Celebration Rainbow Cake
Customer recipe by Rebecca McCoy
Added 66 months ago

I wanted to create a striking cake for my birthday to take into my work. It really impressed everyone and I am always getting requests for it!

Turn your oven to 160C and grease all of your sandwich tins. Mix all of your ingredients together (apart from the colours) until the mixture is free of lumps. Be careful not to overmix as this will affect how much your cakes rise.

Split your mixture between 5 small bowls and colour each a different one of your colours. Spoon into your cake tins and bake each one for roughly 15-20 minutes. Times and temperatures may vary so cook cakes accordingly and check they’re baked by inserting a skewer into the centre – if it comes out clean your cake is done!

Beat the butter and vanilla in a large bowl until soft. Add half of the icing sugar and beat until smooth.Add the remaining icing sugar and one tablespoon of the milk and beat the mixture until creamy and smooth. Beat in the milk, if necessary, to loosen the mixture. Set aside

Cool each cake. stack your cakes, adding a generous layer of butter cream between each one, starting with blue at the bottom, followed by green, yellow, orange and red on the top. use the remaining butter cream to completely cover the outside of the cake.

Decorate with as many sprinkles as you can!

Cut a slice and enjoy! For best results, do in front of an audience!

TIP! You don’t need 5 sandwich tins to make a fab rainbow cake, just cool, clean and regrease each tin after use and reuse, remembering not to open the oven door while you have cakes halfway cooked in the oven.
