People sharing snacks in the car
A larger classic pack may suit several passengers. Tesco instructs buyers to keep its 400 g custard creams in an airtight container after opening, so plan how to store an unfinished pack.
Who is choosing?
Chocolate-focused biscuit buyers
If chocolate type matters more than the classic filling, read the coating description closely. M&S calls its coated custard creams milk chocolate, not dark chocolate, and specifies storage away from sunlight.
Buyers checking allergens
Check the physical pack before travel when wheat, milk, soya or sesame matters to you. Ingredients and precautionary allergen statements differ between products and may change.
What should you check?
Decide whether chocolate type or the custard-cream format matters most, then check storage, allergens and pack size for the journey.
| Priority | What to check | Your needs |
|---|---|---|
| Chocolate type | Read the exact coating description and any declared cocoa-solids figure. M&S describes its 64 g coated custard creams as milk chocolate containing at least 28% cocoa solids; that does not make them a dark-chocolate product. | I want to know whether the chocolate is actually dark, rather than buying a coated biscuit on the strength of its appearance. |
| Car storage | Follow the pack’s cool, dry storage directions and keep M&S coated custard creams out of sunlight. For chilled picnic food, GOV.UK’s heatwave advice recommends a separate cool bag kept closed until needed; it does not say these biscuits require refrigeration. | Will I be able to keep the pack away from a sunny dashboard or a hot parked car during the journey? |
| Allergens | Read the current pack’s ingredients, emphasised allergens and any ‘may contain’ statement. Check the exact product rather than relying on a saved listing. | Wheat, milk, soya or sesame may affect which pack I can bring for the passengers travelling with me. |
| Pack and portions | Compare the stated pack weights: Tesco’s classic custard creams are 400 g, M&S Extra Cream are 165 g, and its coated snack is 64 g. When comparing nutrition, use the same basis: Tesco gives 59 kcal per biscuit, which is not a per 100 g figure. | For several people, I need to judge how far a pack will go; for one snack, a smaller format may be enough. |
Mistakes to avoid
-
Assuming ‘chocolate-coated’ means dark chocolate
M&S identifies its coated custard creams as milk chocolate with at least 28% cocoa solids. A chocolate coating alone does not establish the dark flavour you may be looking for.
For a dark-specific purchase, look for an explicit dark-chocolate description on the current pack or product page.
-
Leaving a coated pack in direct sun
M&S directs buyers to store its coated custard creams somewhere cool and dry, away from sunlight. A sunny car is a poor place to leave that pack.
Keep the biscuits shaded, and use a separate cool bag for chilled picnic food as advised in GOV.UK’s heatwave guidance.
-
Using an old allergen list
The ingredients relevant to an allergy depend on the exact product and its current recipe. Different custard creams list different allergens or precautionary statements.
Read the physical pack before packing it, including any ‘may contain’ information.
-
Applying school-food rules to a private trip
The Department for Education’s school-food standards concern food and drink provided to pupils on school premises at state-funded schools in England. That is a different setting from buying snacks for a private road trip.
Use the applicable school guidance when providing food in that school setting; for a private trip, check the product’s label and storage directions.
Brand and retailer references
These examples show how classic, extra-cream and coated products differ; a brand name alone does not establish chocolate type or current availability.
Tesco
Tesco lists a 400 g vanilla-filled custard-cream sandwich biscuit.
- Its product information gives nutrition per biscuit and calls for cool, dry storage and an airtight container after opening.
- The classic biscuit is not described as a chocolate or dark-chocolate variety.
M&S
M&S lists both 165 g Extra Cream Custard Creams and a 64 g chocolate-coated snack.
- The two listings let you choose between extra vanilla filling and a chocolate-coated format.
- The coated product is labelled milk chocolate with at least 28% cocoa solids, not dark chocolate, and should be stored away from sunlight.
Fox's
Tesco’s listing identifies a 200 g pack of Fox's classic custard creams.
- The listing names milk, soya and wheat as allergens.
- It is not a dark-chocolate variety. The cited Tesco listing marks the pack out of stock, so check its current listing before planning to buy it.
McVitie's
A Joybuy listing identifies McVitie's Tasties Custard Creams in a 300 g pack.
- The listed ingredients identify wheat and milk, with a possible sesame cross-contact statement.
- The listing says the product is no longer available and does not identify it as a dark-chocolate variety.
Joybuy product options
These options cover a gluten-free custard cream and a wafer for anyone flexible about biscuit format. Neither product name identifies a dark-chocolate custard cream.

BOURBON Soy Milk Wafers 112.8g
This wafer is an alternative road-trip biscuit only if you are flexible about the custard-cream format. The pack is 112.8g; check its current label for chocolate type, allergens and storage directions if those details matter to your choice.
No image available
Schar Gluten Free Custard Creams 125g
For a custard-cream biscuit rather than a coated snack, this is a gluten-free 125g pack. Its name does not describe a dark-chocolate variety; check the current pack for ingredients, allergens and storage directions.
Common questions
Does a chocolate-coated custard cream count as dark chocolate?
Not on the strength of the coating alone. M&S describes its coated custard creams as milk chocolate containing at least 28% cocoa solids; check an exact product’s current label for an explicit dark-chocolate description if that is what you want.
How should I carry coated custard creams on a warm journey?
Keep M&S coated custard creams somewhere cool and dry and out of sunlight, as its storage directions specify. GOV.UK advises a separate, closed cool bag for chilled picnic food; that advice does not mean shelf-stable biscuits need refrigeration.
Which allergens should I check before packing custard creams?
Read the exact physical pack before travel. Product listings identify wheat and milk in some classic custard creams, while the Tesco listing for Fox's names milk, soya and wheat; check precautionary statements such as ‘may contain’ as well.
Do school-food rules restrict custard creams on a private road trip?
The Department for Education’s school-food standards, updated in September 2026, apply to food and drink provided to pupils on school premises at state-funded schools in England. They do not establish a general restriction on buying custard creams for a private road trip.
