My sister in law, Lydia, gave me this recipe years ago; guess she was tired of my Banana Bread and Banana Choc Chip Muffins? It soon became a family favourite.

1 cup Butter, softened
2 cup Sugar
2 Eggs
1 teaspoon Vanilla
4 mashed Bananas <–not four cups of mashed bananas like I did once!!! O.O

3 cups Flour
2 teaspoons Baking Soda
2 teaspoons Baking Powder
pinch of Salt

1 cup Sour Cream

Topping 
1/2 cup Brown Sugar
2 teaspoon Cinnamon
1 1/2 cup Chocolate Chips
Preheat oven to 350F
Lightly spray a 9X13 with Vegetable Oil Spray

Topping
In small mixing bowl, combine Brown Sugar, Cinnamon and Chocolate Chips; set aside.

In another small mixing bowl, combine Flour, Baking Soda, Baking Powder and salt; set aside.

Cream Butter with Sugar and add 1 Egg at a time.
Beat until light and fluffy.
Stir in Vanilla and Mashed Bananas.

Add Flour, BS, BP and salt to creamed mixture alternately with the Sour Cream, ending with the Flour mixture.

Spoon and spread 1/2 the batter into greased 9X13 pan. Sprinkle with half the Brown Sugar/Cinnamon/Choc Chip mixture.

Spoon remaining batter into pan, spread evenly and top with remaining Brown Sugar/Cinnamon/Choc Chip mixture.

Bake in 350F  oven for 50 – 60 minutes, or until toothpick inserted comes out clean.
Cool, in pan, on wire rack until completely cool.

Cut into Squares and transfer to airtight container.
