Each recipe is different, but no-cholesterol recipes DO exist.
No. The eggs don't make cakes rise. It is the baking powder in the cake flour.
A box cake calling for 3 egg whites would not rise properly without the egg whites. Applesauce is not a suitable substitute for egg whites. Possible solutions would be to borrow eggs from a neighbor, or prepare a different dessert using available ingredients.
I'm going to answer this assuming you mean regular chicken eggs. The four types of eggs used in baking are whole eggs, egg yolks, egg whites, and meringue. Meringue is simply egg whites which have been beaten until they are light and fluffy, and hold a stiff peak. This is commonly done with many cake recipes to increase the volume and lightness of the cake.
No. Egg yolks are required.
You can make a whole wheat cake with unrefined sweeteners; you can add fruit or veggies, and eggs.
There's allot if cholesterol in the yolk.
Fresh eggs are always better for taste and quality, but - as long as the eggs haven't gone bad - they will still do just fine.
no, but the cake might the eggs won't go bad because there cooked into the cake like when you make eggs they won't go bad they'll only get cold & if you leave them out long enough they'll get moldy.
no that would be gross
Eggs keep your cake together without eggs your cake would fall apart.
Most cake recipes have the same basic ingredients; dry ingredients flour, sugar, baking powder, a pinch of salt; and wet ingredients water or milk, eggs, and often vanilla extract. These ingredients will make a yellow cake; for a white cake, egg whites are used instead of whole eggs; for chocolate cake, chocolate is added in solid, powder, or liquid form. There are thousands of variations of other ingredients such as fruits, nuts, honey or molasses, alcoholic beverages, candies, etc. See the links below for some basic cake recipes.
Flan cakes of all flavors are very popular, and many of them call use boxed cake mixes, which almost always require 3 eggs. In fact, most 2-layer cakes, whether made from a mix or made from scratch, call for 3 eggs.
