Great alternative to preservative filled and/or pricey grocery store granola bars. Perfect on the go breakfast for a busy family.
Recipe is great as is, but when you start to get bored of it, try mixing it up a little. Try cocoa powder, apple pie spice, reese peanut butter bits, peanut butter, trail mix, M&M's, or anything else that sounds interesting to mix up the flavours. I've made this a couple dozen times, and always add a couple extra cups of filler (trail mix expecially). A hint for handling the sticky dough; spray your hands lightly with no stick cooking spray when mixing/patting it into the casserole dish, and it'll handle much better.
These keep very well--I usually get 10-14 days out of the fridge b4 they mould or go 'off', and around a month in the fridge, and have frozen as long as six months.
