After my cookies taste not promise, but I wanted to try another powder in the hope that it tastes better. And I was not disappointed. Although the powder still foamed very strong, but drunk with a straw, you can tell them nothing more. But the banana flavor is indeed artificial, but it's like always shakes that you can buy. I find it tasty and would advocate but if there were sample sizes for 2, then I could have saved my cookies misstep. Otherwise, I think banana delicious.
