What happens if you use only one egg for a store bought cake mix that requires three eggs?

If you attempt to use only one egg in a store-bought cake mix that requires three eggs, the final cake will likely turn out dry and crumbly. This is because eggs contribute to the structure and texture of a cake, providing moisture and binding ingredients together. Without enough eggs, the batter will not have the necessary structure to rise and form a cohesive cake.

To achieve the best results, it's important to follow the recipe and use the recommended number of eggs. Replacing all three eggs with just one egg can significantly compromise the outcome of your cake.

If you're experimenting with variations or substitutions in baking, it's a good idea to start with small adjustments and carefully observe the results. Adding too little or too much of a particular ingredient can lead to unintended consequences in terms of texture, taste, and appearance.
