Shake Shack - Boston Cream Pie Custard

I looooooove me some Boston Cream Pie!  So of course I had to try Shake Shack's custard version which was available in April, woo!

I have to admit, when I first took a bite, I thought maybe they had given me their regular chocolate custard at first, haha.  But I did check, and was told that the Boston Cream Pie custard consists of their vanilla custard with fudge mixed in - so, essentially like a concentrated chocolate custard, haha.  It didn't necessarily taste like a Boston Cream Pie, but it was yummy regardless :o)
