Cookies delivered UK-wide should be the easiest present there is: a box of proper cookies, baked for the day, waiting on somebody's doormat with a note inside. Mine are £18 for a box of six, baked to order in my registered home kitchen in Peterborough. The six slip through the letterbox by Royal Mail 1st Class, anywhere in the UK, so nobody has to be in. Any of my cookie boxes can go by DPD's next-day courier instead, on a day you choose, to mainland UK. This guide covers the questions I am asked most about having cookies delivered in the UK: the letterbox, the real story of next day delivery, how long cookies keep, the full cost with postage, and sending a box as a gift with no price tag inside.
I bake alone, in small batches, using generational recipes from my family's Caribbean kitchen. My gran catered birthdays and weddings, I learned at her side from about twelve, and by fifteen I was taking orders of my own. When I chose what could travel by post, cookies were the easy decision. A good cookie has been built for tins and long journeys for generations, and a slim box through the door is simply the newest kind of tin.

If you already know who they are for, start with my cookies by post: choose six or twelve, one kind or half and half of two, and a Tuesday to Friday for them to land, from three days ahead to a year out. Collection in Peterborough is free.
How do you get cookies delivered UK-wide?
There are three ways to get cookies delivered in the UK: through the letterbox as a large letter, to the door by courier, or collected in person. The letterbox is the only one where nobody has to be in, so it is the one I built my cookie boxes around. A courier is the better choice when the box is bigger, or when the exact day matters more than the doormat.
A courier parcel is a deep box, lovely when somebody is home and a nuisance when nobody is. A letterbox box is built to the size of a large letter, rides with the everyday post and sits on the mat the way a birthday card does.
From me, you can have either. A box of six letterbox cookies goes by Royal Mail 1st Class through the letterbox. Any of my cookie boxes can go by DPD next day instead, on the day you choose, to mainland UK. Collection in Peterborough is free, and I confirm the day and the spot by email.
Whoever you order from, four questions find the best cookie delivery in the UK. Are the cookies baked for your order, or taken from stock? Will the box fit their letterbox, or can a courier come on a day you choose? Is the full price, postage included, shown before you pay? And can you read the allergen information and see a food hygiene rating before you order? I built my boxes to pass all four.
Do cookies by post fit through a UK letterbox?
Cookies by post fit through most UK letterboxes when the box is built to Royal Mail's large letter size; anything deeper or heavier usually has to be handed over. Royal Mail's limit for a Large Letter is 35.3cm long, 25cm wide and 2.5cm thick, at up to 750g. That 2.5cm is the whole design brief: one layer, laid flat, nothing stacked.
My box of six letterbox cookies is built to those numbers, so it slides through the slot and lands on the mat. The box of twelve is heavier than the large letter format allows, so it travels as a Royal Mail small parcel instead. I would rather tell you now that the dozen is not built for the letterbox than let you find out on the doorstep.
Why does the slot matter? Because anything that will not fit needs a person. Royal Mail's help pages explain that when an item cannot be got through the letter box and nobody is in, it tries again the next working day, then leaves a 'Something for you' card and takes the item back to its Customer Service Point. That is a cookie gift sitting on a shelf while its person works out when to fetch it.
A few letterboxes defeat even a slim box: stiff double draught brushes, decorative slits that have never seen a magazine, and blocks of flats where the post goes into locked pigeonholes. If you suspect one of those, choose DPD at checkout and the box travels by courier for the day you pick.
(some letterboxes were clearly designed by somebody who has never been sent a present)
Can you send cookies by post in the UK?
Yes. Cookies are among the easiest bakes to send by post in the UK, because they are dense, sturdy and happy at room temperature. Royal Mail's food guidance lists biscuits among the foods that are not perishable, alongside dried pasta and canned goods, while fish, seafood, cheese and meat are. The same guidance warns that buttercream and icing made with soft cheese, crème fraîche or sour cream make an item perishable, which tells you exactly which cookies to leave at home.
The cookies that travel best are the plain, keeping kind: butter, oat, chocolate chip and double chocolate, with little moisture to lose and nothing soft on top to smudge. The ones that struggle are the showpieces: cookies stuffed with a soft filling, sandwich cookies held together with buttercream, and anything piled high with decoration. They are glorious on a café counter and a gamble in a postbag.
