While both cake and flourless chocolate cake are both sweets and should be consumed in moderation, a flourless chocolate cake is, on the whole, healthier than a regular cake. For starters flourless cake is naturally gluten-free making it less dense and carb heavy compared to a traditional chocolate cake. The second reason this flourless chocolate cake is healthier than a regular cake is the lack of added sugar. Instead of whipping cups of butter and sugar together, the sweetness comes from the bittersweet chocolate.
