There are 12 grams of carb per Peanut Butter Cup with 10 of those grams coming from sugar. That’s too many for a keto diet. However, with this homemade version, you can enjoy the chocolate peanut butter taste while eating real, unprocessed foods at the same time. It’s a win-win. If you like, you can check the listing with the FDA directly and view the nutrient profile for yourself.
