The making of the epic rainbow cake. For this cake you will need to dust off your calculator and brush up on your math skills! Before you get carried away and start mixing, you must weigh the bowl that you will be making the batter in.
To start, grease and line as many 9” sandwich tins as you can get your mitts on. I line my tins with foil instead of baking paper as it sits flatter against the tin. I made up a double quantity of red velvet cake batter, however this had to be white cake so I didn’t put any cocoa in, and instead replaced this with 3tsp of vanilla extract, and I did not dye the batter red. I used this red velvet cake recipe http://www.goodtoknow.co.uk/recipes/475341/Red-velvet-cupcakes.
Now the math begins. Weigh the entire bowl of cake mix. Subtract the weight of the mixing bowl. Divide the remaining number by 6. Take a smaller bowl, pop it on the scale and press the tare/zero button to set it to zero. Weigh 1/6th of the batter into that bowl. Mix in one of the rainbow colours, I started with red and worked my way through the colours in the poem order (Richard Of York Gave Battle In Vein) so I didn’t mess up and miss any out. It is important to use a gel / concentrated food dye if you want a super funky bright rainbow.
Repeat the above step for all of the cake mix and bake in batches of however many tins you have for 15 minutes, or until it springs back when you poke it. I had 3 tins but only two would fit in the oven at once.
Leave to cool - this is super quick because the cakes are so thin.
Mix up a double batch of cream cheese frosting - 100g unsalted butter, 250g full fat cream cheese, 600g icing sugar. Fill and crumb coat the cake.
You now have a choice, you can either mix up a batch of frosting of your choice to smooth on / pipe frosting roses on etc. or roll out a nice thick layer of sugar paste and smooth over the cake. This can be left plain white or decorated in any which way you please. I painted mine with food dye because I had never done this before and wanted to for so long!
I hope you have a go at making this cake, it is actually amazing and is literally the epiphany of joy. Spread a little happiness :)
