Night-shift treat planners
You want a biscuit to take on a break alongside the food you have planned for your shift, rather than relying on it as a meal or an alertness aid.
Who is this choice for?
Cocoa-percentage checkers
You want to know how much chocolate the biscuit contains and whether the chocolate itself has a stated cocoa-solids percentage. Those figures measure different things.
Shoppers with ingredient restrictions
You need to compare all-butter recipes with free-from options and read the exact pack for ingredients such as oats and soya.
What should you check before choosing?
Start with the biscuit and chocolate you actually want, then check the portion and ingredient list for the break you are planning.
| Priority | What to check | Your needs |
|---|---|---|
| Biscuit type | Check whether the base is shortbread or another biscuit, such as a digestive. Look for the chocolate type in the ingredient list rather than relying on the front-of-pack description. | If I specifically want shortbread, a dark-chocolate digestive will not make the same choice for me. |
| Chocolate detail | Read the percentage of chips or chunks separately from the cocoa-solids percentage in that chocolate. The examined Sainsbury’s and M&S chunk shortbreads each list 19% dark-chocolate chunks and 39% minimum cocoa solids in the chocolate, according to their product listings. | I want a stated cocoa percentage, rather than assuming that “dark” or a larger chunk percentage means 70% cocoa chocolate. |
| Break-time portion | Compare per-biscuit nutrition as well as pack size. Sainsbury’s lists 100 kcal per round for its chocolate-chip shortbread and 115 kcal per round for its Taste the Difference chunk variety; Waitrose lists 356 kcal per shortbread for its bakery four-pack. | For a work break, I want to know what one biscuit represents before packing a portion. NHS shift-worker guidance suggests planning food and considering smaller snacks or a light meal during breaks. |
| Ingredients and allergens | Read the current pack’s full ingredient and allergen information. M&S lists wheat, milk and soya in its examined all-butter rounds; Morrisons describes its examined vegan shortbread as free from gluten, milk and egg, but lists oats and soya. | Dark chocolate alone does not tell me whether a shortbread meets my ingredient requirements. |
What is easy to misread?
-
“Dark” means high-cocoa chocolate
The examined Sainsbury’s and M&S chunk shortbreads each list 19% chocolate chunks, while specifying 39% minimum cocoa solids in the chocolate. Neither figure says the finished biscuit is 70% cocoa.
Check the cocoa-solids statement for the chocolate separately from its share of the biscuit. If a particular cocoa percentage is essential, look for that figure on the chocolate label.
-
Dark-chocolate shortbread is dark-only or dairy-free
Waitrose’s examined bakery shortbread combines milk- and dark-chocolate chunks, while the examined M&S dark-chocolate rounds contain butter.
Check the whole ingredient and allergen list for the exact bakery item or packaged biscuit.
-
Pack count tells you the portion size
A bakery shortbread and a smaller packaged round can have different per-biscuit nutrition. The examined Waitrose four-pack lists 356 kcal per shortbread; the examined Sainsbury’s packaged rounds list 100 or 115 kcal each.
Compare the current label’s per-biscuit and per-100 g figures when deciding what to take to work.
Which brand ranges are relevant?
These product-line examples show why a chocolate-chip description, a cocoa percentage and an ingredient claim need to be read separately.
Sainsbury’s
Its examined own-label range includes an everyday chocolate-chip shortbread and a Taste the Difference chocolate-chunk shortbread.
- Sainsbury’s lists 14% dark-chocolate chips and 100 kcal per round for the everyday product, and 19% chunks and 115 kcal per round for the chunk variety.
- Both listings state 39% minimum cocoa solids in the chocolate; neither chunk or chip percentage describes the cocoa content of the biscuit.
M&S
Its examined all-butter Scottish shortbread rounds contain dark Belgian chocolate chunks.
- M&S lists 19% dark-chocolate chunks and 39% minimum cocoa solids in that chocolate.
- The examined rounds contain wheat, milk and soya; M&S also says they are unsuitable for people with a nut or peanut allergy.
Walker’s
The examined 150 g pack is an all-butter shortbread with dark-chocolate chips.
- The Walker’s listing carried by Waitrose states that dark-chocolate chips make up 11% of the recipe.
- If the cocoa percentage matters, check the pack for a separate cocoa-solids statement rather than treating 11% as that figure.
Waitrose
Its examined bakery four-pack combines Belgian milk- and dark-chocolate chunks.
- Waitrose lists 15% milk-chocolate chunks and 7% dark-chocolate chunks.
- At a listed 356 kcal per shortbread, this bakery item is a different per-biscuit portion from the examined smaller packaged rounds; it is not a dark-only recipe.
Dean’s
The examined 130 g pack contains chocolate-chip shortbread rounds.
- Dean’s lists 15% mini chocolate chips and includes margarine and salted butter in the recipe.
- Check the exact pack if dark chocolate or a particular cocoa percentage is a requirement; the cited description does not identify the chips as dark chocolate.
Morrisons
Its examined 150 g vegan chocolate-chip shortbread is a free-from alternative to the examined all-butter recipes.
- Morrisons lists 11% Belgian dark-chocolate chips and describes the product as free from gluten, milk and egg.
- It contains oats and soya. Check the supplied pack against your particular ingredient requirements.
A Joybuy biscuit option
The Joybuy option here is a dark-chocolate digestive twin pack, not shortbread. Consider it for a planned break only if a different biscuit base suits you.

Common questions
Does dark-chocolate shortbread necessarily contain high-cocoa chocolate?
No. Sainsbury’s examined chocolate-chunk shortbread lists 19% chocolate chunks, with 39% minimum cocoa solids in the chocolate. The first percentage is the chunks’ share of the biscuit; check the particular pack for the cocoa figure you want.
Can shortbread replace a night-shift meal or keep me alert?
Do not plan shortbread as a meal replacement or an alertness strategy. NHS shift-worker guidance recommends bringing planned food and considering smaller snacks or a light meal during breaks.
Is vegan or free-from shortbread suitable for every ingredient restriction?
No. Morrisons describes its examined vegan shortbread as free from gluten, milk and egg, but its ingredient information lists oats and soya. Check the supplied package against your particular requirements before eating.
How should I compare a bakery shortbread with packaged rounds?
Compare the current labels per biscuit and per 100 g, not pack count alone. Waitrose lists 356 kcal per shortbread for its examined bakery four-pack, while Sainsbury’s lists 100 or 115 kcal per round for its examined packaged varieties; these are different portion formats.
Does England’s school-food guidance prevent an adult from buying shortbread for a night shift?
No such restriction follows from the Department for Education’s school-food guidance, which concerns food provided in state-funded schools in England, not an adult’s personal snack. Its guidance updated on 14 September 2026 described proposed changes from September 2027 as subject to parliamentary approval. Separate England retail-promotion rules cover certain products and businesses; they do not, by themselves, classify each shortbread listed here.
