Question about using protein powder in recipes

[TracieCat 8]

I made some no bake homemade Protein bars today using basically just uncooked regular oatmeal, Protein powder, a homemade non dairy milk substitute (my Dr. frowns upon milk) and some cinnamon. All patted down into a big glass baking pan and it is now setting up in the fridge.

Here is my question... It is my understanding that if you PREMIX Protein shakes from powder and try to store them, the Protein in them starts to break down and becomes essentially useless as a supplement. So what happens to the protein when you use it in a recipe, either in a no bake form like I did, or when it is used in a baked form?

Will that protein still break down and become useless to me in recipes? I tried doing a search for this info online and could find nothing that fit my question, only that yes indeed, you should NOT premix Protein Powder with liquid and store it for longer than a day, even if refrigerated.

I sometimes am having problems getting all of my protein in and I think having the homemade bars around to use as a Meal Replacement will really help me if they can indeed be used. Am anxious to try some other flavor combos, maybe sometimes add some Peanut Butter powder or slivered almonds, flaxseed, etc.

Thanks to anyone that has some info concerning this question. I appreciate it.
