I just had to post this because I was delighted with the way it turned out. I wanted to make a really fun birthday cake for my 3-year-old nephews, and I had the idea of creating a construction cake, with diggers, trucks and cement mixers all helping to build it – but I had a snag, because I needed to be able to transport it easily (on the train!) down to Devon where they live. So I came up with a cunning plan – I made some scrumptious chocolatey brownies, and then used them (with lashings of chocolate and sweeties) to build the cake. What that means is that this is a really impressive-looking cake that’s actually not that difficult to make (but shh, don’t tell Ozzy and Jake).
Chocolate Construction CakePrint Recipe
- For the brownies:
- 200g salted butter
- 100g margarine
- 200g dark chocolate
- 100g milk chocolate
- 5 large eggs
- 450g granulated sugar
- 1 tsp vanilla extract
- 200g plain flour
- 1 tsp salt
- To decorate:
- A selection of trucks
Preheat the oven to 180°C. Weigh out the butter and the margarine (you can use all butter, by the way, but I don’t think margarine affects the taste and it does make it cheaper) into a microwaveable bowl and add the chocolate, broken up into pieces. Microwave in 30 second blasts, stirring well in between, until you have a thick, chocolatey mixture with no lumps.
Next, whisk together the eggs, sugar and vanilla until you have a nice fluffy pale-yellow mixture, and then pour in the chocolate and whisk again until well-combined. Carefully fold in the flour and the salt.
The top should break up a bit as you cut it - don't worry, this will add to the final effect! Prepare a brownie tin by lining with greaseproof paper, and then pour in the mixture, making sure it’s evenly spread into the corners (it should be gooey enough to spread itself out fairly well). Pop in the oven and bake for an hour, until there’s a really nice crust on the top.
Allow it to cool in the tin for about half an hour, and then cut into chunky squares, and leave to cool for a bit longer. The inside should still be a bit gooey – as it cools, it will become deliciously thick and fudgy.
When it comes to building the cake, you can of course do it any way you like, but if you’re apprehensive, then you can follow my method, which I think looked pretty darn good. Arrange six or so brownies in a rectangle and pile the rest around two sides to create an uneven wall (you don’t really want it to look too tidy).
Keep one brownie back and crumble into a couple of large pieces, for rubble – put the bulldozer here, if you have one. Sprinkle with the flake, for gravel (if you have a tipper truck or something similar, this is good for the chocolate gravel) and then arrange the maltesers around the edges, for boulders.
Kitkats make good chocolate girders, but since the trucks are still preparing the ground (as it were), these should be stacked at the side. Sprinkle few crumbs around (again, this looks much better if it’s a bit untidy) and top the walls with candles, if you wish. Tip: I served this on a tray, because it’s easy to carry and none of the trucks can roll off the edge!
