Vanilla buttercream also covers the entire cake and it is then coated very generously in a cloud of white chocolate flakes. The perfect rainbow birthday cake for any age, or a great cake to cheer up a loved one.

How do I look?

Our Rainbow Cake is perfect for birthdays, christenings, baby showers or even just to cheer someone up! Filled with four vibrant layers of fluffy vanilla sponge and held together with deliciously sweet vanilla buttercream. It is then coated in more vanilla buttercream and covered with a cloud of white chocolate shavings. Comes with a pretty rainbow topper to decorate (not edible). STORAGE - Please store me in an air-tight container in a cosy spot - I don't like being kept in the fridge. Can be frozen for up to 6 months.

How do I arrive?

Our sponge cakes are packaged in secure and robust packaging. The inner box is wrapped around the cake to securely hold it in place so the sides and top do not get damaged in transit. The box also includes a handy cutting guide! It is then put in a strong cardboard outer box for extra protection so it will arrive to you safely.

    The Rainbow Cake is absolutely delicious. Lovely and moist and not too much icing with all the layers to make it overly sweet. Hopefully this will be a permanent addition to the Sponge family. I would love to see a chocolate layered cake with a ganache filling with the normal chocolate icing.

    We got the rainbow cake for a birthday and the NHS anniversary! It went down very well with friends and neighbours. Just the right size (a bit bigger would have been even better)!
