Choose plain digestives for a recipe written around a digestive crumb base; choose custard creams when their vanilla-flavoured filling is meant to be part of the dessert. The filling affects how the crumbs bind, so follow a recipe developed for the biscuit you use rather than copying its butter quantity from the other type. Check the exact pack’s ingredients when baking for someone who needs to avoid an ingredient.
If you are crushing biscuits for a cheesecake or similar base, choose the biscuit type before settling on the recipe’s butter quantity. Dr. Oetker’s digestive-base method and Jane’s Patisserie’s custard-cream method treat the two bases differently.
Custard creams bring a vanilla-flavoured sandwich filling into the crumb mixture. That makes them a different ingredient from an unfilled digestive when the biscuit’s flavour is part of the dessert.
Check the particular pack before serving a bake to someone who needs to avoid an ingredient. The Tesco and Sainsbury’s custard-cream examples list wheat and milk ingredients; ASDA’s digestive listing contains wheat and says it may contain milk. Those examples do not establish the ingredients of every biscuit in either category.
Choose when: The recipe calls for digestives and you want its other ingredients to lead the flavour.
Trade-off: An unfilled digestive will not contribute a custard cream’s vanilla-flavoured filling.
Choose when: The vanilla-flavoured filling is an intended part of the dessert.
Trade-off: Jane’s Patisserie explains that the filling affects a cheesecake base when mixed with melted butter, so a digestive-base method is not a direct substitute.
| Priority | What to check | Your needs |
|---|---|---|
| Base recipe | Check which biscuit the method specifies and use its biscuit and butter quantities. Dr. Oetker’s particular digestive-base method calls for 250 g digestives and 125 g unsalted butter; that is not a universal ratio. | I want the crumb mixture to match the method I am following, rather than swapping in a filled biscuit without adjusting the recipe. |
| Biscuit flavour | Check whether the biscuit is unfilled or has a vanilla-flavoured sandwich filling. Tesco describes its custard creams as filled sandwich biscuits. | If I want vanilla filling in the dessert, I would choose a recipe written for custard creams. Otherwise, I would look at the digestives specified by my base recipe. |
| Ingredients | Read the exact pack’s ingredients and allergen statements. The Tesco custard-cream listing includes wheat and milk ingredients; the ASDA digestive listing contains wheat and says it may contain milk. | Someone eating my bake needs to avoid an ingredient, so the particular biscuit pack matters more than assumptions about its category. |
| Pack quantity | Compare the recipe’s required biscuit weight with the pack’s net weight. Decide whether a partly used pack suits another planned bake. | I need enough biscuits for the base without choosing a pack size solely by its appearance. |
Jane’s Patisserie explains that custard-cream filling melts alongside the butter in a cheesecake base. A butter quantity from a digestive-base recipe therefore should not be assumed to give the intended custard-cream mixture.
Pick the biscuit first, then follow a base recipe developed for that biscuit type.
A plain digestive and a filled digestive are not the same ingredient. Joybuy’s McVitie’s Digestives Creams Vanilla listing, for example, describes a vanilla cream layer between digestives.
Read the full product name and description before matching a pack to an unfilled-digestive recipe.
Ingredient and precautionary statements vary between products. ASDA’s digestive listing, for example, says the biscuits contain wheat and may contain milk.
When an ingredient must be avoided, read the label on the exact pack you will use before adding the biscuits to the bake.
These examples help distinguish biscuit types and ingredient statements; a brand name alone does not tell you which recipe fits a particular pack.
McVitie’s Original Digestives are an example to consider for a recipe calling for plain digestives.
Tesco Custard Cream Biscuits 400G are a vanilla-filled sandwich biscuit for a recipe written around custard creams.
ASDA Digestive Biscuits 400g are a plain-digestive example.
Sainsbury’s Custard Creams 200g are another filled-biscuit example.
The M&S biscuit range includes digestives and custard creams, so select the particular type named by your recipe.
These Joybuy options cover one custard cream and one digestive. Match the biscuit and its stated variant to your recipe before choosing a pack.

Consider these when a recipe calls for custard creams rather than plain digestives. The product name identifies a 125g gluten-free custard-cream pack; follow the chosen recipe’s biscuit and butter quantities and check the pack’s full ingredient information for the people eating the bake.

Consider these for a recipe that calls for digestives, checking whether this named variant suits the intended bake. The product name identifies a 400g sugar-free digestive pack; check its ingredients and allergen statements on the pack before use.
Do not assume the quantities are interchangeable. Dr. Oetker’s specific digestive-base method uses 125 g unsalted butter with 250 g digestives, while Jane’s Patisserie explains that custard-cream filling also melts into a cheesecake crumb mixture. Follow a method written for the biscuit you use.
Dr. Oetker’s digestive-base method uses a food processor to crush the biscuits finely before mixing them with melted butter and pressing them into a springform tin. That describes its particular method, not a requirement for every biscuit bake.
No. Tesco’s listed custard creams include wheat and milk ingredients, while ASDA’s listed digestives contain wheat and may contain milk. Read the ingredients and precautionary statements on the exact pack you will use.
GOV.UK explains that a best-before date concerns quality, whereas a use-by date concerns safety; it gives stale biscuits as an example of a quality change. Follow the storage instructions on the pack as well.
