Preheat oven to 375 degrees F. Grease and flour a 9" x 5" loaf pan. Set aside.
In a large mixing bowl, whisk together the dry ingredients: flour, baking soda, baking powder, salt, cinnamon and cloves.
In a large measuring cup, mash bananas. You should have 1 cup of the mashed mixture from 2 medium bananas. Add eggs, oil, sour cream, vanilla and sugar. Whisk together.
Add wet ingredients to dry ingredients and stir with a spatula. Do not overmix.
Pour batter into prepared pan.
Bake bread for 10 minutes in 375 degrees F. When the timer beeps, do not open the oven door but lower the temperature to 350 degrees F. Bake bread for 30 more minutes OR until the top is cracked and golden brown and the toothpick inserted in few spots in the center of the bread comes out almost clean.
Cool bread in pan completely.
Brush bread with melted butter. Sprinkle with cinnamon sugar. Slice and enjoy!
