1.  Coat a 9" x 13" baking dish with nonstick cooking spray, then flour.  In a large bowl, combine the 2 cups flour, the baking powder, baking soda, salt, sugar, 1/2 cup brown sugar, 1 teaspoon cinnamon, the butter, milk, and eggs.  Beat until well combined: pour into the baking dish, then cover and chill for at least 8 hours or overnight.

2.  Preheat the oven to 350 degrees.

3.  In a small bowl, combine the remaining 1/2 cup brown sugar and 1 tsp. cinnamon with the pecans.  Sprinkle over the chilled batter and bake for 30 to 35 minutes, or until a wooden toothpick inserted in the center comes out clean.  Cut and serve warm.  12 - 15 Servings
