Granulated Sugars

Powdered Sugars in Muffins sweetens, tenderizes the crumb, and promotes a golden crust. A stand-in should match its moisture-holding nature to avoid dryness.
Blend in blender until powdery; add 1 tsp cornstarch
Use 1/2 cup molasses in glazes; strong flavor, dark color, only for flavored frostings
Molasses at 0.5 cup per cup brings 22% water and 4.5 pH acidity; increase baking soda by 1/4 teaspoon to balance and reduce milk by 2 tablespoons. The muffins gain deep caramel notes and a mahogany dome but won't rise as high — the acidic batter sets faster. Bake at 375°F for 20 minutes instead of 400°F to avoid burning.
Liquid sweetener; use 3/4 cup honey per cup powdered sugar, reduce other liquids in the recipe
Honey at 1 cup per 1.25 cups powdered sugar adds 17% water; reduce other liquid by 3 tablespoons and lower the oven to 375°F since honey browns faster. The tender crumb holds moisture an extra day and the dome browns darker than with powdered sugar. Paper cup liners release cleanly when the muffins cool 5 minutes in the tin before removal.
Blend fine in food processor 3 min; slightly coarser texture, good for dusting cookies
Blend fine with 1 tsp cornstarch; maple flavor, use in glazes and frostings
Use 3/4 cup syrup for glazes; won't work for dusting, reduces liquid elsewhere in recipe
Thick syrup for wet glazes only; adjust liquid in recipe, no dusting or stiff frostings
Use for fruit glazes on desserts; adds flavor and moisture, not a dry dusting sugar
Use powdered sugar-free sweetener for low-carb; results vary by brand, check package
Flavored thick syrup for glazes and drizzles; adds fruity note, not for stiff frostings
Moist with molasses flavor; pack firmly and use 1 cup per cup powdered, adds color and caramel notes
Powdered sugar in muffins works by coating flour particles before liquid hits them, which limits gluten development and protects the tender crumb during the 18-22 minute bake at 400°F. Whisk the sifted sugar into dry ingredients first, then fold wet into dry in under 12 strokes — stop while streaks remain, since overmixing is what kills dome height.
Unlike cake, which is beaten vigorously for 2-3 minutes to emulsify fat and sugar into an aerated batter, muffin batter is deliberately lumpy and barely combined so leaveners can drive a tall, cracked dome in paper cup liners. And unlike scones, where powdered sugar sits on top as a finish, in muffins it's fully incorporated to sweeten from within and retain moisture for a 2-day shelf life.
Scoop with a #16 disher into a 12-cup tin filled to the brim, optionally topped with a streusel, and rotate the tin at 10 minutes for even browning on the tops.
