In a small bowl mix the sugar and cinnamon together.
¼ cup White granulated sugar, 1 teaspoon Ground cinnamon
Preheat oven to 350°F. Spray a 9X5-inch loaf pan with non-stick baking spray. Line the bottom and 2 sides with parchment paper. Spray again. Sprinkle the cinnamon sugar in the pan. Shake the pan until it is coated. Pour the excess of cinnamon sugar into a bowl to use on top.
In a medium sized bowl, sift together the flour, baking soda, salt, and cinnamon. Set aside. Mash bananas on a plate. Use a fork or a potato masher to mash them. Melt the butter in the microwave, let it cool to room temperature before using.
2 cups All-purpose flour, 1 teaspoon Baking soda, ½ teaspoon Salt, 1 ½ teaspoon Ground cinnamon, 3 Overripe bananas, ½ cup Butter
In a separate large bowl, mix the melted butter, brown sugar, sour cream, mashed bananas, vanilla, and eggs. Use a whisk to mix together.
¾ cup Brown sugar, 2 Large eggs, ¼ cup Sour Cream, 1 teaspoon Pure vanilla extract
Add the dry ingredients into the wet. Whisk until just combined. Pour in the mini chocolate chips and mix until combined.
¾ cup Mini chocolate chips
Pour the batter into the pan. Top with the extra cinnamon sugar and extra mini chocolate chips.
Bake for 50-60 minutes until a toothpick inserted comes out clean.
Let it sit for 10 minutes in the hot pan. Then, transfer the loaf to a cooling rack. Let it cool completely before cutting into it.
