Birthday Cakes for Delivery to Warwick

Hand-picked by our editorial team·Updated 8 July 2026·6 products, checked in stock hourly

We set out to find birthday cakes that actually arrive in Warwick looking as good as they taste, which ruled out most of the mass-produced supermarket options straightaway. What we discovered instead were independent bakers making cakes specifically designed to travel well through the post—no fragile tiered towers, just proper, flavourful cakes that fit through a letterbox without losing their charm.

If you're sending a birthday gift to someone in Warwick, or you live here and want something made with real care rather than a generic sheet cake, these are the ones we'd order. Most arrive within a few days, so there's still time to plan ahead. A few notes: check delivery timing if the birthday falls on a weekend, and have a proper look at the flavour and decoration details before you order—each one is genuinely different, not just the same cake in different boxes.

Our 6 picks

Ranked — our favourite first.
1
A birthday cake with decorative icing and celebratory design, packaged for letterbox delivery

Birthday Letterbox Cake

The Boutique Cupcake Company

A straightforward letterbox birthday cake that does what it says—arrives ready to celebrate, with enough character to feel handmade but practical enough not to fall apart in transit. Works for most ages and tastes.

2
A letterbox cake decorated with colourful sugared flowers and botanical designs

Birthday Flower Garden Letterbox Cake

bakerdays

The floral version for anyone who'd rather have something a bit prettier on the table. This one comes with an actual garden of sugared flowers on top, so it's less 'generic cake box' and more 'someone really thought about this'.

3
A birthday cake with 'Happy Birthday' message in icing, packaged for safe delivery

Happy Birthday Letterbox Cake

bakerdays

Clear and cheerful without being over the top. The 'Happy Birthday' message means you don't have to write your own card, and the design is clean enough to suit any age. Arrives ready to cut and serve.

4
A pastel pink decorated letterbox cake with blossom-themed design elements

Pink Blossom Letterbox Cake

bakerdays

Soft blush tones and delicate decoration make this one particularly popular for milestone birthdays and anyone who prefers elegance to joviality. The pink colouring runs through the cake itself, not just the frosting.

5
A letterbox cake with a diamond pattern design and space for customisable age number

Any Age Diamond Letterbox Cake

bakerdays

Need to put an actual age on the cake? This one works because you can specify the number you want—no awkward blank space, no guessing. The diamond pattern gives it a slightly grown-up feel, good for the sort of birthday people actually want to acknowledge.

6
A birthday cake gift box containing both cake and assorted sweets and treats

Birthday Sweetie Cake Gift

Lollylish

If the person loves sweets as much as cake, this hybrid gift box combines both. It arrives as a proper cake but shares space with confectionery, so it reads less like 'just a cake' and more like a proper birthday package.
