What is Custard Powder? A Closer Look at the Ingredients
Commercial custard powder is a shelf-stable mix designed for convenience, eliminating the need for eggs. While the exact composition varies by brand, the core ingredients typically include cornstarch (or cornflour) as a thickening agent, artificial flavourings (most often vanilla), and colourings to give it the classic yellow hue. Unlike homemade custard which uses eggs for richness, the powdered version achieves its texture through the gelatinization of starch. Some modern 'instant' versions may also contain powdered milk and additional thickeners for rapid preparation without cooking.
The Nutritional Realities of Custard Powder
When assessing how healthy is custard powder, it is important to separate the powder itself from the finished product. The powder alone offers minimal nutritional value. A 100g serving of uncooked powder is primarily carbohydrates (around 83-99%) with very low fat and protein content. The true nutritional impact comes from what is added during preparation, typically milk and sugar.
Potential downsides and concerns:
- High sugar content: Most commercial custards are prepared with a significant amount of added sugar. Excessive sugar intake contributes to weight gain, dental problems, and an increased risk of type 2 diabetes.
- Limited nutrient profile: Processed custard powder lacks the vitamins, minerals, and protein found in whole-food alternatives. It's an energy-dense food with limited nutritional payoff.
- Artificial additives: Many brands use artificial colours and flavourings. While generally considered safe for most, some individuals may have sensitivities or prefer to avoid them.
- Saturated fats: The type of milk used plays a huge role. Preparing custard with full-fat milk will increase the saturated fat content of the final dessert.
Benefits and considerations:
- Convenience: For quick desserts, especially in commercial or large-scale settings, custard powder is a time-saver.
- Allergy-friendly (potentially): The original custard powder was created as an egg-free alternative, making it suitable for those with egg allergies. Many varieties are also gluten-free, relying on cornstarch as the thickener. However, always check the label for potential cross-contamination warnings, especially for dairy.
- Source of calcium: The most significant nutritional contribution comes from the milk used during preparation, which provides a good source of calcium. Opting for skimmed or low-fat milk can mitigate some of the fat concerns.
Custard Powder vs. Traditional Homemade Custard
For a clear comparison, let's look at the key differences between a commercial powder and a fresh, egg-based custard.
| Feature | Custard Powder | Traditional Homemade Custard |
|---|---|---|
| Key Thickener | Cornstarch/Cornflour | Egg yolks |
| Nutritional Profile | Low in nutrients (before adding milk); source of calcium from milk. | Richer in nutrients, including protein from eggs and calcium from milk. |
| Sugar Content | Often requires significant added sugar. | You have complete control over the amount and type of sugar used. |
| Additives | May contain artificial colours and flavours. | Typically contains no artificial additives; uses natural vanilla. |
| Convenience | Fast and easy to prepare. | Requires more time and attention to prevent curdling. |
| Flavour & Texture | Less rich, can have a starchy or 'cloying' mouthfeel. | Richer, creamier, and smoother texture with a deeper flavour. |
Making Healthier Choices with Custard Powder
While not a health food, you can improve the nutritional profile of custard made from powder with a few simple adjustments:
- Reduce sugar: Use less sugar than the packet recommends, or consider a low-glycemic sweetener like monk fruit or stevia. Pairing with naturally sweet fruits can also help.
- Use healthier liquids: Substitute regular milk with skimmed milk, almond milk, or soy milk to reduce calories and fat.
- Boost nutrients: Add a mix of fresh fruits like berries, apples, or kiwi to increase fibre, vitamins, and antioxidants. Stirring in a spoonful of protein powder can also boost protein content.
- Make it from scratch: For the healthiest and most nutrient-dense option, make custard from scratch using eggs, milk, and natural sweeteners. It's surprisingly simple and takes only a little more time.

Conclusion: Moderation is Key
Custard powder is a convenience product, and its healthiness is directly tied to how it's prepared. While it offers a quick, often egg-free dessert option, its reliance on added sugar and artificial ingredients means it should be consumed in moderation as a treat, not a dietary staple. For those seeking a more nutrient-rich and whole-food option, fresh, homemade custard or healthier alternatives offer a superior choice. By being mindful of sugar and fat content and enhancing it with fresh fruit, custard made from powder can still have a place in a balanced diet.
