Our Guarantee

We’re so confident in our cakes that we offer a Better-Than-Risk-Free Guarantee: if it doesn’t delight you, hand it back to the driver for a full refund — no questions asked.

Decorations: Decorated in a cute comic cake style, entirely with buttercream, this cake slice features graphic-style outlines — complete with a cherry on top! It's designed to look like a giant slice of rainbow cake but it’s covered completely with buttercream, making it a fun, Instagram-worthy centrepiece.

Cake Sponges: Five layers of freshly baked vanilla sponge in bright rainbow colours, made by hand using our artisan recipes for a light, fluffy texture. Each layer is filled with our signature vanilla Swiss meringue buttercream for a smooth, balanced flavour.

Frosting: Our silky vanilla Swiss meringue buttercream — naturally less sweet than standard icing — is whipped to perfection for a creamy, cloud-like finish.

There’s something irresistibly cheeky about a giant slice of cake pretending to be… a slice of cake. We designed this as a bespoke celebration cake that mixes humour, craftsmanship, and flavour. Beneath the playful design lies five layers of soft rainbow sponge, sandwiched with smooth vanilla buttercream, each bite delivering pure joy.

This cake isn’t just for birthdays — it’s perfect for milestone celebrations, office parties, or anyone who wants a cake as unique as their event. It’s big, bold, and unapologetically fun, yet still carries the hallmarks of an artisan creation — hand-piped details, perfectly baked sponge, and premium ingredients.

Whether you’re ordering for yourself or surprising someone else, our Comic Rainbow Birthday Slice Cake turns any table into a show-stopping display. Freshly baked to order and delivered straight to your door with complimentary delivery.

Allergens: 🌾 Wheat (gluten), 🥚 Eggs, 🥛 Milk (dairy), 🌱 Soya, 🥜 Nuts and Peanuts. All our cakes are handmade in a kitchen that handles these allergens every day.

For this reason, we cannot in good faith label any cake as truly “free-from” or vegan — achieving that level of separation would require entirely separate premises. If you have a severe allergy, we recommend speaking to us before ordering so we can advise you personally.
