Pumpkin Spice Rice Krispies Treats

These pumpkin spice rice krispies treats are filled with warm spices and a lovely airy crunch. I use more cereal than typical rice krispies treats recipes, so the treats are less gooey, more light and crunchy, and not too sweet. Toasted black sesame seeds add a hint of nutty and bitter flavor that balances nicely with the sweetness of marshmallows.
