Everything You Need to Know About Letterbox Cakes

What Is a Letterbox Cake?

A letterbox cake is a freshly baked cake packaged specifically to fit through a standard UK letterbox.

 

Unlike traditional cake delivery, which often requires someone to be home, a letterbox cake is:

  • Slim enough to post
  • Securely packaged for transit
  • Protected to prevent damage
  • Designed to stay fresh during delivery

Letterbox cakes are becoming increasingly popular in the UK because they combine the joy of cake with the convenience of postal delivery. They’re smaller than traditional celebration cakes but just as thoughtful - and far easier to send.

 

At MailBakes, our letterbox cakes include two slices of handmade cake inside beautifully designed packaging, combining cake and gifting in one convenient delivery.

 

If you’re looking for a format that blends cake, convenience and creativity, letterbox cake delivery is the modern solution.

Why Choose Letterbox Cake Delivery? 

Traditional cake delivery can be:

  • Expensive
  • Bulky
  • Inconvenient
  • Dependent on someone being home