Packing does the rest. Mine are packed flat in a single layer, so nothing rattles about, and each box is labelled with every ingredient, the allergens picked out, and a best-before date. If a box ever arrives less than perfect, email me and I will sort it.
(sturdy, unfussy and never travel sick: the ideal companion for a long journey)
Can I get next day cookie delivery in the UK?
Yes, as a next-day courier on a day you book, but not as order today, delivered tomorrow. From me, next day cookie delivery in the UK means DPD's next-day service: you book a Tuesday to Friday arrival at least three days ahead, I bake for that date and hand the box to DPD the day before, and DPD's next-day service carries it for your chosen day, to mainland UK.
The earliest day works like this. Order on a Monday and the first day you can pick is Thursday. Order on a Tuesday and it is Friday. Order on a Wednesday, Thursday, Friday or Saturday, and the first day is the following Tuesday. Order on a Sunday and it is Wednesday. From there you can book any Tuesday to Friday up to a year ahead, bank holidays aside, which is how a birthday in March gets sorted in October. Arrival days stop at Friday so that no box sits in a depot over a weekend.
Why not tomorrow? Because I bake for your date rather than pulling a box off a shelf, and a cookie baked for the day it travels needs a date in my diary more than an order-by-noon promise. To book next day cookie delivery, put your box in the basket, enter the address, choose DPD next day at checkout and then pick the day.
What does next day cookie delivery in the UK really mean?
Next day counts from the day a box leaves the kitchen, not the day you order, and how firm it is depends on the carrier. My DPD boxes go on DPD's next-day courier service, handed over the day before the date you chose. Royal Mail 1st Class aims to deliver the next working day, Saturdays included, and the important word there is aims.
The regulator keeps score. Royal Mail's own results for 2025/26 showed only 75.7% of First Class mail delivered the next working day, against a then-target of 93%, a shortfall Ofcom is now investigating, and the target has been 90% since 1 April 2026. Most letters were on time, but roughly one in four was not, and a cookie box rides in the same postbag as everything else.
By Royal Mail, the day you pick is my aim: I bake for it and post it in good time, but the exact day is Royal Mail's call. By DPD, it travels on a next-day courier service booked for that day, a firmer date than the ordinary post, though DPD too aims rather than guarantees. Royal Mail delivers on Saturdays, but I bake and post on my working days, so the days you can choose run Tuesday to Friday whichever carrier you pick.
For a date that matters most, choose DPD, or book a day early by Royal Mail. And if you are reading this the night before the birthday, book the soonest day and write "late, but baked just for you" on the card. A late cookie is still a cookie.
Where in the UK can cookies be delivered?
Royal Mail takes my cookie boxes anywhere in the UK at the same postage, the Scottish Highlands and islands included. Postage to Shetland or the Isles of Scilly costs exactly what it costs to the next street in Peterborough.
My DPD next day option is for mainland UK only. The checkout will not send it to Northern Ireland, the Outer Hebrides, Shetland, Orkney, the Small Isles, the Isle of Wight or the Isles of Scilly. Parts of the Highlands are only on DPD's slower service, so I do not send there by DPD either. If DPD cannot reach a postcode, the checkout says so, and Royal Mail is the way to send it.
Do delivered cookies arrive fresh, and how long do they keep?
They arrive as fresh as a posted bake can, because every box is baked for your order and sent for your date, so the clock starts in my kitchen, not on a warehouse shelf. They are at their best within five days of arriving, and every label carries a best-before date.
Store them airtight, in their own box or a tin, away from heat and damp; a sunny windowsill is not a larder, however much the cookies seem to enjoy the view. If the box looks like outlasting the household's willpower, which is rare, the freezer is the next best tin: Worcestershire County Council's food storage advice is to keep biscuits in an airtight container, and it notes that most sweet biscuits can be frozen.
Which cookies can I have delivered from Sploffin?
Five kinds of letterbox cookies are on sale all year: chocolate chip, double chocolate, butter, butter pecan, and oatmeal and raisin. They come in a box of six for £18 or a box of twelve for £34, all one flavour or two flavours split half and half. Three Christmas cookie boxes join them for the season.
