This very much reminds me of the Monster Java Mean Bean flavor, which is a good thing because I like that taste a lot! I have not had gooey butter cake, so I can't really compare that flavor, but it does taste good. I would not drink this daily however, as it is very sweet. Of course I do like the idea of having an occasional morning treat. I think the caffeine content is great and not having to fetch Mean Beans from the store is convenient. Overall I will be saving this for whenever I'm craving coffee or sugar, instead of making it a ritualistic daily thing (unlike the Charged Refreshers).
