Well, you know what? Making your own powdered sugar at home with a Thermomix is almost a ritual for me. I admit that sometimes I panic in the middle of baking, telling myself “shoot, no powdered sugar to sprinkle”. And then hop, it’s the Thermomix that saves the day.
What I love about this method is the speed. In barely 20 seconds, you have this super fine sugar, ready to turn any dessert into a work of art. No need to buy those small industrial packets, already opened and sometimes a bit damp.
I also like it because it’s economical. A small bag of granulated sugar, which I customize according to my wishes, sometimes with a hint of powdered vanilla, and that’s it. I always have some on hand and it saves me time when I dive into my freestyle cakes.

How to prepare homemade powdered sugar with your Thermomix?

- Add the spoonful of corn starch, it’s my little personal tip, even though you can do without. Sometimes I forget, no problem, but it’s better with it.
- Blend for 20 seconds at speed 10. No more, otherwise you risk burning the sugar (yes, it can happen, don’t laugh, once I messed up).
- Stop, wait just two seconds for the powder to settle at the bottom, and stir lightly with a spatula to get an even mixture.
Essential utensils when making powdered sugar with Thermomix

I won’t hide that sometimes, when I’m in a hurry, I skip the starch, it still works. Well, it’s up to you, huh!
This sugar is ideal for sprinkling on your tarts, melting into a simple icing, or even discreetly sweetening a hot drink. A marvel!
Personally, I like to make a little extra and keep it in a jar: it avoids last-minute stress when a recipe calls you to the rescue.

Yes, the Thermomix is powerful enough to grind sugar cubes, but it’s better to start with granulated sugar to facilitate preparation and avoid prematurely wearing your blade.
