Powdered milk can be added to most recipes to add more nutrition...

You might look into PB2. It's powdered peanut butter, can add nice flavor and some protein without being sticky in your recipe, and it's low-fat compared to regular PB. Probably not enough protein on its own, but maybe a nice ingredient for your bars.

Just some info re: Protein Powder. My DH was using it in his morning VitaMix drinks. He had some lab tests done & one of the tests came back with a concern. When he told the Dr. he was using Protein Powder, she told him to stop. He did & redid the test which came back in normal ranges. She told us you can get the same amount of protein, vitamins etc. in a regular glass of milk. Hope this helps. Just because it says Protein Powder, does not make it the best thing for you.

I agree with powdered milk as the simplest cheapest, but all that work seems complicated for what is basically a candy bar?
Why not drink a cup of milk or eat a hard boiled egg before you sit down with your coffee? Cut out the middle man so to speak

I use unflavored whey protein when I make smoothies. I buy it at a local health food store. (Not one of those chains)

you can make your own whey protein with yogurt, just strain all the liquids out, and the liquids are whey. I make mine with a cheese cloth. the yogurt tastes really good afterwards too.

I use ....ISOPURE... can get flavored or plain... never had a taste i could tell.. and i do use it often.. in my low carb cooking get it on amazon but it lasts a long time...

You can purchase protein powder at Walmart in the drug store area & Meringue Power there where they have the Wilton cake supplies or any craft store in the same area . Two Tablespoons of Meringue Powder equals 1 egg white . It is also used to make Buttercream icing . Haven't heard anything negative about egg whites yet .

I use whey protein powder. I chose it over soy only because at the time I had mold in my house and it helps kill the mold that could be in my system. I talked to my specialist and he said either soy or whey were good. If you have a health food check with them. I buy mine at the military exchange, so much cheaper than the health food store. I'd just research them. I try to only buy vanilla because then I can change the flavor to anything that I want. They didn't have it this time so I got cookies n cream, close enough to vanilla
