Ingredients Method Notes

Ingredients
  

  • 1 cup Granulated Sugar Blend with 1 tablespoon cornstarch until silky for homemade powdered sugar
  • 1 cup Caster Sugar Use 1:1 ratio in baked goods where heat dissolves sugar
  • 1 cup Maple Sugar Use 1:1 for dusting and toppings; adds caramel flavor
  • 1 cup Powdered-Style Granulated Sugar Pulse 1 tablespoon cornstarch with granulated sugar; coarser than icing sugar
  • 1 cup Powdered Erythritol Use 1:1; suitable for low-sugar baking but has cooling aftertaste
  • Cornstarch & Granulated Sugar Blend Mix 4 parts sugar to 1 part cornstarch; less sweet, good for dusting
  • 1 cup Granulated Sugar with Cornstarch and Arrowroot Powder Blend 1 cup sugar, 1 tablespoon cornstarch, and 1 tablespoon arrowroot powder for best anti-caking

Method
 

  1. Select the substitute that best fits your use case—baking, frosting, dusting, or low-sugar needs.
  2. If making powdered versions, blend granulated sugar with starches for 60-90 seconds until silky smooth.
  3. Apply the substitute using recommended ratios, adjusting quantities for sweetness or texture as noted.
  4. For cold uses like frosting or glazes, prefer homemade powdered sugar or the DIY fine powder blend.
  5. Check the final texture and taste, adding a pinch of salt to powdered erythritol to reduce cooling effect if desired.

Notes

  • Homemade blends need a powerful blender for the finest texture.
  • Caster sugar works well in heat but is not suitable for cold frostings.
  • Cornstarch or arrowroot powder prevents clumping and stabilizes frostings.
