⭐ Margarine (Best Dairy-Free Option)
1:1 by volume (e.g., 1/4 cup margarine per 1/4 cup butter)Margarine is formulated to have a fat and water content very similar to butter, which is critical in yeast bread for proper gluten lubrication and gas retention during fermentation. The solid fat helps create a tender crumb and contributes to flavor.
For best results, use stick margarine rather than tub margarine, as the latter often contains more water. Chill margarine before mixing to maintain dough consistency.
The final bread will have a slightly different flavor profile, often less rich and buttery, but texture and rise will be nearly identical to using butter.
