The most Fluffy Yogurt Cake recipe made like a soufflè, soft like a pillow, flourless and so easy to make!Made with only 5 ingredients this cake is inscredibly moist and melt in your mouth. It's a gluten free cake, perfect for celiac people, it features no fat (no oil, no butter!) and it's low calorie.Since the cake is very light, I suggest to not skip the flavoring: I've used vanilla paste (or vanilla extract) and lemon zest, but you can also use orange zest or skip the zest and increase the vanilla amount.Perfect served at room temperature or chilled in refrigerator during the hot season, everybody will love it!
