Oatmeal Chip Bars

Here is a spin on chocolate chip cookie bars which I am sure will be a crowd pleaser.  I may have to try these...wonder if my co-workers will have a problem being the guinea pigs in this project!  LOL

1 C. butter or margarine at room temperature
1 1/4 C. brown sugar
3/4 C. white sugar
2 eggs
1 tsp. vanilla
2 C. flour
2 tsp. baking powder
1/2 tsp. salt
2 C. quick cooking or regular oats
3/4 C. chocolate chips
1/2-3/4 C. butterscotch chips

Preheat the oven to 375 degrees.  In a mixing bowl, cream together the butter or margarine, sugars, eggs and vanilla.  In a separate bowl, combine the flour, baking powder and salt; gradually add to the creamed mixture.  Fold in the oats, chocolate and butterscotch chips.  Spread in a greased 10x15 rimmed metal pan, using a spatula or your hands to press into place.  Bake for 20 minutes at 375.  Cool, but cut the bars while still warm, as a knife will go through them more easily.
