Honestly i have liked making my own, i get the "better protein bars" from NTBM (i only use a few things from there btw) and add in a bit extra whey and oat meal and they are pretty good. I make 12 each batch and then freeze an extra batch for later on. ends up costing like 1-2$ a bar and it alot better for you then most of the bars at the store.
other then that i only buy one if im out n about and happen to be out of protein. normally i take a shake with me in an empty water bottle..
not a big fan of protein bars, but when i do have em, i usually make em.... just been lazy laity..... I should make another batch.
adding cranberries is also a nice touch.
if you want to do it from scratch im sure there is a bunch of ways how to online, just DONT put extra water... put less if anything and add a drop if you need more. only takes a drop too much to make the bars more like pudding...
