Fall baking

It's fall again and I'm baking some cupcakes. Ok, so right now I'm sitting here waiting for things to be room temperature as the Joy has instructed me to do. Ben is recording the songs he's written lately so everyone is tiptoeing and whispering so we don't mess it up :-). I got some pastry flour and am hoping it will yield similar results to cake flour, but that was all the Co-op had.
Anyway, I'm using the 4-Egg Yellow Cake from the 75th Anniversary Edition of The Joy of Cooking. I plan on making Quick Chocolate Butter Icing. Wish me luck!
