ELI5: Do raw ingredients for baked goods share the same nutritional value as the final product?

It seems too "easy" to just add up the total calories, fat, etc from each of the individual ingredients due to any chemical reactions that happen during the actual baking process from the combined ingredients in a heated environment. Examples could be any baked good like bread, cake, etc. I know when cooking it seems like it's fairly straightforward (minus any burned off grease/fat left in the pan/bowl/etc), but baking seems like it'd be different.  


Basically, I wonder if I could just eat all of the ingredients (whether that can cause other health issues aside) and get the same level of nutrition that'd be labeled on the recipe/box.

No. Part of the reason for cooking foods is that the cooking process makes some of the components of the food more available for absorption and use. Its not adding anything, just causing some changes. Starches can become sugars. The sugar is easier for your body to use, so you get more nutrition/calories from it. If you ate the pre-cooked high starch ingredient you wouldn't be able to break down and absorb as much. 

Its similar with cooking meat. The cooking process alters the meat breaking down some of the tougher parts making it easier for your body to break down and digest.
