A custard cream can be a sweet post-gym snack, but it is a different choice from a snack selected for its protein content: Tesco, Sainsbury’s and Asda list just 0.6–0.7 g protein per biscuit. If a defined biscuit portion matters, check how many biscuits are in an individual pack; if protein content is the priority, compare the nutrition per portion of a protein-containing alternative instead.
Who is this choice for?
Gym-goers who want a sweet biscuit
If you fancy custard creams after exercise, decide whether the biscuit is simply a treat or whether you want the snack to contain a meaningful amount of protein. Tesco, Sainsbury’s and Asda list 0.6–0.7 g protein per biscuit.
Snackers who prefer a defined portion
An individual packet may be easier to carry than an open multipack, but individual does not mean one biscuit or one bar. Thompsons Food Service describes Crawford’s assorted mini packs, which include a custard-cream option, as containing three biscuits per packet.
School-food buyers in England
A personal post-gym purchase and food supplied at school are different decisions. GOV.UK says food served in maintained schools and academies in England must meet school food standards; check the applicable service context rather than treating those standards as a rule for personal snacks.
What should you check?
Start with the job you want the snack to do, then compare the nutrition for the portion you would actually eat and the format you would carry.
| Priority |
What to check |
Your needs |
| Snack purpose |
Decide whether you want a sweet biscuit or are choosing food around another exercise session. A review published in Nutrients discusses carbohydrate intake during limited recovery and the possible role of adding protein when carbohydrate intake is sub-optimal; it does not make one snack necessary after every workout. |
After a demanding session, I want to consider what I am eating before my next one. On another day, I may simply want a biscuit. |
| Protein per portion |
Read protein for the amount you intend to eat, not just the ingredient list. Tesco and Sainsbury’s each list 0.7 g per biscuit; Asda lists 0.6 g per biscuit. |
If protein content is why I am buying a post-gym snack, I want to compare the full portion rather than assume a custard cream serves that purpose. |
| Pack format |
Check biscuits per packet and the nutrition for that packet. Thompsons Food Service describes Crawford’s assorted mini packs as three biscuits per pack, not a single bar. |
I want something I can carry as one packet, while knowing how many biscuits I will have when I open it. |
| Nutrition label |
Compare sugars and saturates using the same portion basis. Per biscuit, Tesco lists 3.4 g sugars and 1.5 g saturates; Sainsbury’s lists 3.3 g and 1.2 g; Asda lists 3.4 g and 1.5 g. |
When I choose a sweet snack, I want to know what is in the number of biscuits I plan to eat. |
| School setting |
For food supplied at a maintained school or academy in England, check the school food standards and the precise service context. GOV.UK identifies those settings as within the standards’ scope. |
If I am buying for a school rather than myself, I need to assess the relevant school-food requirements separately. |
Common buying mistakes
-
Treating milk ingredients as a protein comparison
Ingredients alone do not tell you how much protein a serving contains. Tesco and Sainsbury’s list 0.7 g per custard cream, while Asda lists 0.6 g.
Compare protein on the nutrition panel for the portion you expect to eat.
-
Assuming a mini pack means one bar
The Crawford’s custard-cream option described by Thompsons Food Service comes in an assorted mini-pack format with three biscuits per packet.
Check both the biscuit count and the on-pack nutrition for the whole packet.
-
Applying school-food rules to a personal snack
GOV.UK’s school food standards concern food served in maintained schools and academies in England. They do not describe a general ban on buying custard creams for yourself.
For a school purchase, check the country, school setting and service context before deciding what can be supplied.
Relevant brand references
These product listings illustrate the difference between conventional custard-cream packs and an individually packed biscuit portion; they are not a list of Joybuy products.
Tesco
Tesco Custard Cream Biscuits come in a 400 g pack of vanilla-filled sandwich biscuits.
- Tesco lists 59 kcal, 8.4 g carbohydrate and 0.7 g protein per biscuit.

Questions about post-gym custard creams
Can a custard cream be my only post-gym snack?
It can be the sweet snack you choose, but do not assume it supplies much protein: Tesco and Sainsbury’s list 0.7 g per biscuit, and Asda lists 0.6 g. If you are planning food around a short interval before another demanding session, consider the rest of what you will eat rather than judging that plan by the biscuit alone.
Is an individual custard-cream pack a single bar?
Not in the Crawford’s assorted mini-pack format described by Thompsons Food Service: each packet contains three biscuits. Check the biscuit count as well as the packet’s total nutrition when you want a defined portion.
How do I compare a custard cream with a protein bar?
Compare the nutrition for the amount you would eat, using the same basis for each product. A custard cream and a protein bar are different foods; a protein-related name alone does not tell you the protein, sugars or saturates in the portion.
Do England’s school food standards apply to my personal snack?
No: GOV.UK describes those standards as applying to food served in maintained schools and academies in England, not to a personal purchase after the gym. If you are supplying food at a school, check the applicable requirements for that setting and service.
