To replace 1 egg -
You have just one alternative, buy a packet of egg substitute from the supermarket for your baking.
From BBC website: Tony Bishop Weston from the Vegan Society recommends a number of ingredients that can be used as egg replacements. He says, "Cocoa butter, xantham gum, agar agar, arrowroot, locust bean gum, carob, vegetarian gelatine, vegan egg replacer, soya flour, banana, potato flour or chocolate all work well".
I use soya flour - about the same volume as egg.
Try ENER-G EGG REPLACER (see related link below). Ener-G is economical, easy to use, gluten-free, and certified Kosher. Even if you're not vegan, using egg replacer while baking will help lower your cholesterol intake and, as one box is the equivalent of 100 eggs, its a good investment as well.
It's probably easiest to look at vegan recipes; vegan's don't eat dairy or eggs so they have developed recipes that avoid them. Try the BBC vegan baking webpage: http://www.bbc.co.uk/food/vegetarian_and_vegan/veganbaking.shtml as a starting off point.
Tofu scramble is a good substitution for scrambled eggs. Tofu.
It might be that you attempted to make vegan cupcakes from a regular mix or recipe calling for eggs. The eggs provide leavening (rise) and structure to the batter as it bakes. To make vegan cupcakes you would need some other ingredient to replace the eggs. Some vegan recipes use additional oil to replace the fat in the egg yolks, along with cider vinegar and both baking powder and baking soda to provide leavening. See link below for some examples.
Most baking recipes equire eggs as an ingredient because they act like a glue and hold the flour/sugar/etc. together. Vegan recipes have no eggs, and will often call for suitable egg substitutes such as ground flax seed and water.
One egg can be substituted for 1/4 cup of applesauce. For three eggs, one would use 3/4 cup of applesauce. Applesauce is a common replacement in cake and other recipes for eggs.
it holds the cake or any other thing that you are baking together
There is as wide a variety of vegan desserts as non-vegan desserts. I do a fair amount of vegan baking and there are great vegan baking books. Essentially you have to replace the milk, eggs and butter with vegan counterparts which is not hard to do with all the great products available these days. If you don't already have favorite recipes try some that are already created for (and tested for) vegans. The book "The Joy of Vegan Baking" is great. We use Earth Balance butter substitute at my house, EnerG egg replacer and different non dairy milks (soy, almond, coconut) depending on what dessert it is. Good luck from Bunni Dot Com
A vegan vegetarian, or vegan for short, does not eat any animal product. This includes meat, dairy, eggs, fish, honey, or any foods that contain those products in their recipes.
Because in a lot of recipes you have to beat your eggs. Especially when you are baking something you don't use them as much when you are cooking.
Eggs and honey are not vegan but are vegetarian. Vegetarian- not mean. Vegan- not from an animal. Fish is not vegan.
For breads the basic would be flour, eggs, yeast, Baking powder,baking soda. and shortning.. (fat). most cake recipes use the same minus the yeast.
In some recipes you might, but you will definitely get a different taste and consistency out of the cookies. It is always best just to stick to the ingredients that the recipe calls for.
