Preheat the oven to 350°F and prepare a loaf pan with nonstick spray or lining.

In a medium bowl, combine the chopped apples with brown sugar, cinnamon, and ginger. Mix well and set aside so the flavors can blend.

In a large bowl, whisk together the egg, granulated sugar, vegetable oil, sour cream, and vanilla extract until smooth and fully combined.

In another bowl, whisk the flour, baking soda, and salt. Add the dry ingredients into the wet mixture and gently stir until almost combined, being careful not to overmix.

Fold most of the apple mixture into the batter, reserving a portion for the topping. Transfer the batter into the prepared loaf pan and spread evenly.

Add the remaining apple mixture on top, gently pressing it into the surface.

Bake until the bread is golden and cooked through, allowing enough time for the center to fully set.

Remove from the oven and allow the bread to cool in the pan before transferring to a rack.

For the glaze, whisk powdered sugar, vanilla extract, and milk until smooth. Adjust thickness if needed.

Drizzle the glaze generously over the cooled bread before slicing and serving.
