Pumpkin Bars with Cream Cheese Frosting

I decided to make something different this year for Thanksgiving.  I absolutely loved these bars!  They are definitely a keeper.

1 cup flour
1 cup packed brown sugar
3/4 cup canned pumpkin (about 1/2 of a 15oz can)
1/2 cup butter, softened
2 eggs
1 tsp vanilla extract
1/2 tsp baking soda
1/2 tsp salt
1/2 tsp cinnamon
1/2 tsp nutmeg
1/2 tsp ground cloves
**1/2 tsp pumpkin pie spice
**1 cup mini chocolate chips

Combine flour, brown sugar, pumpkin, butter, eggs, vanilla, baking soda, salt, cinnamon, nutmeg, and cloves in a bowl; mix well. Spoon into a 13x9-in baking pan. Bake for 20 min. Let stand and cool.

Frosting:
1 lb pkg confectioners sugar (I NEVER use this much)
1/4 cup butter, softened
3 oz cream cheese
1/2 tsp vanilla extract
milk

Combine sugar, butter, cream cheese, and vanilla in a mixer bowl; beat until blended, scraping bowl occasionally. Beating constantly, add enough milk to the frosting to achieve the desired consistency. Spread frosting over baked bars. Cut into bars.
**Sprinkle mini chocolate chips on frosting for garnish if desired

**optional...it's what I added to it first time around and it was awesomeness!
