Preheat the oven to 200C
Place chocolate and butter in a medium microwavable bowl and heat for 30 seconds (in 10 second increments) and stir together until the chocolate is completely melted
Stir in the cocoa powder and then set this to the side until cool
In a separate, large bowl, add the eggs and sugar and stir using a hand mixer until the colour gets lighter and then add the vanilla extract and salt and mix all until well combined
Stir in the chocolate mixture from earlier and sift the flour in and mix all until well combined
Finally, transfer the batter into a lined baking pan and bake first for 25-35 minutes or until the centre is fully baked
Enjoy 🍫
Optional: decorate with any icing of your choice
