Step 1

Preheat your oven to 180C/160C Fan and line a 9″ Square baking tray with parchment paper.

Step 2

Melt together the Butter, and Dark Chocolate in a heatproof bowl over a pan of boiling water, on the microwave for 1-2 minutes until melted. Leave to the side to cool to room temperature!

Step 3

Using an electric whisk/stand mixer, whisk together the Eggs & Caster Sugar for a few minutes until the colour has turned pale, is very mousse like, and is double the original volume of the amount of eggs + sugar!

Step 4

You will know its done because when you lift the whisk up out of the mix it should leave a trail for a couple of seconds before disappearing!

Step 5

When whisked, pour the cooled chocolate mix over eggs and fold together carefully. It might take some time, but be patient – you don’t want to knock out the air you made up on the previous step!

Step 6

Once completely combined, sift the cocoa powder and plain flour on top of the chocolate mix and then fold together again – still be careful to not knock out the air!

Step 7

Once combined well, fold through the chocolate chips and pour into the prepared tin – bake in the oven for 25-30 minutes! Once baked, leave to cool in the tin completely.
