Three guesses as to what was the most decadently delicious thing I tasted this week.

That's right: Whoopie Pie Frozen Custard.

This bit of sweet manna was the special flavor of the day on Thursday, September 30th at Old School Frozen Custard in Capitol Hill. Now, if you don't know much about Old School, then let me learn you a bit about their M.O.: they generally have only three flavors available daily--vanilla, chocolate, and a special flavor of the day. Naturally, Audrey (who is also the one who inspired these cupcakes) and I had to walk over to sample this one.

So what exactly is Whoopie Pie frozen custard? Well, according to Old School's site, it's comprised of "Our Chocolate Cake Batter frozen custard with a delicious butter cream varigate folded into it".

But really, this description doesn't tell you much about the exquisite joy of eating it. While eating it, the first flavor that hits is chocolate--but then something happens. A slightly tangy, rich-sweet undertone to the taste--that's the cake batter. And then--little nubbins of vanilla buttercream swirled throughout--something that isn't really necessary, but sure is nice.

While had I been given this custard blindly and asked what flavor it was, I might not instantly guess "whoopie pie", but I certainly would have finished it and licked the bowl. Yes, indeed.

The final word? A fine flavor of the day. Bring it back soon!
