If you're watching your carb intake, this low-carb peanut butter chocolate cake is the perfect dessert for you. The cake is made with almond flour and coconut flour, which are both low in carbs and high in fiber. The peanut butter provides a good source of protein and healthy fats, while the dark chocolate is rich in antioxidants. To make the cake even lower in carbs, you can use a sugar substitute like stevia or erythritol instead of regular sugar. Serve it with a dollop of whipped cream or a sprinkle of cocoa powder for a dessert that's both low-carb and delicious.
