Prep Time 1 minute

Equipment

  • Blender, food processor, or spice grinder
  • Fine-mesh sieve (optional, for extra smoothness)

Ingredients
  

  • 1 cup granulated sugar (Pure cane sugar recommended—Florida Crystals is my go-to for a natural, less processed option)
  • 1 tbsp cornstarch (optional but helps prevent clumping)

Instructions
 

  • Add sugar to blender
    Pour the granulated sugar into your high-speed blender or food processor. If you’re using cornstarch, add it now.
    Blend until fluffy
    Blend on high for 30–60 seconds, or until the sugar transforms into a fine, fluffy powder. Be careful not to open the lid too quickly—there’ll be a cloud of sugar dust!
    Check the texture
    Feel a bit between your fingers. If it’s still gritty, blend a little longer.
    Optional: Sift for smoothness
    For ultra-fine powdered sugar (ideal for icing or dusting), pass it through a fine sieve.
    Store it right
    Keep in an airtight container at room temperature for up to several months. Add a little more cornstarch if storing long-term to keep it from clumping.
  • This recipe works with any granulated sugar, including white, cane, coconut sugar, or even maple sugar.
    Skip the cornstarch if you’re using it immediately in recipes like frosting or glazes.
    Great for last-minute baking emergencies—or simply for more control over your ingredients!
