Preheat your oven to 350°F (175°C). Lightly coat a loaf pan with nonstick spray or line it with parchment for easy release.
Prepare the apples: In a small bowl, combine chopped apples, brown sugar, cinnamon, and ginger. Toss gently and set aside.
Mix the wet ingredients: In a large bowl, whisk together egg, granulated sugar, oil, sour cream, and vanilla until smooth and creamy.
Add the dry ingredients: In another bowl, mix flour, baking soda, and salt. Gradually fold this into the wet mixture until just combined — don’t overmix!
Add apples: Fold in most of the apple mixture. Pour the batter into your prepared loaf pan and smooth the top.
Top it off: Spoon the remaining apple mixture over the batter and gently press it down.
Bake: Bake for 50–55 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Let it cool in the pan for 30 minutes, then transfer to a wire rack.
Glaze: Whisk together powdered sugar, vanilla, and milk until smooth. Drizzle over the cooled bread and let it set.
