Blueberry Boy Bait

How could I resist a recipe with this name?  It could be almost anything and I'd try it with a name like "boy bait"--but in this case, the combination of cake and blueberries was also a really good one.  The recipe is from Smitten Kitchen, and I followed her lead in using buttermilk instead of whole milk.  I used frozen wild blueberries, because that's what I had; they're much smaller than the berries currently available.  I bet this would also be good with raspberries (though the name wouldn't flow quite as well.)

I don't know if the cake is supposed to attract blueberry boys or boys who like blueberries.  So far, this is the only boy who's tried (to try) it.
