A leavening agent is an organism or substance used in baked goods that causes them to rise. When added to moisture, the leavening agent reacts to produce carbon dioxide that becomes trapped as bubbles within the dough.

Commonly used leavening agents include:

• baker's yeast
• sourdough
• yogourt
• baking powder
• steam
• air
