The only chocolate cake recipe you will ever need. I’ve made this cake in various forms - bundt, four-layered, traybake style - and every time I share a slice with family and friends, there is a mention of it resembling that cake that was devoured by greedy little Bruce Bogtrotter from Roald Dahl’s Matilda. Deliciously dark and decadent, this is the ultimate, can’t wait to get in your mouth chocolate cake, that I’m sure that the fierce and tyrannical Miss Trunchbull would be delighted with.
2tbspinstant coffee (mixed in with 100ml of water)or a single shot of espresso
85gself-raising flour
85gplain flour
1/4tspbicarbonate of soda
200gdark muscovado sugar
200ggolden caster sugar
30gcocoa powder
3eggs
75mlbuttermilk
For the chocolate ganache
300gdark chocolate
500mldouble cream
Instructions
Preheat the oven to 180C. Butter your cake tins. (Quantities work well for two tall 6-inch tins or two regular 8-inch tins.)
Melt the chocolate and butter in a pan over a low heat.
Mix 1 tbsp instant coffee granules into 100ml cold water and pour into the pan or add your single shot of espresso
Mix all the dry ingredients; flour, bicarb, cocoa, sugars etc.
Whisk the eggs and buttermilk together.
Combine the wet and dry ingredients and then pour into your cake tin(s).
Bake at 180C for 25 minutes or when a skewer poked in comes out clean. Cool on wire rack in tin(s).
For the chocolate ganache
Heat the double cream and chocolate in a pan. The mixture must start to boil but be careful not to let it burn.
To decorate
Wait till cooled and spread between and on top of the cake (if doing two or just on top of one).
The ganache can also be used to make truffles to decorate. Simply refrigerate/freeze until the mixture is a little more solid. Then roll into balls with your hands and then roll into cocoa powder or nuts to allow the truffle to keep its round shape.
This cake is great with just the ganache but feel free to add any kind of decoration on top - edible flowers, meringues, truffles etc.
Notes
If you don't have buttermilk then you can substitute for normal milk or even plant-based milk. I have made with all three and had great results.
If making this in the summer and you're worried about the ganache melting, then just add more dark chocolate to your ganache to firm it up.
