These Vanilla Greek Yogurt Chocolate Chip Cookies taste like cake. Scratch that. Better than cake because they’re bite size. They’re super dense without losing any of the flavor of traditional chocolate chips. With the addition of vanilla Greek yogurt, I almost like them more. I tried to lighten up your classic cookie with egg whites, powdered sugar plus coconut sugar and non-fat Greek yogurt instead of butter. They might not be the prettiest cookies, but boy, are they delicious!
