Preheat oven to 350. Lightly grease a 9x13 pan (I used Pam)
Using an electric mixer, combine all ingredients except for the flour. Make sure to blend well. Then add the flour, 1 cup at a time, to the mixture and stir with a spoon. Put mixture into pan and bake for 35 min. or until toothpick comes out clean. Remove from oven and top with chocolate chips. Allow them to melt and then spread evenly. Allow to cool, then cut into squares.
