until the mixture is pale and thick.

Next, add the melted chocolate/butter mixture and vanilla and whisk to combine.

Add flour, cocoa powder and sea salt to the wet ingredients and whisk or stir with a spatula until the batter is smooth.

Stir in chocolate chips and spread the batter evenly in the bottom of the prepared pan.

Bake in the preheated oven until the top is set and the brownies are only very slightly “jiggly”, 15-18 minutes.

Remove the brownies from the oven and place them on a wire rack to cool completely.

Use the parchment paper to lift the brownies out of the pan onto a cutting board, then into 8 pieces and serve. (cut in half lengthwise, then in half widthwise and cut each half in half widthwise again)
