Birthday cakes to order and deliver to Tenby

Hand-picked by our editorial team·Updated 9 July 2026·6 products, checked in stock hourly

Finding the right birthday cake in Tenby used to mean a trip into town or hoping the local bakery had something in stock. These days, you can order something genuinely special from independent makers across the UK and have it delivered right to a Tenby address—often within days. We've tracked down cakes that travel well, arrive fresh, and actually taste like they were made by someone who cares, not churned out by a factory.

What matters when you're ordering a cake for delivery is knowing it'll arrive in one piece and taste as good as it looks. The letterbox cakes here are designed to do exactly that: they're baked to fit through the post, packaged to survive the journey, and flavoured so well you'll wonder why anyone bothers with a supermarket sponge. Whether you're marking someone's milestone or just want to surprise a friend without the fuss of collecting something in person, these are the ones worth ordering.

Our 6 picks

Ranked — our favourite first.
1
Letterbox cake decorated with 'Happy Birthday' message and festive icing details

Happy Birthday Letterbox Cake

bakerdays

This is the straightforward choice if you want something unmistakably celebratory without overthinking it. The baker has got the balance right between enough decoration to feel special and enough structural sense to arrive in Tenby intact. It's the cake you'd feel confident sending to someone you want to impress.

2
Letterbox cake with diamond pattern decoration in neutral tones

Any Age Diamond Letterbox Cake

bakerdays

If you're buying for someone whose age you'd rather not announce on the cake itself, this one solves that problem elegantly. The diamond design is sophisticated enough that it works whether you're celebrating 30, 50, or somewhere in between—and it means you're not committing a number to frosting.

3
Letterbox cake with delicate pink floral decoration and blossoms

Pink Blossom Letterbox Cake

bakerdays

We found this one works beautifully for anyone who'd rather receive something pretty than something heavy on the sugar. The pink blossom detail means it looks like the baker spent time thinking about who it was for, but it arrives small enough to fit through any Tenby letterbox without ceremony.

4
Letterbox cake decorated with a colourful flower garden design

Birthday Flower Garden Letterbox Cake

bakerdays

This is the one to choose if the person opening it loves flowers as much as they love cake. The garden design is cheerful without being childish, and it means the cake itself becomes part of the birthday present rather than just the refreshment afterwards.

5
Letterbox cake with simple, understated birthday decoration

Birthday Letterbox Cake

The Boutique Cupcake Company

Sometimes you want something that doesn't need to do anything fancy—just cake, done well, that arrives ready to eat. This one strips away the decoration and lets the baking speak. For Tenby delivery, it's reliable and straightforward, arriving fresh and tasting homemade.

6
Birthday cake gift box with sweets and treats alongside the cake

Birthday Sweetie Cake Gift

Lollylish

The sweetie cake gift is the one for people who want more than just cake in the box. Opening it feels like an actual present rather than a delivery, and if you're sending it to Tenby for someone you don't see often, that matters. The sweets bundled with it mean there's something to share.
