Oatmeal Bars with Dates and Walnuts
adapted from Martha Stewart's Cookies

1 cup finely ground old-fashioned oats
3/4 cup whole wheat flour
1 1/2 cup old fashioned oats
1 1/2 teaspoon baking powder
1 teaspoon salt
1 tablespoon cinnamon
1/2 teaspoon allspice
1 1/2 cups brown sugar
1 1/2 sticks butter, softened
3 eggs
2 1/2 teaspoons vanilla
1 1/2 cups walnuts, chopped and toasted
1 cup dates, chopped

Preheat oven to 350.  Stir together ground oats, flour, 1 cup whole oats, baking powder, salt, cinnamon and allspice in a large bowl.  Set aside.  

Put brown sugar and butter into a large mixing bowl.  Mix on medium high speed for about 3 minutes, until light and fluffy.  Add the eggs - one at a time.  Mix until well combined.  Add the vanilla.  Scrape down the sides of the bowl as needed.  

Reduce speed to low.  Add oat mixture.  Mix until just combined.  Mix in walnuts and dates.  

Coat a 9 x 13 dish with cooking spray.  Spread the batter evenly in the dish.  Top with remaining oats.  Bake for about 35 minutes until browned and set.  Cut into squares.
