Made these up for DH as a low carb, high protein sweet fix. Basically you can make them with any kind of nut butter, I suppose, but maybe you will need some more sweetener then. Cashews have a natural sweetness which goes well with the chickpea flour (besan or garbanzo flour); I choose it because I didn't want to add too much sweetener. The sweetener I used was half agave syrup and half corn malt syrup (not high fructose syrup). Next time I'll try half maple syrup. The egg should be medium, not large.
