These are really good! I made some substitutions because my pantry was limited. I only had creamy peanut butter (worked fine) and I used 1/3 cup honey and 1/3 cup corn syrup in place of the maple syrup. I'll be looking for a way to make these a little less sweet next time. Just reducing the amount might work fine. I also used old-fashioned oats (worked fine) and instead of graham cracker crumbs, I crushed up a cup of Crispix cereal. This was probably the best part of the recipe--next time I'll add even more for more crunch. I also omitted the raisins. I'm just not a fan. We were hungry, so I tossed them in the freezer for 30 minutes, and out came what my husband proclaimed is his new favorite snack. They are just a little too sweet to eat much of. Thanks for sharing!
