Why does Jiffy cornmeal mix fall flat?

Jiffy cornmeal mix may fall flat due to insufficient leavening agents, which are essential for creating rise and texture in baked goods. If the mix is not combined properly or if the baking powder is old or ineffective, it can lead to dense, flat results. Additionally, factors like incorrect oven temperature or inadequate mixing can also contribute to the mix not rising as intended. Proper measurement and attention to baking instructions are crucial for optimal results.
