How to replace eggs in baking recipes

serves:

Eggs provide proteins and help any recipe to rise. However, you may encounter someone that is allergic to eggs or, even worse, is vegan and will not eat eggs. In case you want to serve him a special treat for his birthday, you might want to replace the eggs in your baking. 

Simply replace one egg by 3 tablespoons of apple sauce and one teaspoon of baking powder. This will mimic the qualities of a whole egg in baking recipes.