The butter cookies are real butter, short enough to break clean, and the box for the person who claims not to like sweet things. The butter pecan cookies have toasted pecans through a brown-butter dough, and they contain nuts, plainly. The chocolate chip cookies have proper chocolate chunks and stay chewy in the middle. The double chocolate cookies are chocolate dough with more chocolate folded through it. The oatmeal and raisin cookies are chewy too, with the oats still doing something, which is the highest compliment I know how to pay an oat.
That works out at £3.00 a cookie in the box of six and about £2.83 in the dozen, so the dozen saves you £2 on two sixes.
Then the Christmas three. The vanilla butter cookies with glacé cherries are piped by hand with a glacé cherry set into each, and twenty-five fill a box. The snowflake gingerbread cookies come eight to a box, every snowflake iced by hand. The Christmas tree matcha cookies are sixteen little trees coloured by the matcha in the dough, so the green goes right through rather than sitting on top. Each box is £18.

Christmas orders run from 1 October to 18 December, and the boxes are baked and posted from 1 November. If you order Christmas cookies and everyday cookies together, they travel as two parcels, each on its own day with its own postage, so the everyday box never has to wait for December. I tell the full story of my Christmas cookie gifts alongside the rum fruit cake, and my guide to letterbox Christmas gifts lays out every festive box side by side.
If they like a bit of everything, the baker's choice treats box puts brownies, thick cake slices and cookies in the same slim box for £18. Chocolate people may want to read why letterbox brownies by post travel so well, while letterbox cakes by post have a guide of their own, banana bread and the Letterbox Lemon Cake included.
Which cookie gift box should I send?
Pick for the person, not the price: every box of six costs the same £18. For the traditionalist, oatmeal and raisin, which they will insist counts as breakfast. For the chocolate loyalist, double chocolate. For the friend who likes a classic with a little more to it, butter pecan. For a household that argues about flavour, half chocolate chip and half butter settles it before it starts.
(I have never met a cookie that minded the post, only people who minded sharing it)
Think about the address too. For a student in halls, send the box of six, because it goes as a large letter, and check how the halls handle post first. For a team, the dozen, or at Christmas the glacé cherry cookies at twenty-five to a box, which is 72p a cookie and enough for a whole office to pretend they only had one. For a meeting in Peterborough, my corporate lunch boxes include cookies in every size and I deliver them myself, and my guide to party food to order plans the rest of the table.
Corporate cookie gifts have a shortcut for staff birthdays. The Birthday Book lets a company book the year's birthdays in one go, in one payment. Each person gets an £18 letterbox box, with a box of six cookies among the choices, and a card in their name, posted by Royal Mail 1st Class. A small staff gift like this can be a tax-free trivial benefit if it cost £50 or less, is not cash or a cash voucher, is not a reward for work or performance and is not in their contract, though your accountant should have the last word.
How much does it cost to get cookies delivered in the UK?
A box of six of my cookies costs £21.60 delivered anywhere in the UK by Royal Mail: £18 for the cookies and £3.60 for 1st Class large letter postage. The dozen is £34 plus Royal Mail small parcel postage, and each Christmas cookie box is £21.60 delivered by Royal Mail, the same as the six. The checkout shows the full total before you pay.
Royal Mail postage is charged per box, because each box travels on its own. By DPD, I pack everything for one address into a single box priced by weight, so two or three boxes going to the same person can cost less by DPD than by Royal Mail. Once you enter a postcode, the checkout shows both carriers with their prices and picks the cheaper one for you.
One more saving: if you join my list, your first order takes 10% off the bakes. It never comes off the postage, because Royal Mail is not on my list.
Can I send cookies as a gift with a message?
Yes. Type up to 300 characters at checkout and I write them out by hand on a card inside the box, at no charge. No price and no invoice ever travel with a gift: they open the box and find cookies and your words, nothing more. Send it straight to their address; it never has to come to you first.
The checkout offers one-tap starts (Happy birthday, Thank you, Thinking of you, Get well soon, Congratulations) for anyone who freezes in front of an empty card. A cookie gift box suits the moments when flowers feel too formal and a text feels too thin: a get well soon, a thinking of you when the week has been long, a thank you to a teacher or a neighbour. My letterbox gift ideas go occasion by occasion.
