I made these cupcakes after sampling a port at my brother's house a few weeks ago. He loves port. He likes sweet wine. I like it after dinner sometimes. Mostly, I drink it when I go to his and my SIL's house. I used it last year for a really great roast pork tenderloin with fig and port sauce. Not a BIWB thang, so you're on your own for that one.
I used several recipes, and probably didn't follow any one in particular. I made these buttermilk chocolate with port cupcakes based on the Sweet Chocolate Port Cupcakes from Cupcake Wars. I did not include the filling. I made the port reduction from this same recipe. The frosting is my old stand-by buttercream, and I used port wine and port reduction in the frosting to substitute for the liquid. The port reduction added a nice and subtle fruity note to this frosting. B-E-A-U-TI-FUL color. My favorite sugar pearls added just that little bit of elegance and savoir faire.
