2 sticks margarine
1 lb light brown sugar
2 cups flour
1 tablespoon baking powder
1 bag chocolate chips
1/2 bag butterscotch chips
Melt butter in a large bowl. Stir in brown sugar. When cooled, add eggs, flour, and baking powder. Stir in chocolate and butterscotch chips.
Bake at 350 degrees in a greased 9X11 glass pan for 30 minutes. The center is usually gooey. I love the edges so I cook mine a little longer to get the center a little more stiff. Don't over cook or it will burn! I love it best when it is completely cooled.
My favorite portion of this pan of goodness?? The sides!!! I was so happy when I found this pan. I can make square brownies that are all like the sides!!!
