Letterbox gifts, through your door.

Choose the box
The postal boxes are packed flat in a single layer and go through the door like a large letter. What goes inside is up to you. The vegan cakes are a local order for now, because those postal recipes are still being worked out.

What goes in a letterbox box
Three kinds of bake, all chosen because they travel beautifully. Fudgy hand-cut brownies in six varieties, from plain through triple chocolate to caramel and sea salt, thick-cut slices of lemon loaf and banana bread, and cookies in five kinds with two to a box. The baker's choice treats box mixes all three. Everything is all-natural, made with real butter and real chocolate, from the generational recipes passed through the years.
The bakes are packed flat in a single layer, so nothing gets squashed and everything arrives looking the way it left. Each box carries a full ingredient and allergen label, the same as every Sploffin order.

The short version
How letterbox delivery works
Baked when you order
Letterbox boxes follow the same rule as everything else here: I bake when you order, in one small batch, and your box goes straight into the post, never into a warehouse. Brownies and loaf cakes are dense enough to be at their best for days, which is exactly why they're the bakes I post.
A box built for the letterbox
The box is designed around the standard UK letterbox slot, with the bakes sitting flat inside it. It's designed to post like a large letter, so nobody should need to be in to sign for anything.
Anywhere in the UK
Collection and delivery stay local to Peterborough, but letterbox boxes travel by post, so this is how my baking reaches the people who live further away.
Cake through the post, for the days that need it
A birthday you can't be at, a friend having the kind of week that calls for chocolate, a thank-you an email doesn't quite cover. A box of good cake says it better than a card on its own, and it fits through the door while they're at work.
The waiting list
Be first through the letterbox.
The letterbox boxes are on sale, and the list is still worth joining if you are waiting on a box that is not ready yet: one email the moment it opens, nothing else.
Wondering how a bake survives the post? The blog has the long answer on letterbox brownies by post, a guide to letterbox cakes by post, and one on letterbox Christmas gifts. Choosing for a thank you, a get well soon or a new baby? My letterbox gift ideas go occasion by occasion.
Letterbox questions, answered
What is a letterbox brownie box?
A letterbox box is a slim box of fresh bakes, designed to slide through a standard UK letterbox, so it arrives with the post and nobody has to wait in for a courier. Sploffin's boxes hold hand-cut brownies and thick slices of cake, baked to order in my Peterborough kitchen and posted anywhere in the UK.
What kinds of letterbox gift are there?
Five postal boxes, all on sale now: sliced lemon loaf cake, banana bread with walnut, letterbox brownies (six kinds including blondies), letterbox cookies (five kinds, two to a box), and the baker's choice treats box that mixes them. There is one more page for the vegan cakes: vanilla, chocolate and carrot, made to order locally while the postal versions are still being worked out.
Will it fit through my letterbox?
The boxes are designed around the standard UK letterbox slot: the bakes are packed flat in a single layer, and the box is designed to post like a large letter.
How fresh do the bakes arrive?
Brownies and loaf cakes are the right bakes for the post: dense, moist and at their best for days, unlike delicate pastry. Every box is baked for your order, never pulled off a shelf, and each one carries a full ingredient and allergen label with a best-before date, so you can see exactly what you're eating and when to eat it by. They are at their best within five days of arriving.
Can I send a letterbox box as a gift?
Yes. Letterbox boxes are made for gifting: add a message with your order and I'll include it in the box. I don't put invoices in gift boxes.
Where do you deliver letterbox boxes?
Anywhere in the UK with a letterbox. Collection and delivery stay local to Peterborough, but letterbox boxes travel by post, so this is the way to get Sploffin bakes if you live further afield.
Can I get a letterbox gift delivered next day, or the same day?
Next day, yes, on a day you book: choose DPD next day at checkout and any Tuesday to Friday at least three days ahead, and DPD's next-day service carries it for that day, on the UK mainland. Same day, no, because every box is baked to order for the day it travels.
Can I send letterbox gifts to several people, or order for a company?
Yes. The checkout takes one address per order, so for a few people place an order each, each with its own handwritten card. For a longer list or a company thank you, email me the addresses and what you would like in each, and I will price the whole run at once. For staff birthdays, the Birthday Book books the whole year in one payment.
When can I order a letterbox box?
Right now. The lemon loaf cake, banana bread, brownies, cookies and treats boxes are all ordered and paid online and posted anywhere in the UK, with Royal Mail postage added at checkout. The vegan boxes are the one part still being worked out for the post.
Letterbox bakes from a very small kitchen
Sploffin letterbox delivery is fresh brownies by post, alongside thick-cut cake slices, baked to order in a registered home kitchen in Peterborough and sent anywhere in the UK in a slim box designed for a standard letterbox. Everything is all-natural: real butter, real chocolate, real vanilla, and a full PPDS allergen label in every box.
Sploffin letterbox brownies and cake slices are baked by me in small batches, in the same kitchen as the pastries and pies, using generational recipes, not a commercial production line. If you're after a celebration cake instead, that's the personalised cakes side of the kitchen.
