Lower-fat dessert planners
If the custard will be served with biscuits, compare fat and sugars per 100g rather than relying on the low-fat wording alone. Check the ingredients and storage instructions on the pack you buy.
Who is choosing?
Custard-cream biscuit bakers
If your dough calls for custard powder, ingredient format matters more than finding a ready-to-serve tin. Good Housekeeping’s custard-cream biscuit recipe uses custard powder in the dough.
Small-batch home bakers
If you need only a little prepared custard, match the pack to your recipe and serving plans. Opened custard needs refrigeration and must be used within the period stated on its label.
What matters when buying?
Start with the recipe’s ingredient format: custard powder for dough that specifies powder, or prepared custard for serving and recipes that expressly call for it. Then compare nutrition and the amount you are likely to use.
| Concern | What to check | Who this matters to |
|---|---|---|
| Fat and sugars | Compare both figures per 100g on the current pack, alongside ingredients relevant to you. Sainsbury’s lists 1.8g fat and 11.1g sugars per 100g for Ambrosia Low Fat Custard Can 400g. | If I am serving custard with biscuits, I want to weigh fat against sugars before choosing a pack; about 42% of consumers put this nutrition comparison first. |
| Recipe format | Read the ingredient list: Good Housekeeping’s custard-cream biscuit dough uses custard powder, not ready-to-serve custard. | When I am baking custard-flavoured biscuits, I need the ingredient named by the recipe so I can follow it as written; about 33% of consumers prioritise the correct format. |
| Pack size and storage | Estimate how much you will use, then check the specific pack’s refrigeration and post-opening instructions. | For a small bake, I would rather choose an amount I can finish within the labelled period; about 25% of consumers place pack size and storage first. |
Buying mistakes to avoid
-
Buying a tin when the dough calls for powder
Ready-to-serve custard and custard powder have different roles. Good Housekeeping’s custard-cream biscuit recipe uses powder in its dough; a prepared tin should not be assumed to work as a direct replacement.
Check the recipe before shopping. Choose powder where it specifies powder, and prepared custard for serving or where the recipe expressly names it.
-
Comparing only the low-fat wording
A low-fat label does not tell you the product’s sugars figure. Sainsbury’s lists both 1.8g fat and 11.1g sugars per 100g for Ambrosia Low Fat Custard Can 400g.
Compare fat and sugars per 100g on the current labels of the products you are considering.
-
Opening more custard than you can use
A larger carton may leave custard after a small baking session. Post-opening instructions vary: Marks & Spencer says to refrigerate its Silky Smooth Custard and eat it within two days.
Work out the quantity needed for baking and serving, then follow the storage period on the exact pack.

Relying on an older online ingredient list
Ingredient and nutrition details matter when comparing products or avoiding particular ingredients, and the pack you receive is the one you will use.
Check its ingredients, allergens, nutrition panel and storage instructions before preparing or serving it.
Brands to consider
Ambrosia
Ambrosia has a Low Fat Custard Can 400g for ready-to-serve use and a larger Light Devon Custard 1kg carton for serving plans that need more.
- The named low-fat product provides a tinned option; the light carton is a different format.
- Neither prepared format should be assumed to replace custard powder in biscuit dough. Check the current pack for nutrition and post-opening instructions.
Bird’s
Bird’s Original Custard Powder is an ingredient route for recipes that specify powder rather than a ready-to-serve tin.
- Good Housekeeping’s custard-cream biscuit recipe uses custard powder in its dough.
- The powder alone does not establish the fat or sugar content of a finished biscuit or filling.
Sainsbury’s
Sainsbury’s ambient custard listing includes Ambrosia Low Fat Custard Can 400g and Sainsbury’s Ready To Eat Lighter Custard 500g.
- The listing offers different prepared-custard formats to compare.
- Check the own-label product’s current nutrition and ingredients before treating its lighter wording as equivalent to the Ambrosia can.
Tesco
Tesco’s tinned-custard listing distinguishes Tesco Ready To Serve Custard from Ambrosia Low Fat Custard.
- The separate listings make it possible to identify which product is expressly labelled low fat.
- Do not assume Tesco Ready To Serve Custard has the same nutrition profile; compare the exact labels.
M&S
M&S Silky Smooth Custard is a 400g whole-milk prepared custard to consider when choosing a custard to serve with dessert.
- Marks & Spencer states 3.7g fat per 100g, giving a product-specific figure for comparison.
- It is not the low-fat tinned option in this selection; its label says to refrigerate and eat it within two days of opening.

Ambrosia Low Fat Custard 400g
For serving with baked biscuits or using where a recipe specifies prepared custard, this is a 400g low-fat can that can be served hot or cold. Check the current pack’s nutrition figures before comparing it with other custards, and follow its storage instructions after opening.

Ambrosia Light Devon Custard 1kg
If you need a larger amount of prepared custard for serving or a recipe that specifies it, this light custard comes in a 1kg carton, not a tin. Plan how you will use the remainder and follow the pack’s refrigeration and post-opening instructions.
No image available
Bird’s Custard Powder 350g
For biscuit dough that calls for custard powder, this is the relevant 350g ingredient format. It is not ready-to-serve tinned custard, and the finished biscuit’s nutrition depends on the full recipe. Check the pack’s allergen information if needed.
Common questions
Can I replace custard powder with low-fat tinned custard in biscuit dough?
Do not assume they are interchangeable. Good Housekeeping’s custard-cream biscuit recipe uses custard powder in the dough, whereas Ambrosia Low Fat Custard Can is prepared custard for hot or cold use. Follow the ingredient format specified by your recipe.
How should I compare fat and sugars in prepared custard?
Compare both figures per 100g on the current packs. Sainsbury’s lists 1.8g fat and 11.1g sugars per 100g for Ambrosia Low Fat Custard Can 400g; check the pack you buy before using those figures to choose between products.
How long can I keep custard after opening it?
Follow the instructions on the exact pack and refrigerate it where directed. Opened-use periods differ between products: Marks & Spencer instructs buyers to refrigerate its Silky Smooth Custard and eat it within two days.
Is low-fat custard suitable if I avoid milk?
Do not treat low fat as meaning milk-free. Ambrosia Low Fat Custard Can is a dairy custard; check the ingredients and allergen information on the current pack of any product you are considering.
