Homemade Vegan Powdered Sugar (Simple Vegan Blog) is a good recipe to master, as most powdered (icing) sugars on the market contain egg. Two that don’t are Suma (UK) and Wholesome! (US). But if you want to make your own, here is a recipe to do so. All you do is blend granulated vegan sugar with cornstarch, and then store in an airtight container.
