Can you substitute 3 eggs for teaspoons mayo in carrot cake?

You should not substitute 3 eggs for teaspoons of mayonnaise in carrot cake. Eggs and mayonnaise serve different functions in baking, and changing the proportions of either can significantly alter the texture and taste of the cake. Eggs provide structure, richness, and moisture to the cake, while mayonnaise adds moisture and fat. Without the eggs, the carrot cake may become dense and crumbly, and the texture would be significantly different from a traditional carrot cake.

It is not advisable to substitute ingredients in a recipe without proper knowledge and testing, as it can drastically change the outcome of the dish.
