Mayonnaise, a creamy and tangy condiment that’s often used to dress up sandwiches and salads, may seem like an unusual ingredient to use in baking. However, mayo is a versatile kitchen staple that can work wonders in your favorite baked treats.

What Does Mayo Do in Baking?

Mayo is made of eggs, oil, vinegar, and seasonings, which are all common ingredients in baking. When you add mayo to your cake or bread batter, it can serve several purposes:

  1. Adds Moisture: Mayo is an emulsified mixture of oil and water, which means it can add moisture to your baked goods without making them greasy. The oil in mayo can also help to keep your cakes and breads moist for longer.
  2. Enhances Texture: The creamy texture of mayo can give your baked goods a tender and velvety crumb. It can also help to prevent your cakes and breads from becoming too dry or crumbly.
  3. Improves Flavor: The vinegar and seasonings in mayo can add a tangy and savory flavor to your baked goods. It can be especially delicious in chocolate cakes, where the acidity can enhance the richness of the chocolate.

Now that you know what mayo does in baking, you may be wondering how to use it in your favorite recipes. Here are some tips:

  1. Substitute Mayo for Oil or Butter: You can use mayo instead of oil or butter in your cake or bread recipes. Use a one-to-one ratio, and be sure to mix the mayo well with the other ingredients to ensure a smooth batter.
  2. Add Mayo to Boxed Cake Mixes: If you’re short on time, you can use mayo to improve the texture and flavor of boxed cake mixes. Just add a few tablespoons of mayo to the batter before baking.
  3. Make Mayo Frosting: Mayo can also be used to make a tangy and creamy frosting. Mix mayo, powdered sugar, and vanilla extract to make a simple and delicious frosting for your cakes and cupcakes.
