Can use quick or old fashioned oats. You can skip the toasting step, but I find it adds a great flavor.
Can use either honey or Karo(R), or any combination of the two.
Can use maple syrup in place of the agave, if that is more your taste.
Instead of almonds and chocolate, can use 1 1/2 cups of any mixture of nuts, seeds, dried fruit, or chips. Anything that might melt, should be sprinkled along the bottom of pan, otherwise it just melts and blends in when adding the peanut butter mix. Everything else can be mixed in the with oats.
