Preheat the oven to 350 degrees. Line two cookie sheets with parchment and set aside for later use.

Combine the butter and chocolate chips in a microwave safe bowl. Heat in 30 second intervals, stirring in between, until melted. Set aside.

Add your eggs, sugar, and vanilla into the bowl of an electric mixer. Beat with the paddle attachment 3-4 minutes or until fully combined. Slowly stir in the melted chocolate mixture.

In a small bowl combine the cocoa, salt, baking powder, and flour. Fold into your batter.

Drop spoonfuls onto your prepared sheets. Sprinkle each cookie dough ball with fleur de sel.

Bake 10-12 minutes.
