Mixed Berry Banana Bread

Preheat the oven to 350 °F. Line a 9-inch loaf pan with parchment then grease the parchment with cooking spray. In a medium bowl, whisk together the flour, sugar, baking soda and salt. Set the mixture aside. In a separate medium bowl, stir together the mashed bananas, buttermilk, eggs, vegetable oil and vanilla extract. Lightly stir the banana mixture into the dry ingredients with a rubber spatula just the batter looks thick and chunky. Add the berries and fold just until combined then scrape batter into the prepared loaf pan. Sprinkle the top of the batter with a generous amount of sanding sugar (optional) then bake the bread for 55 minutes or until a toothpick inserted comes out clean. Allow the loaf to cool in the pan for 5 minutes then transfer it to a cooling rack to cool completely. Slice and serve.
