Step 1

Start by pre-heating your oven to 180c/350f. Also grease and line a 9x12 inch cake tin.

Step 2

In a pot, add the butter and dark chocolate. Place this over medium heat and heat until melted and smooth. You could also just do this in your microwave. Leave this aside to cool.

Step 3

In a large bowl, add in your eggs and both sugars. Whip these together using an electric mixer, or a whisk, until the mixture has lightened in colour and almost doubled in volume.

Step 4

Pour the cooled melted butter and chocolate into this and whisk.

Step 5

Now add in the flour, cocoa powder and salt. Whisk just until you get a smooth batter.

Step 6

Pour this into your prepared cake tin and bake for around 35-40 minutes, or until a toothpick inserted into the centre comes out with a few moist crumbs on it.

Step 7

In a non stick pot that has high sides, add about a 1/4 of the sugar. Place this pot over medium heat.

Step 8

Keep heating this, whiles constantly stirring, until the sugar starts to melt slightly. Add another 1/4 of the sugar and heat again, until this sugar starts to melt too. Keep repeating this until all the sugar has been added to the pot. Make sure to be constantly stirring during this process.

Step 9

Once all the sugar has been added, keep stirring until all of the sugar has completely melted and turned into a deep amber colour.

Step 10

Immediately take this off the heat, then add in half of the butter. Mix this in, then add the rest of the butter. Mix until smooth. Now slowly pour in the cream, whiles mixing.

Step 11

Place this caramel back onto medium heat and let it cook, for about 2 minutes. This is just to thicken it slightly.

Step 12

Take if off the heat, mix in the salt and then the cornflakes.

Step 13

Once your brownie has baked and cooled down for about 10 minutes, add the cornflake layer on top and smooth it out.

Step 14

Leave this in the fridge for at least 2 hours to set, I prefer to just leave it overnight but 2 hours will be fine.

Step 15

Once set, take it out of the tin, cut it into slices and then enjoy!
