I low-carbed the recipe by using the following ingredient (measurements stayed the same):
unsweetend coconut flakes
RealLemon lime juice
These ended up being pretty high in carbs--no doubt from the lime juice and Splenda. You could make them with water + extract for fewer carbs, but you'd need to play around with the recipe for taste. Also, you can lower the net carbs by cutting the amount of sugar.
The nutritional value below is for the recipe from the link as made using the substituted ingredients.
