and you only have one. It's for a cake and I only have one egg, what can I substitute for the 2nd egg?What if your recipe calls for two eggs......?
4 tablespoons of mayonaise- and makes it softer and moister. I use mayo only instead off the eggs. It turns out much better. Plus, instead of water, I use milk.What if your recipe calls for two eggs......?
yes what they said or you can just leave it out...i have done that before
you don't need to substitute for a missing egg.. you can just use the one.
You can substitute 3 tablespoons of mayonnaise for the missing egg.
You can use just one egg and it will turn out more like a Brownie...or here are a few choices:








2 tbsp corn starch = 1 egg


2 tbsp arrowroot flour = 1 egg


2 tbsp potato starch = 1 egg


1 heaping tbsp soy powder + 2 tbsp water = 1 egg


1 tbsp soy milk powder + 1 tbsp cornstarch + 2 tbsp water = 1 egg.


1 banana = 1 egg in cakes.
yes it would be ok you can substitute things when it comes to cooking its your recipe
