Instructions
Prep
Preheat the oven to 350°F. Grease a 9x5-inch loaf pan with non-stick spray and line the bottom and two long sides with a strip of parchment paper, leaving a 1-inch overhang on each side for easy removal.
Peel and dice the apples into 1/4-inch cubes. In a small bowl, toss the cubes with 1 tablespoon flour and 1/2 teaspoon cinnamon until every piece is matte and dry. Set aside.
Mash the bananas with a fork, leaving a few small pea-sized lumps for texture.
Make the Batter
In a medium bowl, whisk together 1 3/4 cups flour, baking soda, baking powder, 1 teaspoon cinnamon, nutmeg, and salt.
In a large bowl, stir the melted butter with the brown sugar and white sugar until the mixture resembles wet sand. Beat in the eggs one at a time, then stir in the vanilla extract and sour cream until smooth. Fold in the mashed bananas.
Pour the dry ingredients over the wet ingredients. Fold gently with a silicone spatula using broad strokes. Stop when a few visible streaks of flour remain — do not overmix.
Scatter the flour-coated apple cubes over the batter and fold in with 5 to 6 gentle strokes until evenly distributed.
Bake and Cool
Transfer the batter to the prepared loaf pan and smooth the top into a gentle dome. Bake for 55 to 65 minutes.
Check at the 40-minute mark. If the top is deep golden brown, tent the pan loosely with aluminum foil and continue baking. The bread is done when a toothpick inserted into the center comes out with moist crumbs but no wet batter.
Cool in the pan for 15 minutes, then use the parchment overhang to lift the loaf onto a wire rack. Cool completely (at least 30 minutes) before slicing.
