Directions

1. 1
   Pre-heat the oven to 350°F.
2. 2
   Sift the flour, baking powder and salt in a large bowl. Set aside.
3. 3
   Combine the butter and sugar using a mixer until blended.
4. 4
   Add the eggs, one at a time, to the sugar mixture, mixing on low in between each addition.
5. 5
   Add the vanilla and mix.
6. 6
   Add the flour and mix until combined.
7. 7
   Stir in the chips.
8. 8
   Coat a 9-inch x 13-inch pan with nonstick cooking spray and spread the batter evenly into the dish.
9. 9
   Bake for 30 minutes, then cover the top with foil to avoid over-browning.
10. 10
    Bake for another 10-15 minutes, or until a toothpick inserted in the middle comes out with moist crumbs. You will think they are under-done, but they aren't. Make sure you don't overbake!
