Granulated Sugars
6.7Blend in blender until powdery; add 1 tsp cornstarch
Powdered Sugars in the custard soak for French Toast helps caramelize the exterior to golden brown. The stand-in should dissolve evenly in the egg mixture.
Blend in blender until powdery; add 1 tsp cornstarch
Blend fine in food processor 3 min; slightly coarser texture, good for dusting cookies
Flavored thick syrup for glazes and drizzles; adds fruity note, not for stiff frostings
Liquid sweetener; use 3/4 cup honey per cup powdered sugar, reduce other liquids in the recipe
Honey dissolves instantly in the warm custard base like powdered sugar but browns 30°F lower, so drop the griddle to 325°F or the crust scorches before the bread absorbs fully. Use 1 cup honey per 1.25 cups powdered sugar and reduce milk by 2 tablespoons. Flip once when the first side is mahogany for that signature butter-and-honey flavor.
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 1/2 cup molasses in glazes; strong flavor, dark color, only for flavored 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
Moist with molasses flavor; pack firmly and use 1 cup per cup powdered, adds color and caramel notes
Powdered sugar dissolves into the egg-milk custard in under 10 seconds because of its tiny crystal size, meaning you can whisk 2 tablespoons into 3 eggs and 3/4 cup milk without the graininess you get from granulated. That instant solubility matters: as the bread absorbs the custard, the dissolved sugar travels into the interior, where it caramelizes on contact with the 350°F griddle for a deeper brown exterior.
Unlike pancakes, which rely on the sugar browning in a thin batter on a bare griddle, french-toast's sugar is locked inside soaked bread and needs 2-3 minutes per side in 1 tablespoon butter to develop that crust without scorching. Dip slices of day-old brioche for 15-20 seconds per side — longer and the center turns mushy — then flip once when the first side is mahogany.
Vanilla and a pinch of salt round the flavor; finish with a drizzle of syrup rather than more sugar on top.
Don't soak bread longer than 20 seconds per side in the custard; over-saturated slices turn mushy in the center and can't absorb the vanilla properly during the 3-minute griddle sear.
Use day-old brioche, not fresh — fresh bread collapses in the egg soak and loses its tender-bread structure under butter.
Whisk the custard until no egg strands remain; streaks show up as rubbery patches on the browned surface after the flip.
Pre-heat the griddle to 350°F and test with a butter drop — if it sizzles loudly, it's too hot and will scorch the sugar before the bread interior warms through.
Skip piling syrup on top during cooking; it burns to a bitter crust. Finish syrup at the table after a final dusting of powdered sugar.
