Can mayonnaise be used as an egg substitute in a brownie recipe?

No, mayonnaise is not a suitable substitute for eggs in a brownie recipe.

Here's why:

* Eggs provide structure and moisture: Eggs are crucial for the texture and consistency of brownies. They act as a binder, holding the ingredients together, and also contribute to the moistness of the final product. Mayonnaise lacks these qualities.

* Mayonnaise contains oil and vinegar: The oil and vinegar in mayonnaise would alter the texture and taste of the brownies. They would make the brownies oily and potentially acidic, ruining the desired chocolatey flavor.

* Mayonnaise lacks the emulsifying properties of eggs: Eggs act as an emulsifier, blending together the fat and water in the brownie batter. Mayonnaise cannot replicate this function.

Alternatives to eggs in brownies:

* Applesauce: Applesauce is a common egg substitute in baking. It adds moisture and some structure to the brownies.

* Mashed banana: Ripe bananas can also be used to replace eggs. They provide moisture and sweetness.

* Flaxseed meal: Mixed with water, flaxseed meal creates a gel-like substance that can bind the ingredients together.

* Commercial egg replacers: There are commercially available egg substitutes that can be used in baking.

Recommendation:

It's best to stick to using real eggs in your brownie recipe. If you're trying to avoid eggs for dietary reasons, choose one of the alternative substitutes mentioned above.
