Generally the rule is: the darker the chocolate, the more delectable. But even the most pure cacao chocolate bars can be loaded with sugar and calories, which makes it less fun to indulge in. Lily's Sweets changes that with the 70% Extra Dark Chocolate Bar that uses zero-calorie stevia as a sweetener, reducing the overall calories of every bar by 25 percent. Its low glycemic index also means it's safe for diabetics. Lily’s Sweets only used fair trade certified cocoa and natural ingredients that are non-GMO, gluten-free, and absolutely delicious—so finally there's no need to stop at one square.
