Prioritize substitutions that protect gluten development and fermentation performance. Bread dough is less forgiving than quick bakes. Structure and fermentation can collapse with poor substitutions.
Yes. Start with Blended Granulated Sugar at Blend 1 cup granulated sugar + 1 tbsp cornstarch until powdery, then adjust liquid or bake time in small steps after a test batch.
Use Blend 1 cup granulated sugar + 1 tbsp cornstarch until powdery
Homemade powdered sugar works perfectly. Blend for 30-60 seconds.
View full adjustment notes →Powdered sugar carries roughly 3% cornstarch, and that starch is the problem in an enriched yeasted dough like cinnamon rolls or brioche — it absorbs hydration that should be feeding gluten development, leaving a slack, leaden crumb that proofs slowly and tears instead of pulling. The fine grind also dissolves instantly into the liquids, so it can't shield the yeast from osmotic stress the way granulated does in high-sugar sweet doughs. For a glaze on babka or sticky buns it's fine; in the dough itself, blend your own from granulated and use 1 cup + 1 tbsp cornstarch per cup called for, accepting some crumb softness.
