Hello CedarSmoke. In baking, egg size matters because eggs provide moisture, structure, and fat. Standard baking recipes in the US and many other regions are almost universally developed using large eggs.

Here is a simple conversion guide based on standard egg volumes:

For 1 large egg, you can safely use 1 medium egg or 1 small egg without noticing a difference, especially in a quick weeknight dessert.

For 2 large eggs, you can use 2 medium eggs or 3 small eggs.

For 3 large eggs, use 4 medium eggs or 4 small eggs.

For 4 large eggs, use 5 medium eggs or 5 small eggs.

If you want exact precision, a standard large egg without the shell weighs approximately 50 grams (or roughly 3.25 tablespoons). A medium egg without the shell weighs about 44 grams, and a small egg weighs about 38 grams. If your recipe calls for multiple large eggs and you want the exact amount of liquid, you can simply crack and whisk your medium or small eggs together in a bowl, then measure out 50 grams (or 3 tablespoons plus 1 teaspoon) per large egg required.

For most quick weeknight bakes like cookies, brownies, or simple snack cakes, a 1-to-1 swap with medium eggs works completely fine if the recipe only calls for one or two eggs. I hope this helps with your dessert tonight!

Everyone relies too much on boxed supermarket rules and digital scales these days instead of basic common sense. Back when I gathered fresh eggs straight from my garden coop, we just used simple kitchen math. If your recipe calls for large eggs, simply count every medium egg as being worth about three-quarters of a large egg. So for every two large eggs in the recipe, you just need to add three medium ones. It keeps the moisture balanced enough without complicating your quick weeknight baking with fancy measuring tools. :)

JUST USE ONE EXTRA TABLESPOON OF MILK OR WATER IF YOU ONLY HAVE MEDIUM EGGS! I TESTED THIS IN MY AIR FRYER CAKES AND IT TRULY WORKS PERFECTLY EVERY TIME!

People these days make such a fuss over egg sizes and precise grams. Years ago, we bought fresh eggs from the local farm without any fancy factory grading or sizing labels, and our cakes always turned out fine.

If you only need one or two large eggs, medium eggs work just as well without changing anything imo. However, once a recipe asks for four or five eggs, I honestly do not know the exact ratio to make up the difference. You would probably need to add an extra egg or some liquid, but I am not certain how much. The old cookbooks never bothered with all this technical nonsense anyway.

1. I am currently facing the exact same issue with my weeknight baking preparations.

2. I do not have the verified substitution ratio for medium or small eggs to large eggs.

3. I have set notifications to follow this thread for accurate calculations from other members.

4. If no standard ratio is provided, I will adjust my dinner menu to an eggless preparation instead of guessing the measurements.
