S'mores variations

My cousin's variation on s'mores is to replace the chocolate bar with a Caramello bar. This adds some carmel into the mix. I do like this, but it is quite sweet.
My sister's s'more variation replaces the marshmallow. She puts a banana that is still in it's skin into the coals of the campfire until the skin is black. Peel the banana and use the hot banana in place of the marshmallow. I've never tried this since I don't like cooked bananas.
My variation is to add coconut. It's best if you toast it before you pack it to take camping. I also make a s'more where I add peanut butter.
