youtube it. Alot of recipes.
Almost all of them call for oatmeal though. Not sure how you would get around not putting it in?
You need some kind of base to create the actual bar shape and solidness.
Oatmeal, protein, natural peanut butter, slivered almonds, either dried cranberries or raisins and milk. Set in the fridge for 30 - to an hour or even over night and you should get good results.
I dont like oatmeal unless it's made like this haha.
