★ Tips & FAQs ★
I like the authentic taste of graham crackers however, you can also use cinnamon toast crunch cereal in place of graham crackers if you don't have those on hand. This will make things a bit sweeter and will add a touch of cinnamon — not a bad thing at all!
Well, start with the Rice Krispie treats you know and love and then imagine a s'mores flavor with a hint of oatmeal. That's pretty much exactly what you're getting here. These homemade treats taste almost identical to the Quaker Oats chewy s'mores flavor granola bars.
Yes! Want to mix up the flavor? Try using peanut butter instead of the butter. Just add the peanut butter after you microwave the marshmallows.
