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.
GET THAT SWEET SPOT
Buttercream loves a gentle warm-up, and brownies need a little patience to reach their soft, gooey magic. Our bakes have been chilling in transit and need time to be their best so if your sponge is a little dry give it some more time.
ROOM TEMP, BEST TEMP
Let your bake rest in their packaging for up to 12 hours or when it reaches room temperature. It will then be at its full, fluffy glory. Cake is always at its best when it’s cosy, not chilly.
KEEP IT FRESH
Pop leftovers in an airtight container and store somewhere cool and dry... no fridge chills or sunbathing, please! Keeping them at room temperature keeps your bakes soft, gooey, and full of joy.
FREEZE FOR FUTURE JOY
Celebration postponed? Wrap your cake carefully and freeze for up to six months. When you’re ready, thaw at room temperature to bring back that soft, fresh-baked magic you love.

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.
