Begin by preheating your oven to 350 degrees.
Grease a bundt cake pan (or two loaf pans) and set aside.
In a large mixing bowl combine the flour, salt, baking soda, baking powder, sugar, and brown sugar. Stir well.
Add the eggs, oil, vanilla extract, pudding mix, milk, and mashed bananas.
Mix well with a hand mixer for about 2-3 minutes or until the batter is smooth.
Stir in the butterscotch chips with a large spoon or spatula.
Pour mix into the greased bundt cake pan and bake at 350 degrees for 55 to 60 minutes or until a toothpick comes out clean from the middle.
