Melt the butter in a microwave-safe bowl.

Add the brown sugar, egg and vanilla extract and whisk until well combined.
Sift the plain flour, cocoa powder, salt and bi-carb soda over the top. Stir until just combined.
Add ½ cup dark chocolate melts and stir through until well combined.
Pour mixture into the prepared loaf tin. Sprinkle the chocolate chips over the top.
Bake for 55 minutes or until a skewer inserted into the middle comes out with just a few crumbs on it (don't overcook though - you want a moist, fudgy loaf).
