Red Velvet Whoopie Pies, from Society Bakery.
I photographed a baby baptism yesterday evening, and the family was kind enough to invite us to the party afterwards at their home.  They had these absolutely divine whoopie pies, which I have to confess, I’d never had before!  I actually split one with another guest, since they were enormous and crazy sweet.  I think I see more of these in my future.
