I have a recipe-
1 jr natural pb, (16 oz)
2cups vanilla flavored wheyprotien powder,
sweetener if your whey pwd isn't sweentened already, unsweetened shredded ccnut-
Roll into 1 inch balls
(optional dip in melted sugar free choc bars) You probably could do unsweet baking choc +sweetener but it would have to be tempered.
Anyways it says 3 carbs per ball- and it sounds like you are doing the same thing- except w/o protien powder- so your would be less.
