Preheat oven to 350 degrees.
Prepare baking pan by spraying with cooking spray, then coasting lightly with 1/8 - 1/4 cup flour. Set aside.
In a large bowl, prepare cake mix per package directions. (A gluten free yellow cake mix will work well for this recipe.)
Mash or puree bananas. Add mashed banana and spices to cake batter. Mix well.
Gently fold in chocolate chips.
Bake at 350 degrees for 40-50 minutes. Don't overtake. Bread will be done when a knife or toothpick inserted into the center will come out clean.
Remove from the pan while still warm. Serve warm or cold. If desired, serve with a dollar of whipped cream and/or chocolate syrup.
