Powdered sugar is a must-have for many baking recipes. Luckily, it’s really easy to make at home.
In a food processor or blender, combine 12 oz of white sugar and 2 tablespoons of corn starch. Place the lid on securely and pulse until the mixture becomes powder-like in consistency. If you’re using a blender, carefully wipe down the sides with every five pulses to keep the blade from sticking.
Exact measurements aren’t necessary – eyeball it. You can even use your fingers if they fit through the mouth of your container well enough!
Store leftover powdered sugar in an airtight container free from moisture and heat for up to a year before discarding or reusing as needed according to recipe instructions.
Note: you can use an electric mixer set to a low speed instead of a food processor or blender, but it will take much longer because there won’t be enough air flow to properly and fully incorporate the sugar into a powder. You’ll also need to keep extra mixing time in mind as well because you won’t have as much control over how fine the texture of your powdered sugar becomes.
So this is how you can make powdered sugar.
