Now read this. Where many beginners go wrong in baking is trying to substitute one ingredient for another. I'll just put in whole-wheat flour instead of white flour. Then they wonder why they have baked a brick. Adobe would be easier to eat.
Whole wheat is heavier.
One of the most frequent baking mistakes is the use of breakfast spread instead of butter or margarine. This is a guaranteed way to wind up throwing your results in the trash can. If the first ingredient on the label is water, don't use it for baking. Stick margarine that is at least 80 percent fat can be substituted for butter. For best results, use butter if the recipe calls for butter.
