I’ve been asked many time, and maybe you are wondering too.

Can eggs be replaced with mayonnaise when baking?

Yes! Eggs can be swapped for mayonnaise when baking everything from cake to bread.

For each egg your recipe calls for, add three heaping teaspoons of mayonnaise.

Mayonnaise works as an egg substitute in baking because it contains egg along with oil. But the added oil means that adjustments need to be made in your recipes other fats.

Most cakes, cookies, and baked goods call for butter. Therefore, if your recipe is replacing three eggs with mayo, then you will reduce your butter in half.

This will account for the added fat in the mayonnaise.

Keep in mind that this refers to regular fat mayo. Do not use flavored mayo when replacing eggs. Regular mayonnaise is the way to go.

Why Mayo Works as an Egg Alternative

Eggs are added to baked desserts to provide richness, flavor, structure as well as acting as a leavening agent.

Because mayonnaise has eggs in it, structure, flavor, and leavening are provided. But keep in mind that mayo only has egg whites in it.

As stated above, mayo has more fat than eggs which must be adjusted in your recipe by reducing other fats.

With that said, mayo will provide your recipe with the flavor, structure and leavening needed.

Cons of Using Mayonnaise Instead of Eggs
