Preheat oven to 350 degrees.
Using your fingers or a brush, grease the bread pan with two tablespoons of softened butter.
Line the bread pan with parchment paper and leave enough paper to overhang the bread pan's edge.
Into a bowl, mix with a wire whisk or a fork the dry ingredients: sifted all-purpose flour, sugar, cinnamon, pumpkin spice, baking powder, baking soda, and flaky sea salt.
Into the bowl of a stand mixer, add the wet ingredients: eggs, pure vanilla extract, pumpkin puree, mashed bananas, cream cheese, and coconut oil.
With the bowl mixer set to a low mixing speed, little by little, add the dry ingredient mixture to the wet ingredients until the ingredients are thoroughly incorporated.
Next, fold in the semi-sweet chocolate chips.
