Preheat oven to 180C/160C Fan/375F/Gas mark 4
Line a 8" by 8" square baking tin with baking paper or reusable liner
Put 4 large eggs, 50 grams of cocoa, 225 grams of sugar, flour & butter or baking spread into a large mixing bowl.
Mix for a few minutes with an electric mixer until the mixture pales in colour.
Use a spatula to scrape the mixture from the sides and bottom of the bowl and then mix again.
The mixture should be of a soft dropping consistency so if you were to scoop a dollop up and try to drop it without force off the spoon it should do so easily. If it doesnt then add a splash of milk and mix again. Repeat if required.
Dollop it all out into that lined baking tin enjoying all that fabulous ASMR. Lush.
Smooth it evenly in the tin with the back of a large spoon.
Then bake it baby for about 40 minutes or until the top is springy to the careful touch and a cocktail stick comes out without any mixture stuck to it.
During this time if you are serving the pud straight away then make your custard whilst it goes about it's baking business
Allow to cool for 5 minutes before slicing into the squares that we remember so well.
I use a ruler and knife when cutting my squares because I have the visual perception of a toddler and cannot cope with even a whiff of unevenness as a hostess.
