Homemade food items should have some kind of benefits over store bought ones, like restoring more food or stamina. The novelty of baking the food yourself kind of wears off after you realize you just spent 65 points in ingredients on 15 points worth of cookies you could have just bought directly.
Speaking of, chocolate shouldn't be immediately consumed by one dough ball to make cookie dough, being able to use it on at least two would make up for it's buying price in the resulting cookies. If it can check, maybe have it depend on the amount of bites left the chocolate has, consuming some when used in the cookie dough recipe.
