I'll show you how to make powdered sugar, aka confectioner's sugar, so you'll never run out when making any of my baking recipes!

  • 2 cups (16oz/450g) white sugar
  • 2 tablespoon cornflour (cornstarch)
  1. 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.
  2. Add in the sugar and cornflour/cornstarch. The cornflour is important as it keeps the sugar dry.
  3. 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 getting blended.
  4. After a few minutes run it through your fingers and 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.
  5. Store your Homemade Powdered sugar in an airtight container and it will keep indefinitely.
