Nonstick cooking spray, for the loaf pan
1 overripe banana
⅔ cup sugar
8 Tbsp (1 stick) butter, melted and cooled
½ cup plain Greek yogurt
1 Tbsp orange juice
1 tsp vanilla extract
1 large egg
1 tsp baking soda
½ tsp kosher salt
1 ½ cups plus 2 tbsp all-purpose flour
1 cup diced ripe peaches
1 cup blueberries
1. Preheat the oven to 350ºF. Spray a 9-by-5-inch loaf pan with cooking spray. Line the pan with overhanging parchment and spray the parchment.
2. Mash the banana in a medium bowl with a fork. Add the sugar, butter, yogurt, orange juice, vanilla and egg and whisk.
3. Mix together the baking soda, salt and 1 1/2 cups of the flour in a bowl. Fold the dry mixture into the banana mixture with a spatula. Toss the peaches and blueberries with the remaining 2 tablespoons flour and fold into the batter. Pour the batter into the prepared pan.
4. Bake until a toothpick inserted in the center comes out clean, about 50 minutes. Let cool in the pan for 10 minutes, then use the overhanging parchment to transfer the loaf to a rack to cool completely.
