Birthday Cakes Delivered to London

Hand-picked by our editorial team·Updated 7 July 2026·5 products, checked in stock hourly

Finding a proper birthday cake in London that doesn't come from a supermarket shelf is trickier than it should be. We set out looking for bakers who'd ship something genuinely special to London addresses—the kind of cake that arrives fresh, tastes like someone actually made it, and doesn't require wrestling with a logistics nightmare. What emerged was a small crop of independent makers who've cracked the art of sending cakes through the post without them arriving as crumbs.

Most deliver straight across London within a day or two, which means you can order for someone's birthday without planning three weeks ahead. Some arrive in slim letterbox-friendly packaging (brilliant if the recipient's in a flat with no doorstep space), while others come as proper gift boxes you'd be proud to hand over in person. A few even let you personalise them, which turns a cake into something they'll remember.

Our 5 picks

Ranked — our favourite first.
1
A birthday cake with white icing and decorative topping

Birthday Sweetie Cake Gift

Lollylish

A straightforward, generously sized cake designed explicitly as a birthday gift—the kind that arrives looking like someone took care with it. It's the option to reach for when you want a real cake, not a gimmick, and you're sending it to someone across London who just wants proper cake and candles.

2
A box containing nine small individual cakes in assorted flavours

Little Cake Co. Birthday Box (Box of 9)

Little Cake Co.

Nine individual cakes in a single box that arrive ready to share or to give one each to everyone at the party. Little Cake Co. sends these all over London, and what makes them stand out is that you get variety rather than nine of the same flavour—useful when you've no idea what everyone will want.

3
A delicate letterbox cake decorated with pink blossom detail

Pink Blossom Letterbox Cake

bakerdays

Designed to fit through a letterbox, so if you're sending it to a Shoreditch flat or a Brixton terrace with no front garden, the recipient doesn't have to be home to receive it. The pink blossom detail means it's clearly a birthday cake, not something that's arrived by accident.

4
A letterbox cake with personalised text and decoration on top

Personalised Letterbox Cake

The Boutique Cupcake Company

Personalisation makes this one sing—you can add a name, a message, or both, which transforms it from a nice cake into something that feels handmade just for them. It still arrives letterbox-safe, so the personalisation doesn't require special delivery faffing about.

5
A birthday-themed letterbox cake with celebratory decoration

Birthday Letterbox Cake

The Boutique Cupcake Company

Explicitly a birthday cake in letterbox format, so there's no ambiguity about what's arrived or why. It's the straightforward choice when you want birthday cake to ship to someone in London and you'd rather not overthink the details.
