Chocolate cake and children / spiced rum cake

With chocolate syrup, honeycomb ice cream, chocolate tuile and cocoa nibs

This began because Fabian and Etien kept nagging me to serve my honeycomb ice cream on its own as a dessert. Flattered as I was, a simple three scoop bowl is not a fitting finish to a New River Dining evening. But I did want to highlight the ice cream rather than just serve it on the side. It is one of the best things I've ever made. An obvious choice would be a little chocolate sponge underneath. A good contrast of texture, colour and flavour but not so rich (well...) that it detracted from the star.

I have a long history with chocolate cake; Guinness cake to be exact. It was for many years my children's favourite (Belinda was quite partial too). There were several birthday cakes where Guinness was the foundation. The most memorable and successful was probably the penguin at Etien's (count 'em) ninth birthday.

Fabian and I use to sell cakes to friends and neighbours to fund raise for his Scouting trips too. The best loved was our Chocolate rum sponge, based on devil's food cake. Sadly this was in the days before smartphones, so no picture.

For the honeycomb partner I decided on a spiced rum cake based on a devil's food recipe. These can be either light and airy like a traditional chocolate sponge or dense and fudgy like a brownie, well almost, but much more tender. Mine is somewhere in the middle. Using almost a half bottle of rum bumps up the cost of course and I should point out that not all the alcohol is removed by the boiling and baking.

But I didn't want a dry cake underneath so I made, for the first time, a chocolate syrup to pour over. The ice-cream looks great melting into this but it also helps with the transit from kitchen to guest. 

You can make several variations using this recipe. Omit the rum and/or the allspice for a more traditional flavour, especially for a children's party cake - unless you want a really successful, but legally problematic, bout of post prandial sleeping lions.

This was a test bake, quite a fudgy one.

Makes one twin layer cake or at least a dozen small ones as pictured.

In a bowl add 250ml boiling water or a water/dark rum mix of your choice to 50g Valrhona cocoa powder and 120g dark muscovado sugar. Mix thoroughly until a smooth, thin paste. Allow to cool.

In another bowl, cream together 125g soft unsalted butter with 120g caster sugar. When pale and fluffy, mix in two large eggs, then fold in 250g plain flour with a half teaspoon each of baking powder and bicarbonate of soda and a good pinch of allspice powder.

Now add the cooled chocolate/rum mix, along with two teaspoons of vanilla extract or paste. 

For a large cake, line the bottoms of two round 20cm/8" cake tins with baking paper and butter the sides. For the small, I use something similar to a muffin tin. This should be well buttered.

Bake the large cakes for around 30 mins mins in a 180°C oven, until a wooden sewer comes out clean and the cake is just starting to come away at the sides. The small cakes only need about 18 mins for fudgy or 21 mins for spongy.

Makes about 400ml. That's a guess. I didn't check and I kept tasting so maybe 400ml and several spoonfuls?

The quality of the cocoa powder and chocolate is fundamental to this. I always use Valrhona (sadly they don't sponsor me). Green and Blacks is the next best and more available. I say 'next best', but it's not nearly as good. This is a wonderful, dark, glossy pouring sauce. It will coat the top of your cake and slowly dribble over the edges in thick, sexy rivulets. (Yes, sexy. Hey, I'm 50 this year, give me a break.)

Gently heat 100ml of water with 200g of caster sugar. When dissolved, add 50g of cocoa powder to make a chocolate syrup. Allow to cool.

In another small pan, gently heat 100ml of double cream until just bubbling. Stir in 150g of 70% dark chocolate broken into small pieces to melt in the warm cream. Stir until smooth.

When the syrup is cool, mix in the chocolate cream mix. Blend until glossy and thick.
