Shake Shack - Banana Bread Custard

I was pretty excited to try out the Banana Bread custard at Shake Shack, mainly because banana bread has become a good go-to recipe when I have ripened bananas at home.  

As you can see, this custard looks like plain vanilla, but had a lot of flavor once I ate a spoonful.  My main concern with a banana flavor was that it would taste artificial - does anyone actually like those weird candy bananas??  This custard fortunately had none of that weird fake banana taste, and tasted like real bananas with a hit of a caramel-ish flavor as well.  If I had this again I would probably add chocolate chunks, as that's what I normally do when I bake real banana bread :o)
