Unfortunately, this recipe doesn’t work as well with natural peanut butter (the stir kind), so don’t try it. I’d much prefer natural peanut butter, but it doesn’t really melt or hold things together for me, although I’ve had reviewers that have said it worked for them. I suppose it really just depends on the brand.
Try substituting the oats for Cheerios or other similar cereals.
Feel free to mix in other things like peanuts, flax seed, or mini chocolate chips. If you do decide to add chocolate chips, sprinkle them on the top after it cools for 5 minutes instead of mixing them in because they will melt.
