First, you need a small, powerful blender, like a spice grinder, Nutri bullet, Vitamix, or food processor. I had the best success in a blender. You might have to try a few different appliances to see what works best.
Add in the sugar and cornflour/cornstarch. The cornflour is important as it keeps the sugar dry.
Blend it all together until fine, around 4-5 minutes. Stop, and stir with a spatula to make sure it gets mixed all around so that it is all blended.
After a few minutes, run it through your fingers; if it feels gritty, then keep blending. You might still feel a little texture at the end, but that’s ok. If you can’t seem to get it really fine, you might need to try a smaller, stronger blender.
Store your Homemade Powdered sugar in an airtight container; it will keep indefinitely.

If you use a Bullet or a blender that doesn't have a good powerful motor always pulse with small amounts, otherwise you can burn up the motor .

Don't try with just an average blender. Still gritty after 10 minutes. Good to know though.
