Preheat oven to 325 degrees (F). Generously grease a bundt pan with non-stick cooking spray; set aside.

In the bowl of stand mixer fitted with the paddle attachment beat butter and sugars until light and fluffy - about 5 minutes. Add eggs, one at a time, beating well after each addition.

Add mashed bananas and vanilla extract.

In a seperate bowl, mix together flour, salt, and baking soda.

Add flour mixture alternatley with the buttermilk, beginning and ending with the flour.

Pour finished batter into the prepared bundt pan and bake for 55-65 minutes, or until a cake tester inserted in the cake comes out clean.

Cool cake in the pan for 10 minutes, then run a knife gently around the edges, and carefully turn out onto a cooling rack. Cool cake completely before cutting/ adding drizzle.

For the drizzle - Combine chocolate chips and milk in a microwaveable bowl. Heat in 20 second increments until chocolate has been completely melted and can be whisked into a smooth mixture. Let the chocolate mixture cool for a few minutes, then pour into a large ziplock bag and snip a small corner off one end. Generously drizzle chocolate over the cooled cake. Cut and serve!

Oh, and feel free to garnish with sliced bananas if you want an extra pretty presentation :)
