What happens if you put 3 eggs instead of 2 in a cookie recipe?

Putting 3 eggs instead of 2 in a cookie recipe will likely result in denser, chewier cookies. Here's why:

* More moisture: Eggs contribute moisture to cookies. Adding an extra egg will increase the moisture content.

* More protein: Eggs also contain protein, which adds structure to the dough. More protein means more structure and a denser cookie.

* Impact on texture: The extra moisture and protein will likely make the cookies less spread and more chewy. They may also be slightly more cake-like in texture.

* Potential for overmixing: Adding more eggs can make the dough more susceptible to overmixing, which can lead to tough cookies. Be sure to mix the dough only until just combined.

Whether this is a good or bad thing depends on your preference:

* If you like chewy cookies: Adding an extra egg could be a positive change.

* If you prefer crisp cookies: Adding an extra egg might not be ideal as it could make the cookies too chewy.

It's always best to experiment and see what you prefer! You could try making a batch with 2 eggs and another batch with 3 eggs to compare the results. You can also adjust other ingredients, such as flour or sugar, to compensate for the extra moisture from the third egg.
