Pumpkin Bars with Cream Cheese Frosting Shaaar It fast

My good friend Scott brought me a pumpkin cake last week – a thick 9″ x 13″ cake with a giant pile of cream cheese. After snagging bits of it for days, I finally asked him for the recipe, and he kindly emailed it. After reading it, I realized I had the recipe—it was a match for the pumpkin pie plates I’ve made at nearly every bakery and coffee shop I’ve worked in. It’s been years since I made it, but I was inspired by the delicious cake I made for work and made it into a bar for my kids (who were also big fans of cake).
I spent the afternoon fiddling with the recipe just a bit – trading some granulated sugar with maple syrup and brown sugar, adding spices, and adding a bit of cream cheese and a bit of powdered sugar to the frosting.  We all appreciated the changes, my mom even asked me to bring bars (instead of pumpkin pie!) to Thanksgiving. I’m thinking about it.
