1 tablespoon baking powder
1 teaspoon baking soda
1 tablespoon flour

This "egg" recipe should be added last to any of your baking.
Mix the dry ingredients first, then add the water. Make sure there are no clumps and then add it to whatever you're baking.
This is SOOOOOOOOO simple and easy. It works really well, not to mention it's really cheap!!!
