Ingredient Notes:

  • Sugar: You can use either granulated or caster sugar for this recipe.

Substitutions and Additions

  • Arrowroot Powder: A great alternative to cornstarch, especially if you’re looking for a grain-free or paleo-friendly option.

Recipe Tips

  • Keep It Fresh: Powdered sugar because sugar absorbs moisture, which can ruin it.
  • Work In Batches: If your spice grinder is small, just grind the sugar in smaller batches. Afterward, combine everything in a bowl and whisk or sift it to make it super smooth.
  • Use The Right Tools: Regular food processors usually can’t make the sugar fine enough, so they’re not the best tool for this job.
  • Get The Texture Right: If the sugar still feels rough or gritty, grind it for a little longer or try using a grinder designed for finer results.

Storing Tips

  • Storage: Powdered sugar can be stored in an airtight container at room temperature for up to 6 months.
  • Containers: I like to store my powdered sugar in glass containers with a tightly fitted lid to ensure it stays dry and fresh.

Serving Suggestions

I use powdered sugar most often in baked goods like these Crumbl Copycat Blue Monster Cookies, Copycat Crumbl Oreo Cookies, or these Cookie Monster Donuts!
