Rainbow Marble Cake

November 1, 2010

It was my birthday last week so it was time for another cake. You may presume that this cake had no planning whatsoever – and you would be right! I had ordered my usual ‘Betty Crocker’s devil’s food cake mix’ that is my lazy/thrifty birthday cake staple (£1.72 for a 12 slice choccy cake!), BUT the nice man from Sainsbury’s substituted the devils food for a ‘Chocolate Swirl Cake’. Martha and Mr Peacock baked this for me in 2 loose bottom sandwich tins and Martha proved herself to be very useful eating most of the mixture before it made it to the tins. I did not hold much hope for the chocolate swirls inside the cake itself but it smelled good.

Neither Martha nor Mr Peacock were particulary confident in icing the cakes that came out of the oven so I volunteered, (even though it was my own birthday cake – I am too much of a control freak!) but Martha chose the theme, she wanted a rainbow cake with lots of colours, a quick scrootle through my baking cupboard revealed only 3 food colourings, pink, green and blue. (I do recall a recent cull of shockingly out of date food colours.) I still could not allow it to be filled with the sickly buttercream so I filled it with dark chocolate ganache. Sounds fancy but really just melted sainsbury’s basics dark chocolate mixed with whipped double cream. The buttercream is a ‘hummingbird bakery’ recipe, 500g icing sugar, 160g unsalted butter, 50ml whole milk and 1/4 tsp vanilla extract, then split into 3 and coloured. I dolloped the candy colours all over the cake and then smushed them all together as I spread the icing smoothish, adding a fancy ribbon and a sprinkling of edible glitter as an attempt to make it look a bit more glamorous but made it look a bit camp instead.

I have to say I am not sure about the result, it tasted very good and looked amazing sliced, Martha was of course delighted with it. To me it looks too much like the playdoh when all the colours get smushed up together (which my inner control freak finds particularly offensive). However I am sure there is someone who can get a much better result with a similar technique and I would love to see it.
