You can omit the PB layer to make them just s'mores this filled 9 muffin size liners, but I'd say 1/2 is a serving size since they are large I recommend using my homemade marshmallow fluff since it's MUCH cleaner ingredients than the traditional fluff you'll see on the shelves. You can even make It sugar free with granular monkfruit in place of organic cane sugar or honey
