    Rainbow Cake

    It’s a colourful dream come true! Paint your palette with pure perfection in the form of a four-layered, fantastically flavoursome vanilla rainbow cake.

    This product is no longer available. Why not try one of our alternative products?

    Layers upon layers of vibrant sponge are slathered with clouds of fluffy buttercream and scrummy white chocolate shavings. Don’t worry; your unsuspecting, vibrant-loving friend won’t suspect a thing; they’ll go about their party thinking you’ve got them a delicious yet seemingly BORING coloured cake (no offence to all our monochrome cakes, we still love you). They’ll be over the rainbow when they cut into this beauty and a spectrum of bright hues shine out! Along with a rainbow topper for decoration, this cake will leave your special someone feeling like they’ve stumbled across a pot of gold with a friend like you!

    And fear not, whether you're nestled in Norfolk or lounging in Lands End, we've got your delivery covered with our express pigeon post. Just kidding – our couriers might not have wings, but they sure get to you quickly.

    • Brilliant cake for our son’s first birthday, super simple on the outside (which we wanted so we could add our own decorations) but with a surprise rainbow filling which our 2 year old niece and nephew loved! Cake is very sweet but tasty and everyone loved it. Delivery was super quick too the cake arrived in perfect condition. We needed it to be delivered during that awkward period between Christmas and new year and Sponge was one of the few places that could provide that - free of charge as well. First time ordering but cannot fault them, have already recommended to family.

    • It tasted as good as it looked but I would have preferred it without the chocolate shards and just the fantastic buttercream

    • This was a truly stunning cake! There were 4 layers - red, blue, yellow and green - all with a beautiful vanilla buttercream between each layer and topped off with vanilla buttercream and white chocolate that tasted just like Milkybars! My partner loved it as did my Mum! We're looking forward to next year for another instalment.

    Did you know?

    Our Rainbow Cake is a multi-colour vanilla layer cake with deliciously sweet buttercream sandwiched between layers. It is also covered with a generous layer of vanilla buttercream and white chocolate flakes. If you're looking for a delicious rainbow cake to buy online‚ order one from Sponge!

    These will make an excellent statement piece for any celebration and are particularly fun for birthdays. The generous size of the cake, with its multiple layers and thick buttercream and coating, means that the cake will easily serve more than 8! There are plenty of personalisation items to add to create an amazing party package too including cards, candles, balloons, drinks and more!

    It's so easy to order our Rainbow cake online - just pop it in your basket, go to the checkout, pop in the delivery details, choose your rainbow cake delivery date and make your payment. Simple!

    You can get one of our yummy Rainbow Birthday Cakes delivered anywhere in the UK! We deliver all over the country, including; London, Birmingham, Norwich, Manchester, Newcastle, Glasgow, Liverpool, Nottingham and Northern Ireland! You can even send one to a friend, loved one or family member; we deliver them straight to the door.

    We know most of our cakes don't make it there but it's good to know you can freeze your Rainbow Sponge for up to 6 months! Either pop it in the freezer whole in its packaging (if you're saving it for a special occasion) or cut it into slices and put it in airtight containers. When you're ready for it, take it out of the freezer and leave it in a nice cosy spot for 24 hours to get it up to room temperature. Then you'll be able to enjoy your scrumptious cake.

    STORAGE - Please store me in an air-tight container in a cosy spot - I don't like being kept in the fridge.
