Mix and match your favourite Signature SlicesYOUR FLAVOURS. YOUR COMBINATION.
A whole slab gives you more of one favourite. If you fancy a little variety instead, build a box of individual Signature Slices and choose the exact flavours you want.
Choose 4, 9 or 16 slices from the available flavours and put together your perfect combination — for sharing, gifting or enjoying at home.

Signature Slices brings together our cookie bars, brownies, blondies, tiffin and other favourite bakes. A whole slab is the larger, uncut format: one flavour, delivered by post for you to divide into the portions you want.
Looking for postal cookie bars or brownies by post for a group? Whole slabs let you choose generous dessert squares or smaller sharing bites, without having to bake them yourself.
Love a chocolate-filled cookie bar? Prefer a brownie, blondie or biscuit-packed tiffin? The whole-slab range brings these different bakes together, so you can start with the type you enjoy and find a flavour that suits you.
Browse all whole slabs to see the range, including rocky road and millionaire’s shortbread. Each product page describes that bake’s texture, ingredients and filling.
Keep it generous with dessert squares, go smaller for a shared spread, or cut a mixture of sizes. A whole slab gives you the freedom to decide how you want to serve it.
The animation shows nine squares as one serving idea. Portion sizes and the number of pieces are up to you; check the details of your chosen bake when planning how much to order.
FRESHNESS & DELIVERY
Whole cookie bar trays are baked fresh for you. Order Monday to Thursday before 2pm and we aim to dispatch within 24 hours.
Keep rocky road and tiffin in the fridge and enjoy within 7–10 days. Take it out at least an hour before serving so the chocolate softens.
Cookie bar slabs can be frozen for up to 3 months. Defrost at room temperature for around 4 hours before serving.

We are a UK postal bakery. Whole slabs and ready-cut slices can have different preparation times; dispatch is when an order leaves us, not its arrival date. Check the order and delivery guide and the available checkout options when planning for a birthday, gift or gathering.
Once your order arrives, follow the storage guidance supplied with your bakes. Cut your whole slab into the portions you want and enjoy at home or share with others.

A FEW GOOD QUESTIONS
Choosing your bake, cutting your portions and enjoying every piece.
It is a whole, uncut bake from our Signature Slices collection. Choose a flavour, then divide the slab into your own portions. Signature Slices is our collection name and includes several types of bake, not just cookie bars.
The range includes cookie bars, brownies, blondies, rocky road, tiffin, millionaire’s shortbread and other bakes. Use the whole-slab list on this page to find a flavour, then check its product page for current availability.
A whole slab is the uncut format. The animation shows nine squares as one serving idea; you can cut larger dessert portions or smaller bites instead. Check the chosen product’s details when planning servings.
No. A whole slab works for dessert at home, an office gathering or a celebration. It is a way to order more of a flavour you enjoy and decide how to portion it. Follow the storage guidance for any pieces you keep for later.
Each whole slab is one flavour. Choose separate slabs for a larger spread, or build a Signature Slices Bundle Box if you would rather mix individual slices in one box. The bundle section above lets you explore that option.
Follow the storage information on our website and any instructions supplied with your bake. Use the guidance for your specific product, especially if you plan to enjoy it over more than one occasion.
Yes. Where the flavour is offered in both formats, an individual Signature Slice is the bakery-cut option. Browse the Signature Slices collection if you would prefer a ready-cut portion or want to try a flavour before ordering a whole slab.
Yes. Choose individual slices for ready-cut portions or whole slabs to divide yourself. Mix flavours for birthdays and other celebrations, check the ingredients and allergens for each bake, and read our order and delivery guide before planning around a specific date.
Yes. Clever Cookie is a UK postal bakery, and you can order whole slabs online for delivery. Check the delivery options available for your address at checkout and read our order and delivery guide before ordering for a particular date.
This page focuses on whole slabs, including cookie bars, brownies and blondies. A whole slab arrives uncut for you to portion. Individual Signature Slices are available separately if you prefer a ready-cut treat.
Whole slabs can be ordered for birthdays, office gatherings or a treat at home. Plan ahead using our delivery guide and check the delivery address carefully. Dispatch and arrival are different stages, so do not assume that a dispatch date is the day your order will arrive.
