โญ Baking Powder (Best Nut-Free Option)
1 teaspoon per cup of flourBaking powder is a chemical leavening agent that releases carbon dioxide gas when moistened and heated, causing the batter to rise quickly. This mimics the leavening effect yeast would provide but without fermentation or flavor changes.
For best results, mix baking powder thoroughly into the dry ingredients to ensure even distribution. Avoid overmixing the batter after adding wet ingredients to prevent excessive gluten development and toughness.
Compared to yeast, baking powder yields a lighter, more tender brownie with a consistent crumb and no fermentation flavor, which aligns better with traditional brownie texture and taste.
