Muffins are fun to make due to their versatility and delicious flavors. Adding vanilla or walnuts can elevate this treat, but mayonnaise is the secret ingredient you need to try.

While it might seem like an odd choice, it makes sense because mayo is usually made up of oil and eggs, making it a great substitute for ingredients commonly used in muffins.

Adding mayo can infuse the muffin batter with added fat and moisture, which can result in tender cakes. It will also balance out overly sweet flavors with its tartness and tang.

You can swap out any butter or oil for a healthy portion of mayo in recipes that don’t take their structure from butter. Three tablespoons of mayo can also replace eggs.

Finally, you can add mayo in addition to your eggs and fat to help enhance the mixture. Make sure you add a tablespoon at a time at first for the best results.
