Place butter and sugar in the bowl of a standing mixer and cream together for 3 minutes or until light and fluffy.
Add eggs one at a time, then bananas, milk and vanilla until combined.
In a separate bowl whisk together the flour, baking soda and salt.
Gradually add the dry ingredients to the banana mixture followed by the chocolate chip cookies and mix until just combined making sure not to overly crush the cookies.
Pour the batter into a greased 8.5 x 4.5 loaf pan and bake for 1 hour or until a toothpick inserted into the center comes out clean.
Allow the bread to cool for 10 minutes and then remove to a cooling rack.
* To freeze: Wrap the bread and then place in a labeled zipper bag for up to 3 months.
