Pumpkin Spice Cupcakes

A couple of months ago my roommate had some leftover pumpkin guts from some pies she made.  One lazy Sunday afternoon I converted them into pumpkin spice cupcakes with ginger cream cheese frosting:

I used this pumpkin cupcake recipe from How to Eat a Cupcake, though I substituted dark brown sugar and granulated sugar for the light brown sugar.  For the frosting I turned to Chockylit's trusted cream cheese recipe, but with ~1/8 cup of diced candied ginger thrown in.  I garnished the cupcakes with graham crackers as an homage to my roommate's pumpkin pies.
