As long as you’ve got a bag of plain white sugar in the pantry, you’ll never run out of icing sugar again – and you’ll cut down on packaging too. The Thermomix sounds like a jet engine while it blitzes, but it’s done in under a minute.

This recipe is part of my Thermomix pantry staples series, where I share quick and simple ways to save money and time by making everyday staples in the Thermomix, such as sweetened condensed milk and self-raising flour.

Icing Sugar Tips

Types of sugar: Use regular white sugar (any supermarket brand works perfectly). I don’t recommend brown sugar as the molasses makes it sticky and more likely to clump. You can mill raw sugar or coconut sugar, but the texture may be coarser than regular white sugar.

How to avoid a sugar dust cloud: After milling the sugar, let it settle for a few seconds before slowly opening the lid.

Grainy texture: To avoid a gritty texture, don’t mill more than 250g of white sugar at a time, and mill for at least 50 seconds on speed 10.

Frequently Asked Questions

No, cornflour is sometimes added to store-bought icing sugar to prevent it from clumping. See above storage tips and sieve the icing sugar before use for the best results.

If the texture of your icing sugar is not to your liking, just mill again in 30 second increments.

For best results, mill no more than 250g at a time. It’s quick to repeat if you need a larger amount.

Icing sugar tips: Use regular white sugar (any supermarket brand works perfectly). Avoid brown sugar, as it’s sticky and tends to clump. Raw or coconut sugar can work but may be coarser. For best results, blitz no more than 250g at a time. After milling the sugar, let it settle for a few seconds before slowly opening the lid – this prevents a dust cloud.
