Chocolate Lego

It was sometime last year that I first came up with the idea of combining two of my favourite things – choclate and Lego – but didn’t really know where to start. I knew I’d need some kind of mold, but never got around to working out the best way to make one.

Chocolate LegoAnd then I discovered Lego Ice Cube Trays and immediately knew they’d be perfect for what I wanted. Unfortunately, the Lego shop doesn’t sell the trays in the UK, but a quick search of eBay and I found one.

My plan was simple. Instead of filling them with water, I’d just use melted chocolate. And – much to my amazement and delight – it actually worked.

My Chocolate Lego did contain a few imperfections, but I think that just adds to the character.

The process was very simple:

Chocolate Lego1. Melt the chocolate. The best way to melt chocolate is in a bowl over a saucepan of boiling water. That way you can control the temperature so the chocolate melts evenly and won’t burn. You can use any chocolate for making your bricks, but I found dark chocolate works best simply because it’s harder than milk or white chocolate.

2. Spoon or pour the chocolate into the mold.

Chocolate Lego3. Use a plastic spatula to smooth the chocolate into the mold, making sure to push it into the corners. Make sure the chocolate is exactly level with the top of the mold to give the bricks a nice flat, even base.

4. Put it into the fridge to set. I recommend leaving it overnight to make sure the chocolate is solid all the way through. This will make it much easier to remove from the mold.

5. Once set, simply push your chocolate lego out of the tray. I found the bricks came out very easily as the tray is made of soft rubber. If you need to, use a sharp knife to trim off any excess chocolate from the bricks.

Building With Chocolate Lego

You may have noticed the obvious drawback of making chocolate Lego in this way. Because the bricks are solid, you can’t ‘click’ it together like real Lego. But this is chocolate, and even if you could click it together, you’d probably never get it apart anyway!

The best way to build with these bricks is simply to treat them like proper bricks – i.e. use a cement to stick them together. By ‘cement’, I do of course mean icing/frosting. Pretty much any icing will do, but why not try Simon’s recipe for chocolate fudge icing.

Taking it Further

Making Chocolate Lego this way is incredibly easy, and once you have a supply of bricks, there’s no end to what you can create. You could use different combinations of dark, milk and white chocolate – or even add a few drops of food colouring to white chocolate to make coloured bricks.

So why not get building and let us know what you come up with. There may even be a special prize if anyone manages to create a Chocolate Lego Dalek Cake

  1. How clever! I know Ikea sells lots of those rubbery ice cube mold thingies that I should now go buy with a new purpose in mind.

    Oh my god!

    It’s an under-11’s dream!

  3. Nice, but can you build stuff like this with it…

  4. Well done Dom – ain’t it great what an intelligent mind can do when it’s in need of chocolate? I showed this to my eight year old who was in awe, responding with “Cool AS!” so you should now take this to Lego and Cadbury’s and see what kind of dream product can be made with it

    If you had two molds you could put the second one at the top making round holes at the bottom of the bricks as they set.

  6. Before you fill the chocolate into the form, make several layers of chocolate with a brush. Prevents bubbles.

    Ah – a world of potential opens up 🙂 How about gelatin buildings – lit up from the inside?! “stained glass” legos….

    If you a more authentic brick, use real lego bricks to stamp the indentation into the bottom of the chocolate brick before cooling-they may then be stackable.

    The alternative is to make like easter eggs and fill the mould and then tip upside down leaving just shell.

    Yeah, I’d certainly considered using real lego bricks to make indentations on the bottom. I’m sure if you want real accuracy, you could actually make your own molds from real lego bricks too.

  10. Oh wow, that’s so cool! What a great idea! You could do a chocolate house for Christmas instead of Gingerbread using gumdrops for people heads. Coo.

  11. This is brilliant! My boys are going to love it 🙂

  12. Great stuff. I’m adding a link to my Squiddoo page on chocolate. This will be very popular!
