Vegan School Dinners Traditional Chocolate Concrete Cake

Vegan school dinners chocolate concrete cake is a nostalgic throwback to the British old-school dinners puddings of the 1970s, 80s and 90s.

Chocolate concrete cake is so easy and simple.

My vegan chocolate concrete cake recipe results in a cake-biscuit that is hard at the edges but firm chocolate-brownie like inner texture.vegan school dinners chocolate concrete cake

So tasty!

You can soften the edges up by dipping in a cup of tea or coffee!

British school dinner cooks traditionally served chocolate concrete cake with a dollop of custard which would have softened up the edges.

However my kids enjoy clanking the concrete cake off their plate to hear the clunk clunk sound!

  • Baking dish/ brownie style baking tray/pan. I used a 10 x 7 inch but any similar size smaller or larger will be fine.
  • Baking/parchment paper, if necessary to easily remove concrete cake from baking pan


  • 200 grams plain flour
  • 160 grams granulated sugar or caster sugar
  • 50 grams cocoa powder
  • 100 grams plant-based margarine I use Vitalite brand
  • 1 teaspoon vanilla extract optional but recommended


  • Preheat oven to 160 Fan/180 Celsius/356 Fahrenheit/Gas 4.
  • Grease and line a baking pan with baking paper if using.
  • Melt the margarine in a saucepan or microwave.
  • If using the vanilla add to the melted margarine.
  • Add the dry ingredients to a mixing bowl.
    Pour in the margarine-vanilla mix.
  • Mix well.
  • Break up any big lumps.
    The mix should look like fine chocolate crumbs.

  • Tip the mix into your baking tin and press it all down into an even slab.
    Press quite firm so it's all compacted.
    Smooth the top.

  • Bake in the middle rack of your oven for around 20-22 minutes.
    A few minutes longer will result in a crunchier biscuit.
  • Your chocolate concrete will be soft and a little crumbly when it comes out of the oven but will firm up when cool.
    Mark into portions while soft. Either 12-15 depending on what sizes you prefer.

  • Sprinkle a little granulated sugar over the top after marking into portions.
    Leave to cool in the pan before removing.

  • Chocolate concrete cake will keep fresh for up to 5-7 days in an airtight container. Try also wrapping in foil for extra longevity.
