If you have walked past a dessert shop in Manchester in the last few years you have seen one: a tall, dark, glossy slab of chocolate cake, sold by the slice, usually warmed. The menu calls it a Matilda. Nobody ever explains why.
Where the name comes from
It is a Roald Dahl reference. In Matilda there is a scene where a boy called Bruce Bogtrotter is made to eat an enormous chocolate cake in front of the whole school as a punishment, and he simply keeps going and finishes it. The 1996 film made the cake iconic: black, wet-looking, almost obscenely rich.
That is the cake dessert shops are referencing. The name is not a technical term and there is no fixed recipe behind it. It is a promise about a particular kind of excess.
What it should actually be
The version that has settled into British dessert menus is fairly consistent, and it has three parts.
Layers of chocolate sponge. Usually four, sometimes more. Thin layers, not two fat ones. The layering is what gives you the ratio of cake to filling in every forkful.
Ganache between and over. Not buttercream, not whipped frosting. Ganache is chocolate melted into hot cream, and it sets dense and glossy rather than light and sugary. It is the difference between a birthday cake and a Matilda.
Served warm. Heat softens the ganache and brings the cocoa forward. A cold slice straight from the fridge tastes flat and waxy by comparison.
How to spot a bad one
Frosting instead of ganache. Look at the cut face. Ganache is dark, dense and slightly shiny. Buttercream is matte, paler and holds air bubbles. If it looks like a supermarket birthday cake, it will taste like one.
Dry sponge. A Matilda should be damp. The sponge is usually soaked or made with oil rather than butter for exactly this reason. If it crumbs dry when you press it, it has been sitting cut for too long.
Too few layers. Two thick slabs with a smear in the middle is a chocolate cake. It is not this.
Sweetness with no bitterness. Good ganache carries some cocoa bitterness underneath the sugar. Without it the whole slice is one-note and you will not finish it.
The variations
Most places now run several. The common ones:
Kinder. Milk chocolate and hazelnut, usually with Bueno pieces on top. Sweeter and softer than the original.
Kunafa. The Middle Eastern pastry, shredded filo toasted in butter, layered onto or into the cake. It adds a crunch and a slight saltiness that cuts the sugar, and it is the variation most likely to win over someone who finds chocolate cake boring.
Strawberry and Nutella. Fresh fruit against the ganache. The acidity does a lot of work.
White chocolate. A different animal. No cocoa solids means no bitterness, so it lives or dies on what is done alongside it, usually coconut or a fruit.
Why it is a late-night dessert
Cake sold by the slice suits late trading in a way that plated desserts do not. It holds, it travels, it does not need assembling to order, and warming a slice takes a minute rather than ten. That is why the dessert shops that stay open past midnight in Manchester almost all sell some version of it.
The flip side is that a slab cut at six in the evening and sat under lights until one in the morning will be dry. Somewhere cutting from a whole cake to order will always give you a better slice.
Where to get one in Manchester
We serve Matilda cakes at Lahori Lane on Redgate Lane in M12, until 2:00am, seven nights a week. Four layers of chocolate sponge stacked with glossy chocolate ganache. The Original is eight pounds, and the Kinder, Kunafa and Strawberry and Nutella versions are nine. There is also a White Matilda, four layers of soft sponge with white chocolate curls and a coconut finish. The full dessert menu is here with prices.
It is a drive-in, so nothing is eaten standing in a queue. Park where the attendant points you, put your hazard lights on and it comes out to the car, boxed if you are taking it home. Longsight, Gorton, Ardwick, Levenshulme, Openshaw and the city centre are all a short drive from Redgate Lane.
The short version
Named after the Bruce Bogtrotter scene in Matilda. Four thin layers, ganache rather than buttercream, damp sponge, served warm, with enough cocoa bitterness underneath to stop it cloying. If it looks matte and pale on the cut face, order something else.
