i know that sounds a little weird ut i already did it and the taste is really good, i would suggest you to add penaut butter ( that is actually very healthy in moderate amounts) to make the taste more creamy and dark chocolat, because there are researches that prove that it is fantastic for a post workout meal, and you can even enjoy them with a cup of skimmed milk that is also marvelous to recover your muscles and allow them to grow.
i can ensure you that they wont disappoint you, BOOM! ;)
