    Amazing cake!! So tasty and even though not the biggest cake with all the layers you couldn’t eat too much. Over all really happy and will be ordering another cake very soon

    My only flipside comment would be that I was expecting the sponge layers to have similar rainbow colours to the website picture; it was multicolour but didn't say rainbow to me. This didn't detract from the eating experience!

    A little too dry for our liking for a sponge. Topper did not come with cake and so let the final presentation down a little.

    This cake not only looked spectacular but the taste well and truly lived up to expectations. Moist and beautifully balanced, not too sweet or sickly. The white chocolate was lovely and it was the perfect size. The colours inside were vibrant and I will definitely order again!!

    Have used Sponge.co.uk on lots of occasions from the cake cards to small sponge cakes to larger cakes. All have been excellent. I have added cards plus tea bags to pop to prosecco and also added various candles. All brilliant and well presented. Wouldnt hesitate to recommend. All cakes are delicious !!! Will keep on using as brilliant for surprises and cakes always go down well. !!!!

    Everybody commented on how tasty it was - it was one of the best tasting birthday cakes I’ve ever eaten - I would by again even without an occasion! It was a decent size - got around 10-12 helpings out of it - and it looked identical to pictures. Honestly cannot recommend this enough!!

    The cake was ordered for my adult step-daughter’s birthday. She and her family said it both looked and tasted delicious. However, the rainbow decoration was broken when the cake was unpacked.

    I was happy that it looked like the picture on the website. My daughter and family were very pleased with it both for looks and taste. I was happy that my daughter had a cake to celebrate her 40th birthday. I will be able to taste it once we are able to meet as they have frozen a slice for me.
