Sometimes you just need that chocolate fix, don’t you? Something that will satisfy the craving. You can’t beat chocolate concrete. A chocolate traybake that sets to a hard, crunchy brownie-like cake.

Many of you will remember this from your school days. It was a staple dessert back in the day before Jamie Oliver did his thing with school dinners.

While there is nothing wrong with a healthy school dinner, I might add, I think our children are missing out on chocolate concrete.

It is certainly a childhood memory for so many of us. But the good news is that you can make it yourself at home. Getting the kids involved is also a great idea.

This isn’t a cake by definition, as it does have a tougher and more crumbly texture than a standard cake, but it certainly isn’t a biscuit or brownie either. It is in a category all on its own, which is why I think chocolate concrete is special.

So if you fancy making this at home, then here is everything you need to know to make chocolate concrete.

Step-by-Step: How to make Chocolate Concrete

First of all, get the ingredients together. There are only four ingredients to make the chocolate concrete, which is incredible in itself. But having them to hand makes the process easy. Here are the four ingredients you need:

  • 200 g Plain Flour
  • 200 g Granulated Sugar
  • 100 g Dairy Free Margarine
  • 50 g Cocoa Powder (Not hot chocolate)

Makes – 9 servings, approximately (Depends on how big the pieces are you cut the chocolate concrete into)

Then you need to preheat your oven to 180°C / 350°F / Gas Mark 4.

grease your pan

Next up, line an 8″ square tin with parchment paper or grease it. This will help you get the chocolate concrete out of the tin when baked. 

flour sugar and cocoa powder

Get yourself a mixing bowl and add the flour, sugar, and cocoa powder. Give it a good mix until the dry ingredients are combined.

adding margarine

The next thing to do would be to melt the margarine. Once melted, add the margarine to the flour mix.

This is where it gets messy, and your children might want to get involved. Using your fingers, mix it all together until it resembles a crumbly mix. If you want to add any extra bits to the chocolate concrete, this is the time to do it. I have some suggestions listed below.

add to pan and press

Pour your mixture into your tin, level off, and press the mixture down to form a flat, dense cake.

Place your baking tin in the oven and then bake for 20 minutes.

bake then sprinkle more sugar

Remove from the oven and cut into 9 squares while still warm, and sprinkle with more granulated sugar.

Let cool and then enjoy all of the nostalgia, as well as the incredible taste.

Recipe Notes and tips

Chocolate concrete is likely to be a blast from the past for you. It is such a simple dish to make and one your children might like to do with you. Following the recipe is simple; however, here are a few recipe notes and tips:

  • Preparation is key with this recipe. Make sure that you have all the different ingredients on hand to make the chocolate concrete.
  • If you have children involved, make sure they are supervised when stirring or around the oven.
  • You can choose to melt the margarine in a microwave or in a pan, depending on what you prefer or have to hand.
  • If you want to make a larger chocolate crunch cake, then just double up the ingredients.

Variations you could try

Like with many recipes, sometimes you love the sound of them, but you might want to try a different variation or flavor. So here are a couple of options that you could try to transform your chocolate concrete:

  • You could add so much to your chocolate concrete cake. Anything from M&Ms, Smarties, chocolate chips, and marshmallows.
  • To keep with the texture, you could add crumbed biscuits such as chocolate cookies, Oreos, or even Biscoff biscuits, digestives, or kitkats.
  • You could try a play on the sweet and savory option, which means you could add peanuts or salted caramel chunks to the chocolate concrete cake.
  • What you serve your concrete crunch with is completely up to you. Traditionally you would get something like a strawberry pink custard, but normal custard is just as good. You could also serve it with ice cream.

Frequently Asked Questions

There will always be questions, and so hopefully, I have covered them here for you. However, if I haven’t managed to answer a question you have, then please leave a comment or get in touch so that I can help.

Can you make this ahead of time?
Yes, you can! It is one of those things that you can make ahead of time as it will last a few days stored in an airtight container. Make sure you store it a room temperature.

What should I serve with my Chocolate Concrete?
This is all down to personal preference. At school, you would likely get something like a pink strawberry custard, but normal custard is fine. You could also serve it with fruit and cream like strawberries in the summer. Another suggestion would be to warm the cake up or serve it warm from the oven with some ice cream.

How do I store any leftovers?
There may not be many leftovers, but if there are, storing them in an air-tight container at room temperature is your best bet.

Can I freeze chocolate concrete?
Yes, you can! Bake it, and then cut the concrete chocolate into pieces. Allow the chocolate concrete to cool completely before placing them on a baking sheet in the freezer. Once frozen, you can then add them to a freezer bag for easy storage. Let them defrost or pop them in the oven to warm up before eating them.
