i don't know how you mark st. patty's day... but this is the way i like to do it: cupcakes!
shamrock cupcakes... yep they're really green! they use pistachio pudding mix and chocolate chips (of course!). recipe here.
I've been enjoying these festive treats ever since i was a kid - and other children at school would exclaim "ugh - why is that muffin green!?".
This post goes out to my number 1 cupcake enjoying friend - who i miss dearly.
