Chocolate Iced Cookie Bars

Seems like I often find myself in a position where I need a treat--quick. Not just I have a craving, (that does happen too), but I need to deliver a treat to someone, quick. Now I can make a batch of Food Processor Cookies and have them ready to go in 30 minutes but a girl needs choices.
I saw this recipe on Lizzy's blog and knew I had to make them. I'm happy to say they were plated and out the door in under 2 hours! Bar cookies are perfect for a quick treat especially if you help them 'cool' in the freezer. It does work.
This bar cookie was rich with butter and dark brown sugar. The frosting was an added bonus. Don't be afraid to spread it thick, you'll thank me later.

Chocolate Iced Cookie Bars
2 cups plus 2 tablespoons flour
1/2 teaspoon baking soda
1/2 teaspoon salt
12 tablespoons butter, melted and cooled
1 cup DARK brown sugar (7 ounces)
1/2 cup sugar
1 egg
1 egg yolk
2 teaspoons vanilla
Frosting
1/2 cup butter
1/3 cup milk
6 tablespoons cocoa
1 pound powdered sugar
1 teaspoon vanilla

Line a 9x13 pan with foil, spray. Whisk flour, soda and salt in a bowl. In a large bowl combine sugars and melted butter, whisk. Add egg and egg yolk and vanilla stir till smooth. Gently fold in dry ingredients. Do not over mix. Smooth batter in pan. Bake at 325 degrees for 27-30 minutes until golden brown. Cool, lift bars from pan and cool completely. If you are in a hurry (I always am) put it in the freezer for a few minutes.

While bars are cooling make frosting. Combine butter, milk and cocoa in a saucepan. Whisk and cook for about 5 minutes, mixture will just come to a boil. Pour in bowl of mixer. Beat 1 minute. Gradually add powdered sugar, beat until smooth. Add vanilla. Frost cooled bars. Using an offset spreader will make your life easier. Cut the bars and get them out of the house quick. They are dangerously delicious.
