Ingredients Method Notes

Ingredients
  

  • 1 cup granulated sugar
  • 1 tbsp cornstarch (optional for anti-caking)

Method
 

  1. Set Up Your Blender or Food Processor: Use a high-speed blender or food processor. Ensure it's clean and dry for the best results.
  2. Combine Ingredients: Add the granulated sugar to the blender or food processor. If you’re using cornstarch, add it now. Cornstarch helps prevent clumping and creates a silky texture, especially if you’re storing the powdered sugar.
  3. Blend Until Fine: Blend on high speed for 1-2 minutes or until the sugar has transformed into a fine, powdery consistency. Pause occasionally to scrape down the sides to ensure even blending.
  4. Check Consistency: To test, rub a small amount of the sugar between your fingers. It should feel light and powdery. If it feels grainy, blend for an additional 30 seconds.
  5. Store Properly: Transfer your powdered sugar to an airtight container. Store in a cool, dry place for up to a month. Label the container for convenience.

Notes

Tips for Success:

  • Choose the Right Sugar: Regular granulated sugar works best. Avoid coarse sugars as they may not blend finely.
  • High-Speed Blender: For the smoothest texture, a high-speed blender is ideal, though a food processor works in a pinch.
  • Storage Tip: Always use an airtight container to prevent moisture from clumping the powdered sugar.
  • Flavor Boost: Add a small amount of vanilla powder or cinnamon for a unique twist.
