School Style Chocolate Concrete

It’s the ultimate comfort pudding. We all had it at school (usually with pink custard) – Chocolate concrete is having a revival! Every sandwich shop I go in lately has it in the cake display but in my household it’s never really gone away.

My mother used to be a dinner lady when I was a girl and when she left, one of the cooks gave her the recipe as a leaving present. It feels a little naughty to share it actually. As if I’m breaking some kind of ‘dinner lady code’. But here it is. And its amazing! Perfect hearty pudding for after a weekend roast. Sundays will never be the same again.

Pre heat oven to Gas Mark 4 or 180c

80z Self Raising Flour

1oz Cocoa powder

6oz caster sugar

6oz butter

1 egg

Melt the butter in a pan. Place flour, sugar and cocoa powder in a bowl and mix together. Add the melted butter and the egg to the dry ingredients and combine. Grease a tray bake or swiss roll tin (approx 1inch deep). Put the mixture in the tin and pat it down until level and even. Bake for 15 mins if you like it soft. If you prefer it like real chocolate concrete bake for 15 mins, then turn the oven right down and leave it on the bottom shelf for another 15-30 mins depending on how crunchy you want it! Sprinkle with a little caster sugar while still warm.

Slather with custard and curl up on the sofa.

Freezes well.

  2. The original recipie also had coconut in , I was a school cook for yrs n it’s on sch menus today but it’s called chocolate crunch ! Served with chocolate sauce and the kids go mad for it xx

  3. 1we called it chocolate crunch and served it with chocolate custard. Used to make it a lot for my children. Cheap and easy. Love it

  4. I was a school cook also we used to ask the children what they wanted for pudding on the xmas lunch day and this was always the one they chose, we always served it with pink custard ,i always have to make this for bonfire night for friends and family and it flies out the tin, however our school recipe is different and we use a secret technique to make it hard and its not longer cooking time lol

    • How do you make pink custard? I have a friend that has been on the search for this for years.. Please could you give me the recipe? X

  5. Mine has just gone like cake. Mixture was like cake batter/rinny is that right. What temp do you put it on when you turn oven right down

  6. Here’s one for you I can remember having this with jungle juice, but gos knows what it was…. Possibly a really runny warm jam???
    Any ideas please? Ben

  7. I Just made this chocolate crush , but miss read the ingredients & put in 10 oz of coco powder, it’s vile as you can imagine , I certainly no cook lol

    • I read it as 10oz first as well but as I have done lots of cooking realised it must only be 1oz needs a space between the 1 an the oz. Have just cooked it an it’s yummy
