Baking Powder (Best Option)
1/2 teaspoon per 1 cup of dry granola mixBaking powder is a chemical leavening agent that releases carbon dioxide when moistened and heated, creating lightness and a subtle rise. In granola, this can help achieve a slightly crispier texture without fermentation or off-flavors. Since granola is typically dry and baked at moderate temperatures, baking powder's mild leavening is sufficient to improve texture.
To use baking powder effectively, ensure it is evenly mixed into the dry ingredients before baking. Avoid excessive amounts to prevent a bitter taste. Baking powder works best in granola recipes that include some liquid or syrup to activate it.
Compared to yeast, baking powder does not require fermentation time and does not produce the distinctive yeasty aroma or flavor. The final granola will be crisp and lightly aerated rather than chewy or fermented.
