Add peanut butter, coconut sugar, vanilla, maple syrup to the food processor, process for a minute to mix the sugar.
Add chocolate, salt, 1 cup krispies and pulse to mix and break most of them. Add the remaining rice krispies and pulse to mix and break half of the krispies.
Shape using hands or a scoop. Hands will warm the nut butter making it easier to bind. If using a scoop you might need to add maple or oil so that the mixture sticks easily as some nut butters are dryer.
Shape, chill for a few mins and serve. Store refrigerated for upto 2 weeks, freeze for upto a month.
