Wow, what a coincidence, I thought of doing this yesterday. Most recipes I found had a mix of peanut butter, oatmeal and whey protein (with a little water or milk for moisture) with a 1:1:1 ratio, so I tried making a tiny batch of only two to try it out and it worked perfectly! I love anything with pb in it and this recipe tastes awesome and is super cheap. However, I carried one of the bars around with me for a few hours and it got quite doughy, but I didn't mind that. If you get them straight from the freezer/fridge they've got a great chewy consistency, though.
I'm going to try making a proper batch sometime soon. I might post some pics of my creation later on. But yeah, I had no idea it would be so easy, tasty and cheap!
Edit: Okay, here goes. This is the result of my Saturday morning. The recipe was somewhat improvised, but I think it turned out quite well! Hope some of you find this helpful. I'm not sure this post necessarily belongs in this thread, but whatever.
Here's what you'll need:
12 oz/350g oats
12 oz/ 350g whey protein
12oz/350g peanut butter
I also put about 100g of shelled hemp in there to get some essential fatty acids and a bit more protein, but that's optional.
Put it all in a bowl, like so:
Now mix that shit up good! (probably a bit more than I did for this pic) Add some more water or milk if it's still too dry; it should be quite sticky.

Lube a pan up! I think mine's a 8 x 12, but I'm no good with pan measurements.

When the pan's all lubed and ready to go, put all of your sticky mix in there.

Now it's time to smooth things out, so pat down the mix until it's nice and firm.

Now you put that sumbitch in the freezer and let it chill for an hour or two. Afterwards it's time to cut the sucker up into pieces I get about 16, but you can obviously make them as big as you want.

Bam!
Here's a finished one. I couldn't be bothered to keep it in the freezer long enough, so it's a bit soggy:

Now, according to my hasty calculations, one piece (out of the 16) amounts to roughly:
327kcal
27.4 protein
18.1g carb
16.8g fat
3.8g fiber
Not too bad! You can obviously experiment with this recipe yourself as it is pretty straightforward.
