Toll house Marble Squares

My Mother made Toll House Marble Squares for her eight children when I was a little girl. They were a new taste sensation! I baked them for my little girls and the taste and smell reminded me of my childhood. When my girls were away at school I put them in care packages. I just sent my niece an antique toll house tin full of the squares and received great kudos from her. today I baked another batch of these bars for my grandchildren...and the beat goes on.
