Pumpkin Bars

I've made three batches of these in the past week and have taken them all over town. Super easy and really good. Not heavy, really flavorful - from Penzey's Spices

Pumpkin Bars with Cream Cheese Icing
1/2 cup butter, soft (1 stick)
1 cup brown sugar
2 eggs
2/3 cup canned pumpkin
1 teaspoon vanilla extract
1 cup flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1 teaspoon cinnamon
1/4 teaspoon powdered ginger
1/4 teaspoon ground nutmeg

Preheat oven to 350. Cream the butter. Add the brown sugar, eggs, pumpkin and vanilla and mix well. In a separate bowl, sift all of the dry ingredients together. Gradually add to the wet mixture and mix well. Pour into a greased 9x13 inch pan and bake at 350 for 15-20 minutes (mine took about 25, toothpick will come out clean). Let cool and top with brown butter icing.

(The recipe ices the bars with a brown butter icing, but I was sick of cooking and had cream cheese in the fridge so I went with a cream cheese icing instead. Awesome):

1/2 block of cream cheese (4 oz?, can use more)
2 cups powdered sugar

Mix well and spread over cooled bars. Cut into squares.
