Protein bar recipe and temperature so not to denature protein powder

[Xray123]

I want to make my own protein bars.

If I use whey or casein powder, will it be denatured in the oven? What is the recommend temperature?

Any one know any good recipes?

I will be using protein powder, crushed mixed nuts, grounds oats, olive oil and milk.

I am not concerned about taste, nutrition is much more important.
