Denny's does use eggs in their pancake batter to make their pancakes.
If you're allergic to eggs then you can ask Denny's to make the pancakes without eggs and they will do so.
IHOP also uses eggs in their pancake batter as well.
IHOP and Denny's eggs are real eggs but IHOP and Denny's uses powdered eggs to make their eggs with.
Denny's as well as I Hop use powdered eggs.
I used to work for both Denny's and I Hop and we made eggs using powdered eggs.
Although we did have real eggs for those people who wanted real eggs.
Denny's does use fake eggs well at least powdered eggs and they are real eggs but in powder form.
The Denny's Eggs are powdered eggs that they buy in canisters however if you do want real non powdered eggs at Denny's they will almost always cook real eggs for you.
Powdered eggs are not bad for you since powdered eggs are made from real eggs.
Powdered eggs are just as healthy as regular eggs are because the powdered eggs are just the eggs turned into a powder form that makes them last a long time.
Powdered eggs are easy to store and last a long time on the shelf or in your pantry.
Keeping powdered eggs is a good idea for possible natural disasters when you need emergency food.
I get powdered eggs from a food pantry and I have several of them and eat them once in awhile and if someone else needs some to eat I give them to them as well.
Powdered eggs contain the same health benefits as regular eggs although in my opinion fresh eggs that are not in the powdered form are much better tasting.
