This was my Grandma Bure's recipe and she made it for me when I was a little girl. Yep, I loved chocolate even then. I remember making this in the kitchen with my mom and with my own children as they were growing up. It still remains a family favorite. Recently I made 4 batches that were consumed by my daughter's college soccer team. They didn't last long. Enjoy!
Stir together flour, baking powder and salt and set aside. In another bowl, melt butter and add brown sugar. Mix well. Cool slightly and add 1 egg at a time, beating well after each addition. Add dry ingredients to this. Finally, add chocolate chips, nuts and vanilla. Pour into a greased 9 x 13 pan. Bake at 350 for 35 minutes. When almost cool, cut into finger-length bars.
