Step 1
Mix the butter, oil and sugars before beating in the eggs and vanilla extract.
Step 2
Mix in the flour, cocoa powder and salt, mix into the wet ingredients until just combined, before mixing in the dark chocolate chunks.
Step 3
Pour the batter into a greasde (optionally foil or parchment paper lined), 9×13 inch baking pan and bake in a preheated 350F/180C oven until the top looks just set but still jiggles a little, about 18-22 minutes, before pulling out of the oven and letting it cool in the pan for 30 minutes.
Step 4
Slice and enjoy!
