One-treat shoppers
If you only want one piece, check that the purchasable item is a single bar or slice rather than a multipack or a case.
Who is each format for?
Plain-shortbread shoppers
If caramel and chocolate are not what you want, look at traditional shortbread fingers—but distinguish an individually wrapped finger from a listing for a whole case.
Shoppers checking allergens
Recipes and precautionary warnings differ. Read the label on the supplied pack rather than judging suitability from the word “shortbread”.
What should you check?
Start with the number of pieces you want, then compare the style of shortbread, the supplied label and any storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Purchase quantity | Check whether the listing is for one 50g bar or slice, four pieces, or a case of wrapped fingers. An individually wrapped portion is not necessarily sold on its own. | I only want one treat, so I need to know how many pieces I must buy. |
| Shortbread style | Check whether the product is plain shortbread or a millionaire’s slice with caramel and chocolate. A chocolate shortbread multipack is not necessarily a caramel-layered slice. | Am I after a plain biscuit, or do I want the caramel-and-chocolate layers? |
| Ingredients and allergens | Read the supplied pack’s ingredients and allergen statements. M&S says its 50g Millionaire Shortbread is unsuitable for people with nut or peanut allergies; do not apply that statement to other products. | If an ingredient or warning matters to me, I need to assess the particular item I receive. |
| Extra portions | For a multipack, check the instructions for keeping it after opening. Waitrose recommends an airtight container and consumption within two days for the quality of its opened four-slice millionaire’s shortbread. | Will I use the remaining slices within the pack’s storage guidance? |
Common buying mistakes
-
Confusing a wrapped finger with a one-finger purchase
Walker’s lists its wrapped 20g fingers in a case of 240, while Dean’s lists approximately 80 wrapped 17g fingers per case.
Check the quantity you must buy before treating either listing as an alternative to one bar.
-
Choosing a multipack when you only want one piece
Waitrose’s millionaire’s shortbread listing contains four slices, leaving additional portions to keep after opening.
Choose the format around the number of pieces you will use, and check the pack’s storage instructions if you buy several.
-
Assuming millionaire’s shortbread has uniform allergen warnings
Ingredients and product-specific warnings can differ between bars and slices. M&S identifies its 50g product as unsuitable for people with nut or peanut allergies.
Read the label on the supplied item before eating; a similar product name does not establish the same allergen information.

Questions about single portions
Is an individually wrapped finger sold as one item?
Not in the Walker’s and Dean’s listings described here. Walker’s lists 240 wrapped 20g fingers per case, and Dean’s lists approximately 80 wrapped 17g fingers per case. Check the purchasable quantity, not just the size of each packet.
What is the difference between a plain finger and a millionaire’s slice?
The single millionaire’s shortbread slices discussed here have a shortbread base with caramel and chocolate; a plain finger is the option to consider when you do not want those toppings. Check the listing’s pack quantity, as the wrapped plain fingers described here are sold by the case.
How should I keep leftover millionaire’s shortbread slices?
Follow the instructions on the particular pack. For its four-slice millionaire’s shortbread, Waitrose recommends an airtight container after opening and consumption within two days for quality.
Which allergen information matters when choosing a bar?
Read the supplied product’s ingredients and precautionary statements rather than assuming similar-looking bars have the same warnings. M&S states that its 50g Millionaire Shortbread is unsuitable for people with nut or peanut allergies; that warning describes that product, not every shortbread bar.
