Gave this shot for the first time a couple of weeks ago (stole it from youtube) - wasn't the best idea given I'm deep in competition prep but managed to stretch out my consumption of all of them over a few days so the damage was somewhat lessened ! Going to do it on a regular basis once these shows are over ...
Anyway, this is the ingredient list .. they were 'no bake' which makes more sense to me given baking anything with protein powder in it probably isn't the best idea (?)
400g protein powder
200g rolled / quick oats
250ml skim milk or unsweetened almond milk
100g natural peanut butter
mix all of the above together, spread evenly into a large flat dish or tray and stick in the freezer until it sets ....
My attempt turned out a little sticky because I ended up adding an extra cup of skim milk to get the mixture going ... in hindsight I probably should have split the ingredients into two or three smaller mixing bowls as that would've made it easier to get moist with just the one cup of milk.
So if made exactly as laid out above you can get 16 bars and the macros per bar work out at 25p / 14.5c / 5f (given you're using a protein powder that's around 85g / 100g)
I'm going play around with the ingredient amounts to alter the carb & fat content ... there's a terrific new product that's just come out in Australia, a powdered peanut butter called PB2 that packs 40g protein / 40g carbs & 12g fat per 100g .... you just add water to make it into a paste... adding cinnamon, raisins, dried banana, crushed oreos ect ect ect are all delicious options too !
