Mocha Fudge Cake with Coffee Icing
I made and decorated this as a birthday cake, although it’s probably best described as a ‘cafe cake’. It seems we have developed something of a family tradition over the last few years, namely that the birthday person chooses a cake from the cake book and I make it for them. This time around it was the lass’ turn and, given that she was turning 4, she obviously wanted the BIGGEST chocolatey-ist cake available … turns out that this isn’t it!
I should’ve paid attention when she was choosing, this ones a bit more involved than I would generally bother with and used multiple (2) cake tins in a size (20cm) that I only had one of … ho-hum, such is life though!
What this cake is, is the BIGGEST coffee-ist cake that there is. It’s big, it’s rich, it serves 10, and … it’s too much for us! If you’re not a fan of coffee then I would suggest substituting the coffee in the icing for cocoa, or simply reducing the amount of coffee in the icing by about half.
What you’ll be needing:
The Icing
- 175g plain chocolate + extra (for grating)
- 50g unsalted butter
- 150ml double espresso or cocoa
- 1tsp vanilla extract / flavouring
- 300g icing sugar + extra
For the Sponge
- 300g plain flour
- 2tsp baking powder
- 2tsp vanilla extract / flavouring
- 3 eggs, seperated
- 3 tbsp coffee granules
- 85g unsalted butter
- 280g caster sugar
- 85g plain chocolate + extra (for eating … yum!)
- 125ml soured cream
- 125ml milk
What you’ll be doing:
- Chuck all your icing ingredients in a pan and heat gently whilst stirring until all the chocolate and butter is melted and everything is combined. Do not boil, do not burn.
- Take all your icing ingredients and chill for a few hours - I left mine in the fridge overnight.
- Heat your oven to about 160C or 150C if it’s a fan oven.
- Line and butter two 20cm cake tins – or if you’re like me, panic momentarily because you didn’t read the recipe first and then decide that you’ll just have to cook the sponge in two batches!
- Gently heat half your milk, or thereabouts, until warm but not boiling. Then add your coffee granules. Mix back in with the rest of the milk and leave aside to cool.
- Sift the flour and baking powder into a bowl and place aside.
- Mix the 1tsp vanilla into the egg yolks and 1tsp vanilla into the egg whites – it’s easier this way, it means you don’t need to worry about getting mixed up and accidentally adding it to the wrong one - put these aside for the moment too.
- Cream the butter and 200g of the sugar together – just chuck it in your food processor - add the egg yolks and mix these in too before transferring to a bowl.
- Melt your chocolate and mix this in too.
- Fold in your sifted ingredients, the cooled coffee-milk and the soured cream. Place the bowl aside – and curse the flour that’s spilt all over the place!?
- Whisk your egg whites until stiff – curse the too small bowl you put them in earlier and transfer to a larger bowl, whisk again.
- Whisk in the remaining 80g of sugar until it forms stiff peaks – stick your finger in and revel in it’s meringuey goodness.
- Fold the egg whites into the sponge mixture and divide between your tins – or put half of it in your only tin and bake in two batches. Bake the sponge for about 25 minutes before checking with a skewer or knife (stab it into your cake, it should come out clean), return to the oven for another five minutes if it’s not ready.
- Cool each sponge on a wire rack.
- Check your chilled icing mix, hopefully it should be a workable consistency, if it’s not add more icing sugar – mixing vigourously - until it’s thick enough to set on the cake.
- Split each sponge in two and layer with the icing, ice the cake outers too.
- Grate some of the extra chocolate and sprinkle over - this might have been nice through the layers too.
- Decorate as you see fit.
- Consume.
Of course, birthday’s aren’t just about cake, there’s also fun and laughter and generally enjoying each others company. With that in mind we headed out to Mabie Farm Park in the blazing sun and had a whale-of-a-time.