The checkout takes one address per order, so each person gets their own order, their own card and their own postage. For a longer list, send me the addresses and what you would like in each, as the cookie box questions explain, and I will price the whole run at once.
Sending one now? Open the letterbox cookies page, choose six or twelve and your flavours, choose its landing day and write the card. Postage is added at checkout, or you can collect free in Peterborough. For Christmas cookies, order between 1 October and 18 December from the Christmas menu, for arrival from 1 November.
Is it safe to buy cookies from a home bakery?
Yes, when the bakery is registered and inspected. Every food business must register with its local council, and gov.uk's registration guidance spells out that this includes businesses trading from home and applies if you only sell food online. My kitchen is a registered food business rated 5 for food hygiene, and the rating badge is in the footer of every page here.
Allergens come next. For food bought online, allergen information must be available before you finish buying and again when the food is delivered. Each box I send carries its full ingredient list on the label, with every allergen picked out, and I will happily send you that list before you order. The butter pecan cookies contain pecans. All 14 major allergens, nuts among them, are handled in my home kitchen, so nothing I bake can promise to be free of traces. If you are buying for someone with an allergy, my allergen information is the place to start, and if it is severe, talk to me before you order. I do not post a vegan or gluten-free cookie.
How do I order cookies delivered from Sploffin?
Ordering cookies delivered UK-wide is quick. Open the page, choose six or twelve and one kind or two, add the box to your basket and enter the address it should go to. Choose Royal Mail 1st Class, DPD next day or free collection in Peterborough, pick the day, add your card message and pay on Stripe's secure checkout. Then I bake for your date, label the box, pack it flat and send it on its way.
The best cookie deliveries are the ones nobody has to wait in for. Picture an ordinary Thursday: a slim box on their mat, your words inside in my handwriting, and a kitchen smelling of butter and chocolate before the kettle has boiled. Choose your letterbox cookies, pick a Tuesday to Friday from three days ahead, and I will bake them for the day.
Questions people ask
- Can you send cookies through the post in the UK?
- Yes. Royal Mail lists biscuits as non-perishable food, so dense, sturdy cookies such as butter, oat and chocolate chip travel well by post. Avoid fillings and icings made with soft cheese, crème fraîche or sour cream, which Royal Mail says make food perishable. My box of six goes as a large letter straight through the letterbox, anywhere in the UK, so nobody has to be in.
- Do cookie boxes fit through the letterbox?
- A slim one does. A Royal Mail large letter can weigh up to 750g and measure 35.3cm by 25cm by 2.5cm deep, and a box built to it is made to slide through most UK letterboxes, so nobody needs to be in. My box of six is built that way. The dozen is heavier than the large letter format allows, so it travels as a small parcel instead.
- Can I get cookies delivered the next day in the UK?
- Yes on a day you book, though not order today for tomorrow. Pick DPD next day at checkout and any Tuesday to Friday at least three days ahead. I bake for that date and hand the box to DPD the day before, and its next-day service carries it for the day you picked. DPD next day covers mainland UK only.
- How much does it cost to send cookies by post in the UK?
- My box of six cookies is £18, and Royal Mail 1st Class large letter postage is £3.60, so it reaches any UK address for £21.60. The dozen is £34 plus small parcel postage. DPD next day is priced by the weight of everything going to one address, and the checkout shows both carriers with their prices before you pay.
- How long do posted cookies stay fresh?
- At their best within five days of arriving, and every box I post carries its own best-before date. The cookies are baked for your order and posted for your date, so the clock starts in my kitchen, not on a warehouse shelf. Store them airtight in their box or a tin, away from heat and damp, and put the lid back after every raid.
- Can I send cookies as a gift with a message?
- Yes. Type up to 300 characters at checkout and I write your message by hand on a card in the box, at no extra cost. No price or invoice ever goes in with a gift. Each address is its own order, so every person gets their own card, and for a long list I can price the whole run at once.
- Do you deliver cookies to the Scottish Highlands and islands?
- Yes, by Royal Mail, at the same postage as anywhere else in the UK: a large letter for the box of six and a small parcel for the dozen. My DPD next day option covers mainland UK only, so the Scottish islands and the parts of the Highlands DPD serves on a slower service go by Royal Mail, where the day you pick is an aim.
